NOS Philips/Mullard MiniWatt Mustard Capacitors 2700pF 400V | Tested w/ Warranty

Description

Welcome
to the first group of my many vintage and precision electrical components sales by
HallmanLabs.com
(HL) to come! I offer both
NOS (New Old Stock)
and
Retested/Re-certified Used parts
, both of which go through rigorous testing before making it into these ads. Many components from the used lots don't make it through and even some NOS items. For example, only about half of my Mallory Plascaps passed all of the testing, in contrast, all of my vintage NOS Sprague 433P engineering kit caps passed! This showcases the importance of testing capacitors, you can never be sure what will test as NOS or better and which NOS capacitors will fail during testing.
Price is for one capacitor! Use make an offer on 2+ items for lower cost.
The capacitors in the photos are the actual items you are bidding on.
Include in a purchase message which row # capacitors you want to order. I will update the list as stock is depleted to reflect what is in stock. If you do not specify within 12 hours of purchase, I will pick out one for you.

Capacitor Information and Performance Numbers:
The performance measurements table was moved to picture form due to a conflict with the mobile version of the EBay app, if you'd like a hard copy of the measurements table just contact me!
These
MiniWatt/Mullard Mustard
capacitors tested extremely well across ESR, Quality Factor and Capacitance accuracy, well within 10%, some within 5%. The Insulation Resistance (IR) tested very good on these
2700pF 400V MiniWatt Mustard capacitors @ 250V and 60 seconds : 700-750 Mega Ohm
.
ESR follows a near ideal trend, in ESR vs. frequency, with very stable results across the entire lot of capacitors. Quality Factor ratings are far beyond the 1/.006 = 166.67 quoted in the Mullard datasheet, shown above in photo 5, with most nearing a
QF of 300 at 1kHz (double the quoted Mullard value) and 650-700 at 120Hz.
Overall this lot performed very well, meeting and exceeding NOS values.
IR is a measure of the dielectric's impedance to an applied DC voltage across the capacitor. I used the Uni-T UT511 Professional Insulation Resistance Tester to check each capacitor in this group and others. Typical readings for IR range from 100 Mega Ohm to 10,000 Mega Ohm and higher, but the reading is highly dependent on the test voltage applied. The lower the capacitance value, the higher the IR should read. IR is effectively a short stress test.
Testing Date: 12/15/18
Physical Dimensions:
.91" (L) x 0.3" (W) x 0.3" (H)
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
All capacitor acquisitions and testing took place in
North Carolina, USA
and all of my capacitors are
shipped from North Carolina
. Hallman Labs is solely owned and operated. In other words, you are helping a small business that just started up when you purchase from HL!
Stop buying capacitors from sellers that don't test anything except the basic capacitance
at one test frequency, using a multi-meter!! (Not even all the sellers check capacitance) Here at Hallman Labs
I guarantee the performance and accuracy
of my capacitors and their quoted performance numbers. This means if you get a capacitor from me that I said has a capacitance accuracy down to 1%, but you read a 10% tolerance instead, I'll refund you for the purchase. Return shipping is the responsibility of the buyer, domestic (USA) or international. Capacitors are tested using a variety of instruments old and new, such as: Sprague TO-6, Exetech 380193 LCR, EDS 88A-IIs, BK Prec. 810C, and more!

"At Your Request" Information
:
If you request it, I will provide a detailed live log of measurements in an excel document for any capacitor/s you want.
I have multiple capacitors that are accurate down to a
thousandth of a percent
and
multiple
100% accurate @ 1kHz
capacitors
with no drift!
At your request
,
I
will show video of the testing taking place
so you can see the numbers yourself.
Note:
I will
only
do this for
someone buying 3 or more items or
if the
item is valued over
.
Any other details you want, like extra pictures, please contact me for that.

Guarantee/Return Information:
Warranty Length USA:
60 Days
Warranty Length International:
30 Days
First, an important note on referencing my performance measurements:
The frequency at which you take your performance measurements will alter the readings greatly. To compare against my numbers, you must use the same frequencies I did (120Hz and 1kHz). Even then, the accuracy of my meter or yours, will easily create a 5-10% difference between us, unless both our meters are well calibrated (mine is). Many meters use 10kHz and 100kHz (or higher) and those values will be nowhere near mine.
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Valid Reasons for Returning:
•
Capacitance is off
by more than 10-20% (or whatever the cap spec says).
•
ESR is at least 20% higher than I reported
, keeping in mind to use the same test frequencies and zero out your meter/s.
• You experience
distortion that you feel is worse than the cap you previously had in
. In most circumstances, I'll allow a return such as this. However, there may be cases or circumstances where I will not allow it.
• Capacitor has been
damaged during shipping
.
• Capacitor
will not fit into your location,
is allowed, as long as you didn't solder it and/or clip the leads.
• You
mistakenly purchased a capacitance or voltage that you can't use
. Assuming it wasn't installed, this is okay up to 30 days out.
There are many other scenarios that I
might
consider. If you feel that you fall into that category, then just message me.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
For customers inside the
USA
, I do
60 days for NOS
items
and
30 days for re-certified
items! Return shipping will be paid by customer.
For
International
buyers I do
30 days on both NOS and re-certified
items.
Return shipping must be paid by the customer.
Invalid Reasons for Returning:
• You installed it into a circuit and partially blew it out, so now the DC Resistance is barely 1 kΩ
•
Anything you did personally, that damaged the part
, likely will not be eligible.
Contact me for special circumstances or clarification on this.

Payment
:
Payment is due in 24 hours
. PayPal is preferred, but contact me if you have an issue with that.
Shipping and Related
:
Please contact me before initiating a return or leaving negative feedback!
Shipping is free for anyone in the USA
, I offer this instead of offering to pay return shipping (since it will benefit more people).
International shipping rates
are offered with an additional .50 handling fee.
Note:
some countries will charge you an additional customs fee, but I can't predict or know that for every country in the world. I suggest contacting your local postal service and ask them if you are unsure of this.
Handling time will be 24-
72
hours
from when the purchase was made (during the week and when possible I'll ship on Saturdays).

Thank you for looking at my products and have a blessed day! If you like our products, please come by the website or go to our Facebook page and leave us a review!
Facebook.com/HallmanLab. Since I have the Master Parts Sheet on my website and that usually can't be displayed here, I held off on displaying it and removed direct email. However, I have seen many EBay ads where they link to a personal site with more details on the same item, this is my intention also! You have to copy and paste it, Ebay has banned all active hyperlinks: HallmanLabs.com. My intention is to give the buyer total access to my performance numbers, especially since EBay's mobile has made it impossible to give real tables in the ad.
Thanks again for shopping at Hallman Labs.
