NOS MiniWatt Mullard Mustard Vintage Capacitor 0.022uF 160V (x1)

Description

Note: Price is per capacitor. If you’d like to buy multiples, contact me and we can work out a lower price per cap.  I can take PayPal and most major credit cards. I have shipping set to a flat rate of $3.49, based off what I know it cost to ship them. This is the bare minimum for shipping, anyone outside the USA see below.

If you are an international customer, there will be an additional fee to make up the cost of shipping. Soon I’ll fix this to reflect the cost of shipping to your specific country automatically, without the need for this 2nd step. From my experience, shipping to Tokyo is about $13 and Poland is roughly $10. The further away from North Carolina, the higher the cost

These MiniWatt/Mullard Mustard capacitors tested extremely well across ESR, Quality Factor and Capacitance accuracy, well within 10%, most within 5%. The Insulation Resistance (IR) wasn’t possible to take (precisely) due to the meter reading OL when in the correct ranges of DC test voltages (100V or 250V), but all samples tested at least 1 Giga Ohm @ 250V/60 seconds.

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 600 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. Despite the fact I knew the meter was going to read OL (Overload), it was still a consistency check for the capacitors to ensure high quality. IR is effectively a short stress test.

Testing Date: 12/15/18

Physical Dimensions: .9″ (L) x 0.285″ (W) x 0.285″ (H)

 

Valid Reasons for Returning:

Capacitance is off by more than 10-20% (or whatever the cap spec is)
ESR is at least 20% higher that I reported, remembering to use the same test frequency and a calibrated meter.
Capacitor was damaged during shipping.
Capacitor won’t fit into your location.
You bought a voltage or capacitance value that you can’t use, assuming you didn’t install it, you can return it.
You experience any audible distortion with your new capacitor, I’ll let you swap it or return it. As long as the cap isn’t damaged (electrically) when I get it back.

There are many other scenarios that I might consider, just contact me if you have a question.

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.

Shipping and Related:

Current Shipping Speed: 1 to 3 days

Cost for US Customers: $3.49 S/H

International Shipping Rate: $11.49 S/H

For international, I took the average of the costs to ship to 5 countries throughout the world (Tokoyo, Japan, Poland and the UK). This is the easiest thing to do, even though it will cost me money half the time.
