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.

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.
For customers inside the USA, I do 60 days for NOS items and 30 days for re-certified used items! Return shipping will be paid by customer.
For international buyers I do 30 days on both NOS and re-certified used items. Return shipping must be paid by the customer.
This warranty does not include you applying too much voltage for the rating of the capacitor and thus blowing it out. If you return a capacitor that is now reading open or is short circuited, you will not get a refund. The warranty covers normal usage over the period of time listed or if my performance measurements are off for a high end capacitor, like the MiniWatt caps.
