These mylar capacitors from TRW tested excellent in capacitance accuracy, both are under 2% tolerance accuracy at both test frequencies. Drift during capacitance measurement readings is nearly non-existent. The ESR and Q-Factor are extremely good, with consistency across both capacitors and minimal drift. Due to how close these two capacitors measurements are, I am selling them as a matched pair.

New 8/9/18: Insulation Resistance taken for each capacitor are all within the expected IR value from manufacturer tables, such as from Kemet and Sprague’s IR vs. Capacitance tables. Very low drift after initial charging, as capacitor approaches steady state and thus approaches its lowest leakage ( I = V/R -> 250V / (110 x 10^6)  = 2.273 x 10^-6  amp). Uni-T UT511 Pro Insulation Tester was used to acquire these values. Insulation Resistance is a measurement of the dielectric impedance to DC voltage. This is why some older insulation testers are called Dielectric Testers. The only other equipment capable of measuring such high resistances are capacitor analyzers like the vintage TO-6A from Sprague.

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.

Guarantee/Return Information:

For customers inside the USA, I do 60 days for NOS items and 30 days for re-certified used itemsReturn 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.
