Capacitor Information and Performance Numbers: Tested on 5/18/20

Here is another AJAX/Mallory “Blue Molded”, this is the largest of the Blue Molded that I have ever had in my possession. ESR reading is rock solid stable and is directly competitive with the MiniWatt 0.47uF capacitor I recently listed. Q-Factors are very good, never dropping below 252. Capacitance accuracy is well within the 10% spec, under 2% max deviation. The I/V curve here looks nearly ideal for 0.47uF. Tilt is almost imperceptible.  IR is at 107 MΩ, this gives a leakage current of 250V/107MΩ = 2.336 uA. 

Don’t miss out on that classic Blue Molded tone, in a bigger capacitance value, without sacrificing voltage!

Dimensions: Length: 2.1″ Width: 0.65″ Height: 0.65″
Lead Length: 0.7″

Guarantee/Return Information:
Warranty Length USA: 60 Days
Warranty Length International: 30 Days

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.
