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

Next up we have a very nice General Instruments “Imp” capacitor. This one tested pretty strong, with good ESR readings. Q-Factors aren’t at the top of this list, but still well within the usable range. I just wouldn’t recommend running this guy beyond 300V (half the rated value), while it will run at 600V just fine, de-rating it will increase life. It was very stable during testing, with minimal drift on my Exetech 380193 LCR meter. Leakage current (500/71.4*10^6) is 7 uA, a bit higher than the others (~2uA), which is reflected in the price. Capacitance accuracy is still within the 20% spec, almost at 10%. overall I/V curve looks good, though you can see the slight tilt (reason for the lower Q’s compared to others in this lot). Still, this is a really strong film cap that is well known for it’s tone. 

Dimensions: Length: 2.3″ Width: 0.8″ Height: 0.8″

Lead Length: 2″ (full size)

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.
