NOS Sprague 433P 0.47uF 200V Orange Drop capacitors for sale.


1 in stock (can be backordered)


These Sprague 433P epoxy coated METFilm ‘E’ capacitors tested impressively well across all measurements! Sub 5% tolerance accuracy for all capacitors in this group. The Q-Ratings are as expected based on the other 433P cap lots I have posted and ESR measurements look excellent. These 433P caps are some of the most consistent capacitor types tested, in the first collection of capacitor lots.

(Tested on 7/30/18) These capacitors have extremely low drift, roughly 2% or less drift during testing.

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. Minimal drift after initial charging, capacitor approaches steady state and thus low leakage ( I = V/R -> 250V / (115 x 10^6) = 2.174 uA). Where one microamp (uA) is a millionth of one 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 capacitors are from an Engineering 433P Lab Kit collection (acquired from a former Sprague Executive’s estate sale). I have many more of these if anyone is looking to do a bulk purchase, roughly 1000 in total (180 of each value), each kit has 30 capacitors in it (made up of 6 values, 5 caps in each). These caps are as clean as it gets and you can’t ask for much better performance numbers. Don’t miss out!

nt 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.
