Get PriceHi All, I have an integrated amplifier with 2 6,800uF (1 for each rail) capacitors in it''s power supply section and I would like to add more capacitance to it, now I know that the best practice would be to replace the 6,800uF capacitors with higher value and similar specs but I would like to know anyways: 1. is it "okay" to parallel another …
Get PriceA power supply is a device that supplies power to another device, at a specific voltage level, voltage type and current level. While it sounds simple, power supplies have a lot of little hang-ups that can be very tricky for the uninitiated. This tutorial will try to help explain all about power supplies.
Get PriceThe requirement for "low-ESR" capacitors normally arises in output filters of switching power supplies, where the frequency is relatively high (kHz to MHz). It''s less important in mains filters (including the input filter of a SMPS) where a large capacity electrolytic tends to have a proportionally small ESR so that 100Hz or 120Hz ripple is not ...
