DC power supply capacitors filter PCB, for upgrade your audio preamplifier or amplifier. Quantity: 1 piece bare PCB (not include other components). The design can be configured as normal capacitive filtering, or CRC, or CLC filtering, depending on the components at V+ V+' / V- V-' positions. FR-4 fiber glass PCB, dual copper layer, thickness: 1.6mm. PCB dimension: 90mm x 175mm. The PCB can mount: 24 pieces diameter 22mm(pin pitch 5 / 7.5 / 10mm) electrolytic capacitors, position C1 ~ C24. 12 pieces metal film capacitors (pin pitch 5.0mm), position C25 ~ C36, and C25 ~ C28 can support 5.0/7.5mm pin pitch. CN1 ~ CN4, can mount pitch 7.62mm 2P/3P terminal blocks. 24 pieces diameter 22mm capacitor, if you use USC 4700uF 50V can get total capacitance 112,800uF/50V. About metal capacitors, normal we use 4x 10nF/100V, 4x 100nF/100V, 4x 1000nF/100V. If you want buy terminal blocks or capacitors, you can visit our store.
