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. FR-4 fiber glass PCB, dual copper layer, thickness: 1.6mm. PCB dimension: 70mm x 156mm. The PCB can mount: 8 pieces diameter 30mm(pitch 10mm snap-in pin) electrolytic capacitors, position C1 ~ C8. 2 pieces metal film capacitors (pin pitch 5.0 ~ 23mm), position C9 ~ C10. CN1 ~ CN2, can mount pitch 7.62mm 3P terminal blocks. 8 pieces diameter 30mm capacitors, if you use USC 10,000uF 63V can get total capacitance 80,000uF/63V. About metal capacitors, normal we use 2pcs MKP-10 0.1uF. If you want buy terminal blocks or capacitors, you can visit our store.
