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: 75mm x 143mm. The PCB can mount: 6 pieces diameter 22 ~ 36mm snap-in terminal electrolytic capacitor(2 pin or 4 pin terminal). 2 pieces metal film capacitors (pin pitch 5.0 ~ 23mm). CN1 ~ CN2, can mount pitch 7.62mm 3P terminal blocks. 6 pieces electrolytic capacitors, if you use USC 10,000uF 63V can get total capacitance 10,000uF/63V, if you use other 15,000uF can get total capacitance 90,000uF. About metal capacitors, normal we use 2pcs MKP-10 0.1uF. If you want buy terminal blocks or capacitors, you can visit our store.
