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: 111mm x 180mm. The PCB can mount: 48 pieces diameter 18mm(pin pitch 7.5mm) electrolytic capacitors, position C1 ~ C48. 12 pieces metal film capacitors (pin pitch 5.0mm), position C49 ~ C60, and C49 ~ C52 can support 5.0/7.5mm pin pitch. CN1 ~ CN4, can mount pitch 7.62mm 2P/3P terminal blocks. 48 pieces diameter 18mm capacitor, if you use YXA 4700uF 35V can get total capacitance 225,600uF/35V, if you use YXF 1000uF 63V can get total capacitance 48,000uF/63V. 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.
