Get PriceGeneral Design Rules 4 Reactors: Reactors are used in steps as detuned filters and are connected in series with capacitors. It must be designed to withstand fundamental and harmonic currents. Capacitors: Capacitors forms the core component in APFC equipment and plays a vital role in power factor correction.
Get PriceDepending on the dielectric, ceramic capacitors derate based on the DC voltage applied. The higher the voltage rating compared to the applied DC voltage, the less they derate. So you will have more effective capacitance with the 20V rated part than the 6.3V rated part. This does not apply to (polymer) tantalums, film caps, or electrolytics.
