FP : Polypropylene Capacitor: 160Vdc - 1500Vdc
Polyester Capacitor: 63Vdc - 630Vdc
Polypropylene and polyester power capacitors with minimal inductance.
Product description
FP capacitors are designed to operate at very high Peak and RMS currents. To offer the lowest possible inductance they are supplied un-housed with no conventional terminals and are intended to be clamped between two conductive surfaces, possibly heat sinks. This assembly ensures that heat generated within the device is conducted away with high efficiency, allowing maximum RMS currents whilst maintaining a satisfactory temperature rise. As connection is made directly to the capacitor end spray the design has the lowest possible inductance and is therefore of particular use in resonant circuits such as induction heating inverters.
The capacitors can be designed in a wide variety of configurations to optimise size, ripple current rating and temperature rise, if you have a specific requirement or query then please contact us. Detailed ripple current ratings and temperature rise estimates are available on request.
Technical details
