Film Capacitors

A film capacitor or plastic film capacitor is a type of capacitor that uses a thin plastic film as the dielectric. This type of capacitor, due to its large capacitance per unit volume, is widely used in almost all electronic devices that need to store energy or to filter frequencies. Film capacitors are most commonly used as crossover capacitors and snubber capacitors in AC/DC power supplies and drive circuits where both low losses and small size are critical.

The 335HC5750KR is a film capacitor manufactured by Nichicon. It features a Kapton dielectric and polyphenylene sulfide (PPS) casing, providing excellent temperature cycling stability and maximum capacitance within a given space. It can be used as crossover capacitors for AC/DC power supplies, as well as snubber capacitors on IGBTs, and other applications.

The 335HC5750KR has a maximum rated capacitance of 57.5 μF and a voltage rating of 250VAC. It also has a high-current capability, an operating temperature range of -20°C to +85°C, and a good waveform deviation range (IPC class 3) from -30 to +20. Additionally, the 335HC5750KR offers an extended storage temperature range of -25°C to +85°C.

This device is ideal for use in AC to DC power supplies, especially those requiring significant AC ripple current or Snubbers. It can also be used in applications such as IGBT gate driver, frequency filters, power factor correction and converter/inverter circuits.

The 335HC5750KR works by storing an electrical charge when voltage is applied. This electrical charge is stored in the tantalum pentoxide (Kapton) dielectric layer. When voltage is no longer applied, the charge stored within the dielectric is released.

The 335HC5750KR is designed to provide capacitance, low ESR, low leakage, and high reliability. It is also highly resistant to heat, humidity, and temperature cycling, making it ideal for applications requiring good surge current capability, high-frequency operation, and temperature stability.

In conclusion, the Nichicon 335HC5750KR is a high-reliability film capacitor specifically designed for use in DC/DC converters and power supplies, as well as snubber capacitors on IGBTs. It offers an excellent temperature cycling stability and maximum capacitance within a given space. It has a high-current rating, good waveform deviation range, and an extended storage temperature range, making it an ideal choice for use in AC to DC power supplies and other applications.
