Film capacitors, also known as plastic film capacitors, refer to capacitors made of plastic films and are divided into polyethylene film capacitors, polypropylene film capacitors, polystyrene film capacitors, polyester film capacitors, etc. depending on the material. . The SCD155K122A3Z25-F is a film capacitor produced by a manufacturer to be used in specific applications.

The SCD155K122A3Z25-F has the capability of working in temperatures of -55°C to +125°C and is qualified to MIL-PRF-123/125HY specifications. It is typically used in applications that need long-term reliability, such as military/aerospace systems, automotive electronics, and medical equipment. It features high dielectric strength, low ESR and ESL, and excellent electrical and environmental stability.

The SCD155K122A3Z25-F is an axial-lead tantalum capacitor with a non-solid electrolyte, consisting of an anode body, a cathode body and metal end caps. The capacitor has a low leakage current, high insulation resistance and no thermal shock damage. The large size of end caps ensures good heat dissipation and low insertion loss.

The working principle of the SCD155K122A3Z25-F is based on the Faraday law of electrolytic capacitors. When the capacitor is connected to an AC power source, the applied voltage will cause a charge imbalance on the plates, resulting in a current flowing through the capacitor, which results in a change in dielectric strength. The capacitance of the capacitor is proportional to the dielectric strength. The greater the dielectric strength, the larger the capacitance.

The SCD155K122A3Z25-F is one of the most reliable film capacitors and is the preferred choice for demanding applications. Its temperature capability, strong dielectric strength and low insertion loss make it an ideal choice for many applications. It can be used in a variety of applications such as power supplies, filters, timing circuits, surge suppressors, and more. The capacitor is also RoHS compliant, making it an environmentally friendly choice.
