ECW-HA3C302JB

Film capacitors are electronic components that utilize a thin film of dielectric material to temporarily store electrical energy in a capacitor. The ECW-HA3C302JB is a film capacitor specifically designed to meet the high-rating requirements of camera and medical applications, as well as audio and music technology. It is a small, low-cost capacitor with excellent high-frequency characteristics and superior rated voltage stability.

The ECW-HA3C302JB is constructed with a thin film of dielectric material packed between two metal plates. This provides the capacitor with a large capacitance and low self-inductance, along with excellent AC characteristics. Its high-impact construction, temperature stability, and high resistance to vibration also make it an ideal choice for high-rated applications.

The ECW-HA3C302JB is commonly used in medical equipment, as its high-frequency characteristics make it exceptionally suitable for pulse formating and diathermy therapy. It is also popular in camera applications, as it can supply a stable voltage in fast-changing shutter speeds. Its low ESL allows it to supply high-speed currents that are not possible with other film capacitors.

The working principle of the ECW-HA3C302JB, like all capacitors, involves electrons flowing from one plate of the capacitor to the other, creating an electrical charge. The voltage across the plates is related to the dielectric constant of the dielectric material and the area of contact between the two plates, and this determines the capacitance of the capacitor. As the plates are charged, the capacitance increases and the voltage drops, creating a temporary store of charge in the capacitor.

The ECW-HA3C302JB is a reliable, cost-effective film capacitor that is ideal for high-rating applications in medical and camera equipment. Its high-frequency characteristics, temperature stability, and excellent rated voltage stability make it an excellent choice for pulse formating and diathermy therapy, as well as fast-changing shutter speeds. Its low ESL also allows it to supply high-speed currents that are not possible with other film capacitors.
