ECW-H12223JVB

Film capacitors are capable of maintaining stable performance over wider temperature ranges. Depending on the type of film used, the capacitors can use PPS (Polyphenylene Sulfide), Polyester, and Polypropylene. Compared to electrolytic capacitors, film capacitors have better temperature stability and high-frequency performance, with low ESR (Equivalent Series Resistance) values and low Df (Dissipation Factor). ECW-H12223JVB is a film capacitor with various application fields and working principles.

ECW-H12223JVB is a film capacitor manufactured by Panasonic. It is a 4-pin radial package capacitor with a rated voltage of 400V, a capacity of 22μF, and a resonance frequency of 40kHz. This capacitor has good capacitance stability over a wide temperature range (-25 to +85 degrees Celsius) and ripple current performance, with insulation performance of 2000VAC (50/60Hz). It also has excellent oxidation-resistance performance and is suitable for applications that involve large surge voltages. It is generally used in feedback circuits of switching power supplies, power amplifiers, and lighting ballasts, as well as a variety of other industrial applications.

ECW-H12223JVB is a type of film capacitor, which is composed of several dielectric layers, electrode layers, and insulation layers. The electrode layers are made of metal foil, which are insulated from each other by insulating layers. When an alternating current is applied, the electric field between the dielectric layers causes intermittent storage and release of electrical charge, resulting in the capacitor storing and releasing energy in a cyclical fashion.Due to the structure of the film capacitor, the circuitry within the capacitor is extremely compact. This allows the capacitor to produce a high capacitance value within a physically small package. Additionally, the film within the capacitor does not react to temperature changes as much as other types of capacitors, allowing it to maintain a stable capacitance rating over a wide temperature range.

ECW-H12223JVB is advantageous due to its high ripple current performance and good insulation performance, allowing it to work in circuits with high surge voltages. Additionally, the wide temperature range (-25 to +85 degrees Celsius) leads to a great degree of temperature stability, allowing the capacitor to maintain its performance in a variety of environments. Finally, its small size and high capacitance value make it highly suitable for a variety of industrial applications.

ECW-H12223JVB is suitable for a variety of applications, such as in feedback circuits of switching power supplies, power amplifiers, and lighting ballasts. It is also generally used in rectifier circuits, voltage-dividing circuits, and as bypass capacitors for oscillators.
