Features and Applications
The CLS20A metalized polycarbonate film dielectric DC fixed capacitor uses polycarbonate film as the dielectric, and aluminum is deposited on the film as the electrode by vacuum evaporation method. It is wrapped with polyester heat-resistant tape, sealed with epoxy resin, and axially led out.
Small size, light weight, high temperature resistance, high insulation resistance, self-healing performance.
CLS20A metalized polycarbonate film dielectric DC fixed capacitor is used for logic control, delay, integration, filtering, coupling, and phase shifting circuits in precision instruments, meters, and other electronic devices.
