Summary

# Electrical Characteristics of Metallized Polyester Film Capacitors

## Temperature and Frequency Dependence:

The provided data offers insights into the electrical behavior of metallized polyester film capacitors across various temperature and frequency ranges. Three series are compared: 250VDC, 400VDC, and 630VDC.

Temperature Characteristics:
- Capacitance change (%) and dissipation factor (%) vary with temperature.
- As temperature increases, capacitance may decrease or remain relatively stable, while the dissipation factor often rises.
- Extreme temperatures (-60°C to 100°C) significantly impact these parameters.

Frequency Characteristics:
- Impedance (ohm), capacitance (farads), and dissipation factor (%) change with frequency.
- At higher frequencies (up to 10^13 Hz), the behavior becomes more pronounced, with potential shifts in these parameters.

## Series-Specific Observations:

ECQE(F) Type 250VDC Series:
- Capacitance values range from 0.01µF to 10µF.
- At 1kHz and 100V, temperature effects are evident, with capacitance change (%) and dissipation factor (%) varying accordingly.

ECQE(F) Type 400VDC Series:
- Features 2.2µF, 1.0µF, and 0.1µF capacitance values.
- Similar temperature-dependent behavior to the 250V series, with notable changes at extreme temperatures.

ECQE(F) Type 630VDC Series:
- Also exhibits 2.2µF, 1.0µF, and 0.1µF capacitance values.
- Temperature and frequency have significant impacts on its electrical characteristics, as indicated by the data for each parameter.

Description

This table presents typical electrical characteristics of a metallized polyester film capacitor series, including temperature and frequency-dependent data such as capacitance, dissipation factor, insulation resistance, and impedance across various values (0.01µF to 10µF). It provides performance metrics at different temperatures (-60°C to 100°C) and frequencies (up to 10 kHz), highlighting the capacitor's behavior under varying conditions.
