Performance Characteristics

ESR Values

The KZE series offers moderate ESR values appropriate for general-purpose applications while maintaining cost-effectiveness. Typical ESR values depend on capacitance and voltage ratings.

Ripple Current

Provides standard ripple current handling capabilities suitable for most power supply filtering applications.

Leakage Current

Low leakage current values ensure efficient operation and minimal power loss in standby applications.

Mounting

Radial lead construction allows for through-hole mounting with various lead spacing options to accommodate different PCB layouts.

Selection Guide

When selecting capacitors from the KZE series, consider these key parameters:

Voltage Rating Selection

The rated voltage should be at least 1.2x the maximum applied voltage to ensure reliability. For applications with high-voltage transients, consider derating further.

Capacitance Value Selection

Higher capacitance values provide better filtering but may increase inrush current. Balance capacitance with your application requirements and inrush limitations.

Package Size Considerations

The KZE series offers various case sizes to accommodate different space constraints. Consider thermal management when selecting smaller packages.

FAE Note: The KZE series is ideal for general purpose applications where a balance of performance and cost is required. For higher ripple current applications, consider the KY series.
