Panasonic EE-A Radial Electrolytic Capacitor, 22µF 450V, 10000h @ 105°C

The Panasonic EE-A Series EEUEE2W220S is a high-performance radial leaded aluminium electrolytic capacitor engineered for demanding applications requiring long-term reliability and robust operation. This component is defined by its impressive 10000-hour endurance rating at the maximum category temperature of +105°C, ensuring consistent performance in challenging thermal environments.

A standout feature of this series is its exceptional high-frequency ripple current handling, which is 40% higher than the standard ED series. With a rated ripple current of 945mA, it is ideally suited for power supply filtering and smoothing circuits where low equivalent series resistance (ESR) and high stability are critical.

Key Specifications & Construction

This capacitor offers a capacitance of 22µF with a tolerance of ±20% and a high 450V DC working voltage, making it a durable choice for high-voltage circuits. Its polar design is housed in a compact radial case with dimensions of 16mm in body diameter and 20mm in body length, featuring a standard 7.5mm lead spacing for easy board mounting.

Constructed with high-quality materials, it maintains a very low maximum leakage current of 604µA. The component operates reliably across a broad temperature range from -25°C to +105°C, providing versatility for various industrial and commercial electronic designs.

Applications

The combination of high voltage rating, extended lifespan, and superior ripple current performance makes this capacitor an excellent choice for switch-mode power supplies (SMPS), inverters, motor drives, and other power electronics where durability and efficiency are paramount. Its robust build and proven reliability from the Panasonic EE-A series offer peace of mind for critical circuit designs.
