High Frequency Low Impedance Radial Aluminum Electrolytic Capacitors for Switching Power Supplies

Overview

The CD286 series is a radial aluminum electrolytic capacitor designed for switching power supply circuits requiring low impedance and stable ripple filtering.
Its 105°C temperature rating and defined load life support reliable operation in high frequency power conversion environments.

Key Electrical and Reliability Features

• Operating temperature: 105°C
• Load life: 2000 hours at 105°C
• Low impedance structure for high frequency operation
• Radial leaded package for through-hole assembly

Role in Power Conversion Circuits

In switching regulators, low impedance capacitors reduce output voltage ripple and improve transient response.
Thermal endurance and stable electrical characteristics are required for continuous operation under ripple current stress.

Applications

• Switching mode power supplies
• DC output filtering stages
• Industrial power modules
• General high frequency power circuits

Design Considerations

• Match ripple current capability with converter operating conditions
• Apply voltage derating for reliability
• Provide adequate thermal dissipation on PCB
• Select impedance characteristics suitable for switching frequency
