Low Impedance Radial Aluminum Electrolytic Capacitors for Switching Power Supplies

Overview

The CD287 series is a radial aluminum electrolytic capacitor designed for switching power supply applications requiring low impedance and extended service life.
Its 105°C operating temperature rating and ripple current capability support stable operation in high load conditions.

Key Electrical and Reliability Features

• Operating temperature: 105°C
• Load life: 5000 hours at 105°C
• Low impedance structure
• High ripple current capability
• Radial leaded package for through-hole mounting

Performance in Power Conversion Circuits

Switching power supplies require capacitors with low impedance to reduce output ripple and improve transient response.
High ripple current tolerance and thermal endurance are essential for long-term reliability in continuous operation.

Applications

• Switching mode power supplies
• Output filtering in DC power modules
• Industrial power control systems
• General high ripple current circuits

Design Considerations

• Match ripple current rating with converter operating conditions
• Provide adequate PCB thermal dissipation
• Select voltage rating with derating margin
• Consider impedance characteristics for switching frequency
