RPS1E221MCN1GS

The RPS1E221MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can (φ8×11.7 mm) offering 220 µF capacitance at 25 V. It is designed for general-purpose electronic applications that require low equivalent series resistance and high ripple current handling in a compact SMD package.

Key value propositions include low ESR (18 mΩ at 20°C/100 kHz), high-frequency ripple capability (4.4 A at 300 kHz), a wide operating temperature range (−55°C to +105°C), and a rated endurance of 2000 hours at 105°C, providing reliable performance for demanding power and filtering applications.
