PCG0E221MCL1GS

The PCG0E221MCL1GS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a chip-type surface-mount package. It delivers 220 µF capacitance at a 2.5 V rating with a compact φ5 × 6 mm footprint and is offered as part of the PCG series for higher-capacitance SMD solutions.

Designed for demanding environments, this part combines low ESR and high ripple-current capability with an endurance rating at elevated temperature, targeting applications where compact bulk capacitance and robust performance are required, including automotive use (AEC-Q200).

Key Features

• Capacitance & tolerance — 220 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C for predictable bulk energy storage.
• Rated voltage — 2.5 V nominal voltage suitable for low-voltage power rails.
• Low ESR and high ripple handling — ESR of 30 mΩ at 20°C/100 kHz, with ripple-current ratings of 1.05 A at 120 Hz and 2.1 A at 100 kHz to support high-frequency converter outputs and decoupling.
• Leakage current — Specified leakage current of 110 µA after voltage application, enabling predictable standby and bias behavior.
• Temperature and endurance — Operates from −55°C to +105°C with a rated endurance of 2000 hours at 105°C under rated voltage.
• Automotive-grade qualification — AEC-Q200 rating and explicit application listing for automotive use.
• Compact SMD package — Chip-type radial can for surface mount, size φ5 × 6 L (L: 6 × D: 5 mm); supplied in embossed carrier taping with moisture-proof packing for assembly.
• Polarized, chip-type form factor — Polar construction for designs requiring electrolytic bulk capacitance in a small board area.

Typical Applications

• Automotive power modules — Bulk decoupling and smoothing on low-voltage rails where 2.5 V operation and AEC-Q200 qualification are required.
• DC–DC converter outputs — Low ESR (30 mΩ) and high 100 kHz ripple-current rating (2.1 A) support stabilization of switching regulator outputs.
• Infotainment and telematics — Compact SMD footprint and high capacitance for local energy buffering in space-constrained board areas.
• Backup and hold-up capacitors — High capacitance in a small package with controlled leakage for short-term hold-up or power-path smoothing.

Unique Advantages

• High capacitance in a small SMD package: 220 µF in a φ5 × 6 mm can reduces board area compared with larger discrete options.
• High-frequency performance: 30 mΩ ESR at 100 kHz and a 2.1 A high-frequency ripple-current rating enable reliable filtering of switching noise.
• Temperature and endurance assurance: −55°C to +105°C operation and 2000 hours endurance at 105°C provide predictable lifetime under elevated temperature stress.
• Automotive-grade qualification: AEC-Q200 rating and explicit automotive application listing support use in vehicle systems.
• Production-friendly packaging: Embossed carrier taping with moisture-proof packing facilitates automated surface-mount assembly and handling.
