PCG0G221MCL1GS

The PCG0G221MCL1GS is a conductive polymer aluminum solid electrolytic capacitor in a chip-style surface-mount can, offering 220 µF capacitance at a 4 V rating. It is designed for compact power and decoupling applications that require high capacitance, low ESR and robust thermal endurance.

With an operational range from -55 °C to 105 °C and AEC-Q200 rating, this part targets demanding embedded and automotive-grade power designs where ripple handling and long-term stability are critical.

Key Features

• Capacitance & Tolerance — 220 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20 °C).
• Rated Voltage — 4 V DC rating suitable for low-voltage power rails.
• Low ESR & High Ripple Capability — ESR of 32 mΩ measured at 100 kHz (20 °C), with low-frequency ripple current of 1 A (120 Hz) and high-frequency ripple current of 2 A (100 kHz), enabling effective smoothing and decoupling at both LF and HF.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.12, supporting efficient AC performance.
• Leakage & Endurance — Leakage current up to 300 µA and endurance rated 2000 hours at 105 °C with defined limits on capacitance change, tan δ and ESR after endurance stress.
• Temperature & Reliability — Wide operating temperature range from -55 °C to 105 °C and qualified to AEC-Q200.
• Compact SMD Package — Chip-type can in a compact φ5 × 6 mm form factor (L: 6 × D: 5 mm) for space-constrained PCBs; surface-mount package with embossed carrier taping and moisture-proof packing for automated assembly.

Typical Applications

• Automotive power rails — Bulk and decoupling on low-voltage rails in automotive control modules and electronics leveraging the AEC-Q200 rating and wide temperature range.
• DC–DC converters — Input/output smoothing and ripple suppression where low ESR and high ripple current handling improve converter stability and thermal performance.
• Point-of-load decoupling — Local energy storage for processors, power management ICs and sensors requiring compact, high-capacitance SMD components.
• Industrial embedded systems — Power conditioning in control and monitoring equipment exposed to extended temperature ranges and long duty cycles.

Unique Advantages

• High capacitance in a small footprint: 220 µF in a φ5 × 6 mm chip reduces board area while providing substantial energy storage for low-voltage rails.
• Low ESR for improved transient response: 32 mΩ at 100 kHz lowers voltage ripple and dissipative losses, enhancing converter and regulator performance.
• High ripple-current capability: Rated for 1 A at 120 Hz and 2 A at 100 kHz to handle both low- and high-frequency ripple demands.
• Automotive-grade qualification: AEC-Q200 rating and -55 °C to 105 °C operation support demanding environments and reliability-focused designs.
• Durability under stress: 2000-hour endurance at 105 °C with controlled limits on capacitance, tan δ and ESR preserves long-term performance.
• Assembly-ready packaging: Supplied in embossed carrier tape with moisture-proof packing for efficient SMT assembly and handling.
