PCG1A181MCL1GS

The PCG1A181MCL1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s PCG series, offering 180 µF capacitance at a 10 V rating. Engineered for applications that require compact, high-capacitance SMD components, it delivers low ESR and elevated ripple-handling capability in a small φ6.3 × 6L package.

With AEC-Q200 rating and a -55 °C to +105 °C operating range, this capacitor targets demanding electronic designs that need reliable power smoothing, decoupling and hold-up performance across wide temperature and endurance conditions.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a rated voltage of 10 V and tolerance ±20% (120 Hz, 20 °C).
• Conductive Polymer Electrolyte — Solid polymer construction for stable electrical characteristics and reduced ESR compared to traditional wet electrolytics.
• Low ESR — ESR specified at 25 mΩ (measured at 20 °C, 100 kHz), improving efficiency in high-frequency power paths.
• High Ripple Current Capability — Low-frequency ripple current 1.3 A (120 Hz) and high-frequency ripple current 2.6 A (100 kHz) for effective filtering and converter output stabilization.
• Loss Tangent (tan δ) — tan δ = 0.12 (measured at 20 °C, 120 Hz, 10 V) to characterize dielectric loss under typical conditions.
• Leakage and Endurance — Leakage current 360 µA (after 2 minutes at rated voltage, 20 °C) and 2000 h endurance at 105 °C with defined performance retention criteria.
• Automotive-Grade Reliability — AEC-Q200 rated; suitable for designs requiring automotive-level component screening.
• Compact SMD Package & Packaging — Radial, can-style SMD: φ6.3 × 6L size with surface-mount land size 6.6 × 6.6 mm; supplied in embossed carrier taping with moisture-proof packing for automated assembly. Status: Mass production.

Typical Applications

• Automotive power electronics — Bulk and decoupling for control modules and power rails where AEC-Q200 qualification and wide temperature range are required.
• DC–DC converter output filtering — Low ESR and high ripple-current capability help stabilize converter outputs and reduce voltage ripple at high switching frequencies.
• Power-supply decoupling — Compact SMD footprint provides high capacitance for board-level decoupling of processors, sensors and analog front-ends.
• Backup and hold-up circuits — 180 µF capacitance combined with solid-polymer reliability supports short-term hold-up in small form-factor designs.

Unique Advantages

• High capacitance in a small SMD can — 180 µF in a φ6.3 × 6L package reduces PCB area for equivalent capacitance compared with larger components.
• Improved thermal and frequency performance — ESR of 25 mΩ at 100 kHz and high-frequency ripple rating of 2.6 A support efficient operation in switching power stages.
• Automotive-grade screening — AEC-Q200 rating aligns the part with designs requiring automotive qualification processes and traceability.
• Long endurance at elevated temperature — Specified 2000 hours at 105 °C with defined limits on capacitance change, tan δ and ESR for predictable long-term behavior.
• Assembly-ready packaging — Embossed carrier taping and moisture-proof packing minimize handling risk and streamline pick-and-place processes.
