PCR1J181MCL1GS

The PCR1J181MCL1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon’s PCR series. It delivers 180 µF at a 63 V rating with low equivalent series resistance (ESR) and high ripple-current capability for demanding power applications.

This part is designed for high-temperature and high-reliability environments with an operating range of −55 °C to 125 °C and a rated endurance of 4000 hours at 125 °C. Status: Under Development.

Key Features

• Dielectric / Core  The PCR conductive polymer aluminum solid electrolytic construction provides solid-electrolyte performance and stable characteristics over temperature.
• Capacitance & Tolerance  180 µF nominal capacitance with tolerance −20% to +20% (measured at 120 Hz, 20 °C).
• Rated Voltage  63 V DC nominal rating suitable for higher-voltage rail decoupling and bulk applications.
• Low Loss / Dissipation  tan δ = 0.08 (20 °C, 120 Hz), supporting low-loss operation in AC and switching environments.
• Low ESR & High Ripple Current  ESR = 15 mΩ (20 °C, 100 kHz); ripple current handling of 1.75 A at 120 Hz and 3.5 A at 100 kHz.
• Temperature & Endurance  Rated operating range −55 °C to +125 °C with endurance specified at 4000 hours at 125 °C.
• Package & Mounting  Surface-mount radial can (φ10 × 16 L; L: 1.6 × D: 1.0 cm) designed for SMD assembly; surface-mount land size L: 1.03 × W: 1.03 cm; supplied in embossed carrier taping with moisture-proof packing.
• Assembly Compatibility  SMD type compatible with lead-free reflow soldering conditions—peak temperature up to 260 °C as specified for the PCR series.
• Compliance & Qualification  RoHS compliant; the PCR series is noted as AEC-Q200 qualified.
• Polarization  Polarized capacitor suitable for DC power rails.

Typical Applications

• Automotive power electronics  Bulk smoothing and decoupling on 12 V/24 V rails and DC-DC converter outputs where AEC-Q200 qualification and high ripple handling are required.
• Point-of-load DC-DC converters  Output filtering and energy buffering in compact, high-frequency converters benefiting from low ESR and high-frequency ripple capability.
• Industrial drives and controls  Energy storage and decoupling in motor drives and power control modules operating at elevated temperatures.
• Telecom and power modules  Smoothing and decoupling in high-density power modules where small footprint and high ripple current capability matter.

Unique Advantages

• High ripple tolerance: 3.5 A at 100 kHz and 1.75 A at 120 Hz reduce thermal stress in high-frequency switching supplies.
• Very low ESR: 15 mΩ at 100 kHz lowers conduction losses and improves transient response on power rails.
• Wide temperature capability: −55 °C to 125 °C operation and 4000-hour endurance at 125 °C provide long-term stability in hot environments.
• Reflow-compatible SMD form: Compact φ10 × 16 L can in embossed carrier taping supports automated placement and lead‑free assembly up to 260 °C peak.
• Industry qualification: AEC-Q200 designation and RoHS compliance support deployment in regulated and reliability-focused designs.
• Stable loss characteristics: Low tan δ (0.08 at 20 °C, 120 Hz) supports efficient operation across the specified frequency and temperature ranges.
