PCR1H121MCL1GS

The PCR1H121MCL1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 120 µF capacitance at a 50 V rating. It combines low ESR and high ripple-current capability in a compact φ10 × 10 mm SMD package.

With an extended temperature range of −55°C to +125°C, AEC-Q200 qualification, and a 4000-hour endurance at 125°C, this part is aimed at demanding power-electronics applications that require reliable high-temperature performance and robust ripple handling.

Key Features

• Capacitance & Voltage — 120 µF capacitance, rated for 50 V operation.
• Low Equivalent Series Resistance (ESR) — 25 mΩ measured at 20°C and 100 kHz, enabling lower loss and improved power delivery.
• High Ripple-Current Capability — 1.5 A at 120 Hz (low frequency) and 3.0 A at 100 kHz (high frequency) for effective smoothing in power circuits.
• High-Temperature Endurance — Specified life of 4000 hours at 125°C, supporting sustained operation in elevated-temperature environments.
• Wide Operating Temperature — −55°C to +125°C for use across harsh thermal conditions.
• Low Loss — tan δ (DF) of 0.08 measured at 20°C, 120 Hz for predictable AC behavior.
• Leakage Current — 180 µA leakage current specification.
• Automotive-Grade Qualification — AEC-Q200 rated for use in automotive and similarly demanding applications.
• SMD Packaging & Supply — Chip-type radial can SMD (φ10 × 10 mm), supplied in embossed carrier tape with moisture-proof packing for automated assembly.
• RoHS Compliant — Meets RoHS requirements.

Typical Applications

• Automotive Power Electronics — Suitable for DC link and smoothing functions in automotive systems where AEC‑Q200 qualification and high-temperature endurance are required.
• DC–DC Converters — Low ESR and high ripple-current handling support input/output filtering and bulk decoupling in converter stages.
• Industrial Power Supplies — Designed for high-temperature, high-duty environments found in industrial power modules and control equipment.
• Telecom and Networking Power Modules — Compact SMD form and strong ripple capability help maintain stable supply rails in power-dense systems.

Unique Advantages

• High ripple tolerance: 1.5 A at 120 Hz and 3.0 A at 100 kHz provide robust smoothing for both low- and high-frequency ripple sources.
• Low-loss operation: 25 mΩ ESR and 0.08 tan δ reduce heat generation and improve efficiency in power paths.
• Long-term high-temperature reliability: 4000 hours at 125°C ensures component endurance in sustained elevated-temperature applications.
• Automotive-capable: AEC‑Q200 qualification supports use in vehicle electronics and other high-reliability markets.
• Assembly-ready SMD format: Embossed carrier taping and moisture-proof packing enable efficient automated placement and reflow processing up to the specified profile limits.
