PCR1H121MCL2GS

The PCR1H121MCL2GS is a conductive polymer aluminum solid electrolytic surface-mount capacitor from Nichicon’s PCR series. Designed for high-reliability applications, it delivers low ESR and high ripple-current capability in a compact SMD can package.

Targeted at demanding electronics that require sustained performance at elevated temperatures, this part is qualified to AEC‑Q200, rated for operation from -55°C to 125°C, and engineered for long life and lead‑free reflow compatibility.

Key Features

• Electrical Performance — 120 µF nominal capacitance at 50 V rated voltage with ±20% tolerance for stable bulk capacitance in power stages and decoupling networks.
• Low ESR — 25 mΩ ESR specified at 100 kHz, 20°C, supporting efficient high-frequency decoupling and reduced thermal loss.
• High Ripple Current — 1.45 A at 120 Hz and 2.9 A at 100 kHz, enabling higher AC stress capability in switching and power conversion circuits.
• High-Temperature Endurance — Rated lifetime of 4000 hours at 125°C with documented endurance characteristics; ESR after endurance is specified at -40°C.
• Wide Operating Temperature — Specified for operation from -55°C to 125°C for reliable performance across harsh thermal environments.
• SMD Package & Reflow Compatibility — Surface-mount radial can package designed for lead‑free reflow soldering with a 260°C peak profile compliance.
• Automotive-Grade Qualification — AEC‑Q200 qualified for use in applications requiring that level of component qualification.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Mechanical Footprint — Compact dimensions (L: 1.2 × D: 0.8 cm) with a recommended PCB land pattern of 8.3 × 8.3 mm for dense board layouts.

Typical Applications

• Automotive electronics — For in‑vehicle systems that require AEC‑Q200 qualified components with sustained performance at elevated temperatures.
• Power conversion and DC‑DC modules — Low ESR and high ripple current support smoothing and decoupling in switching regulators and power stages.
• Industrial and ruggedized equipment — Long life at 125°C and wide temperature range suit sustained operation in harsh thermal environments.

Unique Advantages

• Proven high-temperature endurance: 4000 hours at 125°C provides predictable lifetime behavior in elevated-temperature designs.
• High-frequency performance: 25 mΩ ESR at 100 kHz and 2.9 A ripple capability reduce losses and improve stability in high-speed switching circuits.
• SMD reflow readiness: Lead‑free reflow compatibility to 260°C simplifies assembly for modern surface-mount processes.
• Automotive-grade qualification: AEC‑Q200 status supports selection for qualified automotive and similarly demanding applications.
• Compact can package: Small footprint and standardized land pattern enable space-efficient placement on congested PCBs.
