PCM1H121MCL1GS

The PCM1H121MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD can package designed for high-reliability applications. It delivers low ESR and high ripple-current capability in a compact surface-mount form factor, with a rated capacitance of 120 µF at 50 V and ±20% tolerance.

Engineered for demanding thermal environments, this capacitor supports extended operation up to 125°C and is AEC‑Q200 qualified and RoHS compliant, making it suitable for applications that require long life and stability under elevated temperatures.

Key Features

• Capacitance & Voltage — 120 µF rated capacitance at 50 V with ±20% tolerance for consistent energy storage and decoupling performance.
• Low ESR & High Ripple Handling — 25 mΩ ESR measured at 100 kHz and ripple current ratings of 2.5 A (100 kHz) and 1.25 A (120 Hz) to support high-frequency power stages and load transients.
• Extended High‑Temperature Life — Endurance of 8000 hours at 125°C, providing long-term stability in elevated-temperature environments.
• Wide Operating Temperature Range — Specified from −55°C to +125°C to cover a broad range of ambient and operating conditions.
• Surface-Mount Package — Chip-type SMD can with package dimensions approximately 10 mm × 10 mm and recommended land size L: 10.3 mm × W: 10.3 mm for PCB mounting.
• Lead‑free Reflow Compatible — Compatible with lead‑free reflow soldering (peak up to 260°C) per manufacturer profile, with up to two reflow passes at ≤260°C.
• Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863) for regulated designs.

Typical Applications

• Automotive Electronics — AEC‑Q200 qualification and 8000-hour life at 125°C make this capacitor suitable for use in automotive electronic modules that require long-term temperature endurance.
• Power Conversion & DC–DC Stages — Low ESR (25 mΩ at 100 kHz) and high ripple-current capability support smoothing and decoupling in power converters and regulators.
• High‑Temperature Board Assemblies — Designed for assemblies that undergo lead‑free reflow up to 260°C and operate at elevated temperatures.

Unique Advantages

• Long High‑Temperature Endurance: 8000 hours at 125°C provides predictable lifetime performance for temperature-stressed designs.
• High Ripple and Low Loss: 25 mΩ ESR and 2.5 A ripple rating at 100 kHz reduce thermal stress and improve voltage stability in high-frequency power circuits.
• Automotive‑Grade Reliability: AEC‑Q200 qualification supports use in designs that require automotive-level component validation.
• SMD Convenience with Reflow Compatibility: Chip-type SMD can simplifies PCB assembly and supports lead‑free reflow processes up to a 260°C peak.
• Wide Temperature Range: −55°C to +125°C operating range accommodates harsh ambient conditions and broad deployment scenarios.
