PCM1H121MCL2GS

The PCM1H121MCL2GS is a conductive polymer aluminum solid electrolytic chip capacitor in a surface-mount can package. It delivers 120 µF at 50 V with low equivalent series resistance and rated high ripple current, engineered for applications that require stable capacitance and thermal endurance.

This part targets demanding electronic power designs and automotive applications, offering long-term reliability with an 8000-hour rated life at 125°C, AEC‑Q200 qualification, and lead‑free reflow compatibility up to a 260°C peak.

Key Features

• Capacitance & Voltage — 120 µF rated capacitance at 50 V with ±20% tolerance, suitable for bulk decoupling and energy storage in power circuits.
• Low ESR — 25 mΩ equivalent series resistance measured at 100 kHz, enabling lower loss and improved transient response in high-frequency power paths.
• High Ripple Current — Supports up to 2.5 A at 100 kHz and 1.25 A at 120 Hz, allowing sustained AC stress handling in switching power applications.
• Extended High‑Temperature Life — Long life rating of 8000 hours at 125°C; endurance specifications include capacitance change within ±20% and ESR within 200% of initial values after endurance testing.
• Wide Operating Temperature Range — Rated from −55°C to +125°C for reliable performance across harsh thermal environments.
• Manufacturing & Assembly Compatibility — Chip-type SMD with lead‑free reflow soldering compliance to 260°C peak (reflow up to two times), and a recommended land pattern of 8.3 × 8.3 mm.
• Automotive-Grade Qualification — AEC‑Q200 qualified for use in designs requiring industry-recognized component stress testing and qualification.
• Regulatory Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Suited for automotive systems that require AEC‑Q200 qualification and long-term operation at elevated temperatures.
• Power Supply Filtering and Decoupling — Low ESR and high ripple current capability make it appropriate for smoothing and decoupling in DC‑DC converters and switching regulators.
• Surface‑Mount Power Modules — Chip SMD form factor and lead‑free reflow compatibility simplify integration into modern SMT power assemblies.

Unique Advantages

• High thermal endurance: 8000 hours at 125°C provides predictable lifetime performance in high-temperature environments.
• Low-loss operation: 25 mΩ ESR at 100 kHz reduces dissipation and supports efficient power conversion and transient suppression.
