PCH1H121MCL1GS

The PCH1H121MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor from Nichicon's PCH series. It delivers 120 µF capacitance at a 50 V rating in a compact surface-mount can package designed for high-temperature operation and long-term reliability.

Engineered for demanding electronics, this part combines low ESR (25 mΩ at 100 kHz), high ripple-current capability, and a wide operating range (−55 °C to 135 °C) with AEC‑Q200 qualification and RoHS compliance for use in robust industrial and automotive designs.

Key Features

• Dielectric and Construction: Conductive polymer aluminum solid electrolytic design providing stable capacitance with polarized operation for high-capacity SMD applications.
• Electrical Performance: 120 µF capacitance at 50 V with low ESR of 25 mΩ (100 kHz) and high ripple-current capability (2.1 A at 100 kHz; 1.05 A at 120 Hz), supporting effective smoothing and decoupling in power circuits.
• Thermal and Lifetime Characteristics: Rated to operate from −55 °C to 135 °C with a long endurance specification of 4000 hours at 135 °C, enabling extended service life in elevated-temperature environments.
• Package and Assembly: Chip-type SMD radial can (1 cm × 1 cm footprint) optimized for lead‑free reflow processes with a peak soldering temperature compatibility up to 260 °C.
• Standards and Reliability: AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting qualification requirements for automotive and other high-reliability markets.

Typical Applications

• Automotive electronics: Suitable for control modules and power subsystems where AEC‑Q200 qualification, wide temperature range, and long life at elevated temperature are required.
• Power supply filtering and bulk decoupling: Low ESR and high ripple-current ratings make this capacitor effective for smoothing and energy storage in DC–DC converters and power rails.
• Industrial power electronics: Designed for high-temperature environments and continuous operation, supporting robust performance in industrial converters and motor drives.

Unique Advantages

• High-temperature endurance: 4000 hours at 135 °C provides predictable aging and longevity for designs exposed to sustained elevated temperatures.
• Low ESR for improved efficiency: 25 mΩ ESR at 100 kHz reduces losses and heat generation in high-frequency power applications.
• High ripple-current capability: 2.1 A at 100 kHz and 1.05 A at 120 Hz support demanding transient and continuous ripple conditions in power circuits.
• AEC‑Q200 qualification: Explicit qualification aligns the part with automotive reliability requirements for use in vehicle electrical systems.
• Surface-mount convenience: Chip-type can package and compatibility with lead‑free reflow up to 260 °C simplify assembly for modern SMT production flows.
• Regulatory compliance: RoHS conformity ensures compatibility with environmental regulatory requirements.
