PCM1H181MCL1GS

The PCM1H181MCL1GS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a compact SMD radial can package. Engineered for high-temperature, high-reliability environments, it delivers low ESR and high ripple-current capability for demanding power applications.

Designed for automotive and industrial electronics, this part combines 180 µF capacitance at 50 V with an extended operating range and long endurance to support robust power filtering, decoupling, and energy-storage needs.

Key Features

• Core Electricals — 180 µF capacitance with a 50 V rated voltage and ±20% tolerance at 120 Hz, 20°C for predictable energy storage and decoupling.
• Low ESR and High Ripple Handling — Specified ESR of 19 mΩ at 100 kHz and ripple current ratings up to 3.2 A at 100 kHz (1.6 A at 120 Hz), enabling efficient power delivery and reduced losses in switching supplies.
• High-Temperature Endurance — Rated for operation from −55°C to +125°C with a guaranteed lifetime of 8000 hours at 125°C to support long-term performance in hot environments.
• Automotive-Grade Reliability — AEC-Q200 qualified and designed with endurance and damp-heat characteristics meeting strict reliability criteria.
• SMD Package & Reflow Compatibility — Surface-mount radial can (L: 1.27 × D: 1.00 cm) compatible with lead-free reflow soldering (260°C peak) for modern assembly processes.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863) for regulated-product use.

Typical Applications

• Automotive Electronics — Suitable for ECUs and power modules where AEC-Q200 qualification and high-temperature endurance are required.
• Power Supply Filtering — Low ESR and high ripple-current capability make it well suited for smoothing and decoupling in DC–DC converters and switching supplies.
• Rugged Industrial Modules — Compact SMD radial can and wide temperature range support power conditioning in industrial control and instrumentation operating in harsh environments.

Unique Advantages

• Extended High-Temperature Life: 8000 hours at 125°C provides predictable long-term performance in elevated-temperature applications.
• Efficient Power Handling: 19 mΩ ESR at 100 kHz combined with 3.2 A ripple capability reduces losses and supports stable regulator operation.
• Automotive-Grade Qualification: AEC-Q200 qualification supports use in validated automotive and similarly demanding systems.
• Assembly-Friendly SMD Form Factor: Lead-free reflow compatibility (260°C peak) and a compact footprint simplify integration into modern surface-mount production flows.
• Regulatory Compliance: RoHS conformity ensures compatibility with environmental regulations for commercial and industrial product lines.
