PCH1K270MCL1GS

The PCH1K270MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor from Nichicon's PCH series. It delivers a 27 µF capacitance at a rated voltage of 80 V in a compact surface-mount radial can package designed for demanding thermal and electrical environments.

Engineered for high-voltage, high-temperature applications, this capacitor combines low ESR (38 mΩ at 100 kHz), high ripple-current capability, and a long endurance rating of 4000 hours at 135°C. AEC-Q200 qualification and RoHS compliance make it suitable for rigorous, reliability-focused designs.

Key Features

• Core Type Conductive polymer aluminum solid electrolytic, chip (SMD) construction for high capacitance in a compact footprint.
• Electrical Performance 27 µF capacitance, 80 V rated voltage, and low ESR of 38 mΩ (measured at 100 kHz, 20°C) for efficient filtering and low loss.
• Ripple Current High ripple capability: 500 mA at 120 Hz and 1 A at 100 kHz to support power conversion and switching applications.
• Temperature and Lifetime Wide operating range of −55°C to +135°C with a rated endurance of 4000 hours at 135°C; ESR specified after endurance and at −40°C.
• Reliability & Qualification AEC-Q200 qualified for demanding environments; endurance, damp heat and shelf-life specifications are defined in the series datasheet.
• Assembly Compatibility Surface-mount radial can package designed for lead-free reflow soldering with peak temperature up to 260°C (reflow conditions per datasheet).
• Compliance RoHS compliant (2011/65/EU, (EU)2015/863).
• Package & Footprint Compact size: L 1.0 cm × D 0.8 cm; recommended land pattern L 8.3 mm × W 8.3 mm for PCB layout.

Typical Applications

• Automotive Electronics Suited to automotive control modules and power electronics where AEC-Q200 qualification and wide temperature capability are required.
• High-Voltage Power Rails Filtering and decoupling on higher-voltage distribution lines (up to 80 V) where low ESR and high ripple-current handling reduce losses and temperature rise.
• Power Conversion Energy storage and smoothing in DC–DC converters and switching regulators that demand compact, high-capacitance components with strong endurance at elevated temperatures.
• Industrial High-Temperature Electronics Applications that require reliable operation at elevated ambient temperatures, leveraging the 4000-hour life rating at 135°C.

Unique Advantages

• High voltage handling: 80 V rated voltage enables use on higher-voltage rails without oversized components.
• Low ESR for efficient filtering: 38 mΩ at 100 kHz reduces conduction losses and improves transient response in power circuits.
• High ripple-current capability: 1 A at 100 kHz (and 500 mA at 120 Hz) supports demanding switching applications and reduces thermal stress.
• Extended high-temperature life: 4000 hours at 135°C provides long-term stability for designs exposed to sustained elevated temperatures.
• AEC-Q200 qualified: Enables use in reliability-focused systems, including automotive-grade electronics.
• Reflow-compatible SMD package: Designed for lead-free reflow up to 260°C peak to integrate into modern assembly processes.
