PCH1D471MCL1GS

The PCH1D471MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor from Nichicon’s PCH series, designed for surface-mount assemblies. It delivers 470 µF at 20 V with low ESR and high ripple handling in a compact φ8 × 12 mm can‑style SMD package.

Targeted at demanding environments, this part combines AEC‑Q200 qualification, a wide operating temperature range (‑55 °C to 135 °C) and a 4000‑hour endurance at 135 °C, making it suitable for automotive and high‑temperature power applications that require stable capacitance and robust thermal performance.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance with a rated voltage of 20 V and tolerance ±20%, suitable for bulk decoupling and energy storage in compact assemblies.
• Low ESR & High Ripple Capability: ESR of 18 mΩ measured at 20 °C / 100 kHz supports high frequency filtering; rated ripple currents of 1.25 A at 120 Hz and 2.5 A at 100 kHz enable effective smoothing in power stages.
• High Temperature Endurance: Qualified for continuous operation from ‑55 °C to 135 °C and specified for 4000 hours at 135 °C, supporting long‑life operation in elevated ambient temperatures.
• Reliability & Leakage: Low leakage current (specified 282 µA) and lifecycle characteristics governed by endurance and shelf‑life tests for predictable long‑term behavior.
• Surface-Mount, Reflow Compatible: Chip type can (radial, SMD) designed for surface-mount assembly with reflow compatibility up to specified soldering profiles.
• Automotive-Grade Qualification: AEC‑Q200 rated, indicating suitability for automotive electronic applications that require component qualification.
• Packaging & Handling: Supplied in embossed carrier tape with moisture‑proof packing and released into mass production for immediate production use.

Typical Applications

• Automotive Power Electronics: Bulk decoupling and smoothing in automotive ECUs and power modules where AEC‑Q200 qualification and 135 °C endurance are required.
• DC–DC Converters & Power Regulation: Output and input filtering in converters that demand low ESR and high ripple current capability at high frequency.
• High‑Temperature Industrial Power Supplies: Energy storage and ripple suppression in industrial systems operating across wide temperature ranges up to 135 °C.

Unique Advantages

• Stable high‑temperature operation: 4000 hours endurance at 135 °C provides predictable capacitance and ESR stability for long service life in hot environments.
• High ripple and low loss: Low ESR (18 mΩ @100 kHz) combined with specified ripple currents reduces thermal stress and improves power stage efficiency.
• Automotive readiness: AEC‑Q200 qualification supports use in automotive electronics and other applications that require qualified components.
• Compact SMD form factor: φ8 × 12 mm can‑style SMD package allows substitution of larger radial caps with surface‑mount assembly benefits.
• Production-ready packaging: Embossed carrier tape and moisture‑proof packing facilitate high-volume pick‑and‑place assembly and storage.
