PCH1D151MCL4GS

The PCH1D151MCL4GS is a conductive polymer aluminum solid electrolytic chip capacitor designed for demanding electronic power applications. As an SMD, low-ESR capacitor with high ripple current capability and AEC-Q200 qualification, it is targeted at automotive and high-temperature electronics where long-term reliability and thermal endurance are required.

Key value propositions include low equivalent series resistance (25 mΩ at 100 kHz), high ripple handling (up to 1.2 A at 100 kHz), and long life at elevated temperature (4000 hours at 135°C), making it suitable for compact surface-mount power circuits that must operate across wide temperature ranges.

Key Features

• Capacitance and Voltage: 150 µF rated at 20 V with ±20% tolerance, providing bulk decoupling and energy storage for power rails.
• Low ESR & High Ripple Current: ESR of 25 mΩ at 100 kHz and ripple current ratings of 1.2 A at 100 kHz and 600 mA at 120 Hz support high-frequency switching supplies and power conversion stages.
• High Temperature Endurance: Specified operating temperature range of -55°C to 135°C and a rated lifetime of 4000 hours at 135°C for extended operation in hot environments.
• Reliability & Qualification: AEC-Q200 qualified and compliant with RoHS (2011/65/EU, (EU)2015/863); ESR measured after endurance at -40°C to ensure low-temperature performance retention.
• Assembly Compatibility: SMD can-type package with peak lead‑free reflow compatibility to 260°C, supporting common surface-mount assembly processes.
• Compact Package: Case dimensions L: 8 × D: 6.3 mm with recommended land size 6.6 × 6.6 mm for dense PCB layouts.

Typical Applications

• Automotive Power Electronics: Use for DC‑DC converters, power rails and transient suppression in automotive control modules, leveraging AEC‑Q200 qualification and 135°C endurance.
• Industrial Power Supplies: Bulk decoupling and output filtering in compact, high-temperature industrial converters where low ESR and high ripple current are required.
• Embedded Systems and Control Units: Local energy storage and smoothing on compact SMD boards that demand high reliability over wide temperature ranges.

Unique Advantages

• Long High‑Temperature Life: Rated for 4000 hours at 135°C, enabling prolonged operation in elevated-temperature environments.
• Superior High‑Frequency Performance: 25 mΩ ESR at 100 kHz and specified ESR after endurance testing support stable operation in high-frequency switching circuits.
• High Ripple Handling: Ripple current ratings up to 1.2 A at 100 kHz reduce heating and extend system reliability under heavy dynamic loads.
• AEC‑Q200 Qualification: Formal qualification for demanding applications provides confidence for automotive and similarly rigorous system designs.
• Surface-Mount Convenience: Can-type SMD footprint with lead‑free reflow compatibility streamlines automated assembly for compact PCBs.
• Wide Operating Range: −55°C to +135°C rating supports systems that experience broad temperature swings.
