PCH1H220MCL1GS

The PCH1H220MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD can package. It delivers low ESR and high ripple-current capability in a compact surface-mount form factor for demanding operating environments.

Designed for automotive and other high-reliability electronics, the part combines a 22 µF capacitance at 50 V with a wide temperature range and a long endurance rating to support power filtering and decoupling where durable, high-temperature performance is required.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Low ESR & High Ripple — Rated ESR of 50 mΩ at 100 kHz; ripple-current capability of 700 mA at 100 kHz and 350 mA at 120 Hz for robust power-handling.
• High-Temperature Endurance — Rated lifetime of 4000 hours at 135 °C, with category temperature range of −55 °C to +135 °C.
• Automotive Qualification — AEC-Q200 qualified to support automotive and other high-reliability system requirements.
• SMD, Lead-Free Reflow Compatible — Chip-type SMD in a radial can package designed for lead-free reflow with a 260 °C peak soldering profile.
• Package & Mounting — Surface-mount radial can (SMD) with dimensions L: 6 × D: 6.3 mm and recommended land size L: 6.6 × W: 6.6 mm.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Suitable for automotive control modules and subsystems that require AEC-Q200 qualification and high-temperature endurance.
• Power Supply Filtering — Low ESR and high ripple-current ratings make it suitable for bulk decoupling and local filtering in power regulation circuits.
• High-Temperature Electronics — Long life at 135 °C supports use in systems exposed to elevated operating temperatures.
• Compact SMD Designs — Small can package and surface-mount land footprint fit space-constrained PCBs where reliable capacitance is needed.

Unique Advantages

• Long High-Temperature Life: 4000 hours at 135 °C provides predictable endurance for designs that operate near elevated temperatures.
• High Ripple Handling: 700 mA at 100 kHz and 350 mA at 120 Hz enable effective suppression of switching and AC ripple in power circuits.
• Low ESR: 50 mΩ at 100 kHz reduces voltage drop and heat generation in high-current applications.
• Automotive-Ready Qualification: AEC-Q200 qualification supports deployment in automotive-grade systems and environments requiring higher reliability.
• Reflow-Compatible SMD Format: Designed for lead-free reflow up to a 260 °C peak, enabling standard surface-mount assembly processes.
• Regulatory Compliance: RoHS conformity supports use in regulated product lines and simplifies compliance planning.
