PCH1E221MCL1GS

The PCH1E221MCL1GS is a chip-type conductive polymer aluminum solid electrolytic capacitor from Nichicon’s PCH series. Designed for surface-mount assembly, it delivers 220 µF at 25 V with low ESR and high ripple-current capability for demanding power applications.

Its combination of a wide operating temperature range (−55 °C to 135 °C), long endurance (4000 hours at 135 °C), AEC-Q200 qualification and RoHS compliance makes it suitable for high-reliability applications including automotive and other high-temperature electronics where stable filtering and bulk energy storage are required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Low ESR — 24 mΩ equivalent series resistance measured at 100 kHz, reducing power loss and thermal rise in high-frequency circuits.
• High Ripple Current — Designed for high ripple environments: 900 mA at 120 Hz and 1.8 A at 100 kHz to support switching regulators and power rails.
• Wide Temperature & Long Life — Operates from −55 °C to 135 °C and rated for 4000 hours at 135 °C under rated voltage, supporting prolonged performance in elevated-temperature environments.
• SMD Reflow Compatible — Chip-type SMD package qualified for lead-free reflow with peak soldering temperature up to 260 °C (pre-heat and time limits per datasheet).
• Automotive-Grade Qualification — AEC-Q200 qualified for suitability in automotive and other high-reliability systems.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Compact Package — Small footprint (approx. L: 0.8 × D: 1.0 cm) and surface-mount land size guidance (L: 1.03 × W: 1.03 cm) for space-constrained designs.

Typical Applications

• Automotive Electronic Control Units (ECUs) — Bulk decoupling and smoothing on 25 V power rails where AEC-Q200 qualification and high-temperature endurance are required.
• DC–DC Converters and Power Rails — Output filter capacitor for switching regulators, leveraging low ESR and high ripple-current capability to improve efficiency and stability.
• Power Modules and Motor Drives — Local energy reservoir and ripple suppression in inverter and motor-control circuitry operating at elevated temperatures.
• Infotainment and Telematics Power — Stable smoothing for on-board electronics that demand compact SMD packaging and reliable performance across wide temperature ranges.

Unique Advantages

• Reduced thermal loss: Low ESR (24 mΩ at 100 kHz) minimizes dissipation in high-frequency switching environments.
• Handles high ripple: Specified ripple currents (900 mA at 120 Hz, 1.8 A at 100 kHz) accommodate the demands of modern power converters.
• High-temperature endurance: Rated life of 4000 hours at 135 °C provides predictable aging and reliability for harsh-environment designs.
• Automotive-ready qualification: AEC-Q200 qualification supports use in vehicle systems and other high-reliability applications.
• Reflow-friendly SMD: Chip-type SMD construction with compatibility for lead-free reflow up to 260 °C simplifies automated assembly.
• Compact footprint: Small case dimensions and defined land pattern information enable dense PCB layouts without sacrificing capacitance.
