PCH1E221MCL6GS

The PCH1E221MCL6GS is a chip-type conductive polymer aluminum solid electrolytic capacitor designed for surface-mount applications requiring high temperature endurance and low impedance. With a 220 µF capacitance at 25 V, it targets power conditioning and decoupling roles in demanding electronics, including automotive and industrial systems.

Key value comes from a combination of low ESR (20 mΩ at 100 kHz), high ripple current capability, and long-term reliability — specified for 4,000 hours at 135 °C — while supporting lead-free reflow processes and RoHS compliance.

Key Features

• Capacitance and Voltage — 220 µF rated at 25 V with ±20% tolerance, suitable for bulk decoupling and energy storage in compact SMD designs.
• Low ESR and High Ripple Current — ESR of 20 mΩ at 100 kHz and ripple current ratings of 2.3 A at 100 kHz and 1.15 A at 120 Hz, enabling efficient AC and switching-current handling.
• Wide Temperature Range and High-Temperature Life — Rated for operation from −55 °C to +135 °C with an endurance specification of 4000 hours at 135 °C.
• Reliability & Qualification — AEC-Q200 qualified and designed to meet endurance, damp heat and shelf-life requirements with ESR verification after endurance and at −40 °C.
• SMD Package & Assembly — Chip-type, surface-mount package (radial can - SMD) compatible with lead-free reflow soldering up to a 260 °C peak, with recommended land pattern size of 8.3 × 8.3 mm.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863) and specified leakage current and impedance ratios per datasheet requirements.

Typical Applications

• Automotive Power Electronics — Bulk smoothing and decoupling in electronic control modules where AEC-Q200 qualification and high-temperature endurance are required.
• DC‑DC Converters — Input/output filtering and energy buffering for point-of-load regulators benefiting from low ESR and high ripple-current capability.
• Industrial Controls — Power-conditioning and transient suppression in industrial control boards exposed to wide temperature ranges and repeated thermal cycling.
• Telecom and Networking Power Supplies — Local energy storage and noise suppression in regulated power rails where compact SMD parts and high frequency performance matter.

Unique Advantages

• High-temperature endurance: Specified for 4000 hours at 135 °C, providing predictable lifetime behavior in elevated-temperature assemblies.
• Low impedance at high frequency: 20 mΩ ESR at 100 kHz improves AC performance and reduces losses in switching applications.
• Robust ripple handling: Rated ripple currents of 2.3 A (100 kHz) and 1.15 A (120 Hz) support high-duty switching environments without excessive heating.
• SMD-ready with lead-free reflow: Compatible with 260 °C peak lead-free reflow profiles and standard land pattern recommendations for streamlined assembly.
• Industry qualification: AEC-Q200 qualification and RoHS compliance help meet regulatory and reliability requirements for regulated markets.
