PCM1E221MCL1GS

The PCM1E221MCL1GS is a conductive-polymer aluminum solid electrolytic chip capacitor in an SMD can package, offering 220 µF capacitance at 25 V. It is built for high-reliability power smoothing and decoupling in demanding temperature environments.

Designed for automotive and other high-temperature electronics, this part combines low ESR and high ripple-current capability with long-life endurance to support robust power delivery in compact surface-mount assemblies.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of ±20%.
• Conductive Polymer Construction — Solid conductive polymer electrolyte provides stable electrical performance and low ESR.
• Low ESR — 24 mΩ equivalent series resistance measured at 100 kHz, enabling efficient high-frequency decoupling.
• High Ripple Current — Rated ripple current up to 2 A at 100 kHz (1 A at 120 Hz) for applications with significant AC content on DC rails.
• High-Temperature Endurance — Long life specification of 8000 hours at 125°C, with ESR and capacitance retention defined after endurance.
• Automotive-Grade Qualification — AEC-Q200 qualified for automotive electronic use.
• Wide Operating Temperature — Specified for −55°C to +125°C operation to support harsh-environment electronics.
• SMD Package & Reflow Compatible — Surface-mount can package; compatible with lead-free reflow soldering up to a 260°C peak.
• Mounting & Footprint — Surface mount (can-style SMD) with recommended land size 10.3 mm × 10.3 mm and part dimensions L: 0.8 cm × D: 1.0 cm.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Power Electronics — Bulk decoupling and smoothing in control modules and ECUs where AEC-Q200 qualification and high-temperature endurance are required.
• Power Supply Filtering — Input/output filtering and hold-up for DC–DC converters and power rails subjected to high ripple current and elevated temperatures.
• Industrial High-Temperature Electronics — Power conditioning in industrial modules and assemblies that operate across −55°C to +125°C.

Unique Advantages

• Long high-temperature lifespan: 8000 hours at 125°C provides predictable end-of-life characteristics for designs targeting extended service in hot environments.
• Low ESR for improved efficiency: 24 mΩ at 100 kHz reduces power loss and thermal stress in high-frequency power applications.
• High ripple handling: 2 A ripple current at 100 kHz supports higher AC loading on DC rails without compromising performance.
• Automotive qualification: AEC-Q200 status supports use in automotive-grade assemblies requiring recognized reliability standards.
• Reflow-capable SMD form factor: Lead-free reflow compatibility to 260°C simplifies integration into modern surface-mount production flows.
• RoHS compliance: Meets current RoHS directive requirements for environmentally regulated designs.
