UCJ1E221MCL1GS

The UCJ1E221MCL1GS is a chip‑type aluminum electrolytic capacitor from Nichicon's UCJ series designed for high‑temperature operation up to +125°C. It delivers 220 µF at 25 V in a compact surface‑mount can package suitable for automated carrier‑tape placement.

Built for demanding environments, this part combines AEC‑Q200 qualification, a specified low‑temperature ESR after a −40°C test, and extended endurance ratings to support reliable decoupling and bulk energy storage in high‑temperature system designs.

Key Features

• High Temperature Range: Rated for operation from −40°C to +125°C, enabling use in elevated‑temperature environments.
• AEC‑Q200 Qualified: Series qualification provides traceable reliability criteria for applications requiring automotive‑grade screening.
• Capacitance and Voltage: 220 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low‑Temperature ESR Specification: ESR performance is specified after the −40°C test, supporting stable operation across wide temperature swings.
• Endurance and Reliability: Designed to meet endurance requirements with rated voltage applied for 2000 hours at 125°C; capacitance change remains within ±30% and leakage current meets initial specified limits after endurance testing.
• Leakage Current Specified: Leakage current after 1 minute at 20°C is not more than 0.03CV or 4 µA (whichever is greater), supporting low‑leakage applications.
• Ripple Current Ratings: 200 mA at 120 Hz and 400 mA at 10 kHz, suitable for common low‑ and high‑frequency ripple filtering duties.
• Surface Mount, Tape‑Fed Packaging: Chip‑type can package designed for automatic mounting from carrier tape; compact footprint (approx. 10 × 10 mm) and recommended land size 10.3 × 10.3 mm.
• RoHS Compliant: Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive power systems: Bulk decoupling and energy storage in control modules and power rails where AEC‑Q200 qualification and high‑temperature endurance are required.
• Power supply filtering for industrial electronics: Smoothing and ripple suppression on 25 V rails in elevated‑temperature industrial control equipment.
• Sensor and ECU circuits: Local decoupling and stabilization in electronic control units and sensor front‑ends operating across −40°C to +125°C.
• High‑temperature embedded systems: Energy storage and transient suppression where compact surface‑mount packaging and automated assembly are desired.

Unique Advantages

• High‑temperature reliability: Rated to +125°C with a 2000‑hour endurance specification to support long‑term operation in hot environments.
• Automotive‑grade qualification: AEC‑Q200 status provides documented reliability criteria for designs targeting automotive and similarly demanding applications.
• Low‑temperature performance assurance: ESR specified after −40°C testing, helping maintain performance across wide ambient ranges.
• Compact, automated assembly ready: Chip can package and carrier‑tape compatibility simplify pick‑and‑place integration and high‑volume production.
• Measured ripple handling: Defined ripple currents at both 120 Hz and 10 kHz enable confident sizing for low‑ and high‑frequency filtering tasks.
• Low leakage baseline: Clear leakage current limits (0.03CV or 4 µA) support low‑leakage DC applications and predictable margining.
