UCJ1C221MCL1GS

The UCJ1C221MCL1GS is a chip‑type aluminum electrolytic capacitor from Nichicon’s UCJ series, specified for continuous operation up to +125°C. It provides 220 µF capacitance at a 16 V rating in a compact surface‑mount radial can package designed for automated carrier‑tape mounting.

Designed for high‑temperature, high‑reliability electronics, the part combines high capacitance density with series electrical and environmental qualifications such as AEC‑Q200 and RoHS compliance.

Key Features

• Core electricals — 220 µF capacitance at 16 V with ±20% tolerance; polarized aluminum electrolytic chemistry suited for bulk energy storage and smoothing.
• High‑temperature rating — Specified operating range −40°C to +125°C with an endurance of 2000 hours at 125°C, enabling use in elevated‑temperature environments.
• Low‑temperature performance — Added ESR specification after −40°C testing to ensure performance at cold extremes; series impedance ratio Z(−40°C)/Z(+20°C) for 16 V is 8 (per series specification).
• Loss and leakage — tan δ (loss angle) for 16 V is specified at 0.24 (120 Hz, 20°C); leakage current limited to 0.03CV or 4 µA, whichever is greater (after 1 minute at rated voltage, 20°C).
• Ripple current capability — Rated ripple handling of 200 mA at 120 Hz and 400 mA at 10 kHz to support power smoothing and decoupling tasks.
• Package & mounting — Chip type radial can SMD for surface mount assembly; compatible with automatic mounting machines fed with carrier tape. Nominal footprint/size: L: 1 × D: 1 cm; recommended land size L: 1.03 × W: 1.03 cm.
• Reliability & compliance — AEC‑Q200 qualified for high‑reliability applications and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics — Energy storage and smoothing in vehicle electronics where AEC‑Q200 qualification and +125°C operation are required.
• Power modules and DC‑DC converters — Bulk decoupling and ripple suppression in high‑temperature power assemblies.
• Industrial control electronics — Capacitor solution for control boards and modules operating in elevated ambient temperatures.

Unique Advantages

• High‑temperature endurance: 2000 hours at 125°C provides predictable lifetime performance for thermal‑stress designs.
• Automotive‑grade qualification: AEC‑Q200 status supports use in demanding, reliability‑focused systems.
• Low‑temperature ESR verification: Added ESR specification after −40°C testing improves confidence in cold‑start and low‑temperature operation.
• Compact surface‑mount form factor: Chip‑type radial can SMD footprint enables automated assembly while delivering high capacitance in a small area.
• Measured ripple capability: Defined ripple ratings at 120 Hz and 10 kHz allow designers to match the part to expected power‑line conditions.
• Regulatory compliance: RoHS conformity simplifies regulatory tracking for environmental requirements.
