UCJ1V221MCL1GS

The UCJ1V221MCL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UCJ series, engineered for high-temperature operation and automated surface-mount assembly. It combines a 220 µF capacitance at 35 V with a compact SMD radial-can package suitable for space-constrained, high-reliability designs.

Designed for applications that require sustained performance at elevated temperatures, this capacitor offers AEC-Q200 qualification, low-temperature ESR specification after −40°C testing, and explicit ripple-current ratings for both low and high frequency use.

Key Features

• Capacitance & Voltage — 220 µF rated at 35 V with ±20% tolerance, providing bulk capacitance for decoupling and filtering on power rails.
• High-Temperature Operation — Specified operating temperature range from −40°C to +125°C and endurance rated for 2000 hours at 125°C.
• AEC-Q200 Qualified — Meets AEC-Q200 reliability requirements for designs that require automotive-grade qualification.
• Low-Temperature ESR Specification — ESR performance is specified after the −40°C test, supporting designs that must operate across wide temperature extremes.
• Ripple Current Ratings — 200 mA at 120 Hz and 400 mA at 10 kHz, enabling defined performance under AC ripple conditions.
• Leakage Current — After one minute at rated voltage and 20°C, leakage current is not more than 0.03CV or 4 µA, whichever is greater.
• Chip SMD Package — Radial can (SMD) chip type designed for carrier-tape feeding and automatic placement; compact footprint with body size L: 1 × D: 1 cm and recommended land pattern 1.03 × 1.03 cm.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and −40°C to +125°C rating make this capacitor suitable for in-vehicle power filtering and decoupling in electronic control units and auxiliary systems.
• Power Supply Filtering — 220 µF capacitance and specified ripple-current capability support bulk filtering and smoothing on DC‑DC converters and power rails.
• High-Temperature Industrial Controls — Endurance of 2000 hours at 125°C suits control electronics and industrial assemblies that operate near elevated ambient temperatures.

Unique Advantages

• Automotive-grade reliability: AEC-Q200 qualification plus specified endurance at 125°C provide traceable reliability for automotive and similarly demanding applications.
• Wide temperature stability: Specified performance from −40°C to +125°C and low-temperature ESR characterization ensure predictable behavior across extremes.
• Defined ripple handling: Separate ripple-current ratings at 120 Hz and 10 kHz let designers assess AC stress for both low- and high-frequency power systems.
• Automated assembly ready: Chip SMD radial-can package is carrier-tape compatible for high-volume pick-and-place manufacturing.
• Compact footprint: 1 × 1 cm body with a recommended land size helps save board space while providing substantial capacitance.
• Low leakage baseline: Clear leakage current limit (0.03CV or 4 µA after 1 minute at 20°C) supports designs sensitive to standby and bias currents.
