UWG1A221MNL1GS

The UWG1A221MNL1GS is a chip-type, low-impedance aluminum electrolytic capacitor from Nichicon's UWG series, optimized for surface-mount use on high-density PC boards. It delivers 220 µF capacitance at a 10 V rating with a wide operating temperature range of −55°C to +105°C, and is designed for automated, tape-fed assembly.

Targeted at applications requiring robust temperature endurance and reliable SMD mounting, this AEC‑Q200 qualified, RoHS-compliant capacitor offers long-term performance characteristics with a rated lifetime of 1000 hours at 105°C.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance at a 10 V rated voltage, with capacitance tolerance of ±20%.
• Low Impedance Performance — Low impedance design with a specified impedance of 300 mΩ to support stable decoupling and filtering in power circuits.
• Ripple Current Capability — Rated ripple current of 225 mA at 120 Hz and 450 mA at 10 kHz, enabling effective handling of both low- and high-frequency ripple components.
• Wide Temperature Range — Operates from −55°C to +105°C to suit demanding thermal environments.
• Reliability & Endurance — AEC‑Q200 qualified and specified for 1000 hours of endurance at 105°C; capacitance change after the endurance test stays within ±20% and leakage current remains within initial limits.
• Surface-Mount Chip Package — Chip-type SMD (radial can) package designed for high-density PCBs and compatibility with automatic carrier-tape mounting.
• Leakage Current Specification — After 2 minutes at rated voltage and 20°C, leakage current is ≤ 0.01CV or 3 µA, whichever is greater.
• Low-Temperature Stability — Impedance stability characterized down to −55°C (Z(−55°C)/Z(+20°C) ≤ 4 for the 10 V rating, measured at 120 Hz).
• RoHS Compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics — Suitable for automotive electronic modules where AEC‑Q200 qualification and wide temperature operation are required.
• High-density surface-mount PCBs — Chip-type package is designed for compact board layouts that demand reliable SMD capacitors.
• Automated, high-volume assembly — Compatible with carrier-tape feeding for automatic mounting machines, streamlining manufacturing throughput.
• High-temperature endurance systems — Specified 1000-hour life at 105°C for designs exposed to sustained elevated temperatures.

Unique Advantages

• Qualified for automotive environments: AEC‑Q200 qualification provides an explicit benchmark for reliability in automotive-grade designs.
• Wide operating temperature range: −55°C to +105°C rating supports designs across harsh thermal conditions without compromising capacitance specifications.
• Low-impedance construction: 300 mΩ impedance and defined tan δ (max. 0.19 at 10 V, 120 Hz, 20°C) help maintain stable power delivery and filtering performance.
• Dual-frequency ripple handling: Specified ripple currents at 120 Hz and 10 kHz enable predictable behavior for both mains-derived and switching-regulator ripple.
• Assembly-friendly package: Chip-type SMD format and carrier-tape compatibility reduce assembly complexity and support automated production lines.
• Endurance-proven: 1000 hours at 105°C with controlled capacitance and leakage results offers design confidence for long-term deployments.
