UWH1E221MCL1GS

The UWH1E221MCL1GS is a chip-type aluminum electrolytic capacitor from Nichicon designed for high-reliability, high-temperature surface-mount applications. It delivers 220 µF capacitance at a 25 V rating in a compact 10 mm × 10 mm package (L × D: 1 cm × 1 cm) and is polarized for standard electrolytic use.

Engineered for elevated temperature operation and robust assembly conditions, this part supports sustained operation to +125°C, compatibility with 260°C peak reflow soldering, and is AEC-Q200 qualified with RoHS compliance—making it suitable for demanding automotive and high-temperature electronics environments.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 25 V for bulk decoupling and energy storage in compact SMD form.
• High-Temperature Operation — Rated for continuous use from −40°C to +125°C with an endurance specification of 1000 hours at 125°C.
• High-Temperature Reflow Compatible — Designed to withstand 260°C peak reflow soldering; recommended reflow condition: 260°C peak for 5 seconds (with 230°C over 60 seconds specified for multi-pass conditions).
• Reliability & Qualification — AEC-Q200 qualified for higher reliability applications and compliant to RoHS (2011/65/EU, (EU)2015/863).
• Low Leakage Current — After 1 minute at rated voltage (20°C), leakage current ≤ 0.03CV or 4 µA, whichever is greater.
• Performance at Frequency & Temperature — Ripple current ratings of 116 mA at 120 Hz and 174 mA at 10 kHz; impedance and tan δ characteristics specified for reliable performance down to −40°C.
• Surface-Mount, Tape-Fed Package — Chip-type can package suitable for automated placement; applicable to automatic mounting machines fed with carrier tape.

Typical Applications

• Automotive Electronics — Power decoupling and energy storage in automotive control modules where AEC-Q200 qualification and +125°C endurance are required.
• High-Temperature Power Electronics — Filtering and bulk capacitance in assemblies that must tolerate elevated board and reflow temperatures.
• Industrial Controls — Reliable smoothing and transient buffering in industrial controllers and modules operated in warm environments.

Unique Advantages
