UWH1C221MCL1GS

The UWH1C221MCL1GS from Nichicon is a chip-type, high-reliability aluminum electrolytic capacitor in the UWH series designed for demanding thermal and assembly environments. It delivers 220 µF at 16 V in a compact SMD can-style package, optimized for surface-mount automated production and long-term operation at elevated temperatures.

Targeted toward applications that require proven endurance at high ambient temperatures and compatibility with high-temperature reflow processes, this capacitor combines AEC-Q200 qualification, RoHS compliance, and a rated operating range of –40°C to +125°C to support robust system designs.

Key Features

• Electrical Performance — 220 µF nominal capacitance at 16 V with ±20% tolerance; polarized aluminum electrolytic construction for bulk smoothing and energy storage.
• High-Temperature Operation — Specified for continuous use up to +125°C and guaranteed for 1000 hours at 125°C per the endurance specification.
• Reflow Compatibility — Designed to withstand peak reflow soldering at 260°C (recommended: 260°C peak for 5 s; 230°C over 60 s twice, with specific cycle guidance for larger sizes).
• Automated Assembly Ready — Chip type packaged for surface-mount placement and applicable to automatic mounting machines fed with carrier tape.
• Reliability and Qualification — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), with soldering-heat resistance and defined leakage and tan δ limits from the datasheet.
• Compact SMD Can — 1.0 cm × 1.0 cm footprint (L × D) with Surface Mount land size 1.03 cm × 1.03 cm; radial, can-style SMD package for compact board layouts.
• Measured Ripple Capability — Specified ripple current: 102 mA at 120 Hz and 153 mA at 10 kHz, documented for design margining.

Typical Applications

• Automotive electronic modules — Suitable for electronic control modules and other automotive systems where AEC-Q200 qualification and operation up to +125°C are required.
• Power management and smoothing — Bulk decoupling and energy storage in compact power circuits that operate in elevated-temperature environments.
• Automated SMD production — Designed for boards assembled with carrier-tape-fed pick-and-place equipment and reflow processes that reach 260°C peak.
• High-reliability industrial electronics — Systems needing documented endurance (1000 h at 125°C) and defined leakage and impedance behavior over temperature.

Unique Advantages

• Documented high-temperature endurance: Endurance specified for 1000 hours at 125°C with limits on capacitance change, tan δ, and leakage current to support long-term performance planning.
• 260°C reflow compatibility: Rated for 260°C peak reflow processes (recommended profile provided), enabling use with high-temperature assembly flows.
• AEC-Q200 qualification: Provides a recognized qualification level for demanding vehicle and similar applications where component-level reliability matters.
• Compact, machine-friendly package: 1 × 1 cm SMD can in carrier-tape compatible format simplifies BOM and supports automated placement.
• Measured ripple specifications: Published ripple current values at 120 Hz and 10 kHz allow designers to evaluate thermal and filtering performance against system requirements.
• Regulatory compliance: RoHS compliant under 2011/65/EU and (EU)2015/863 for environmental conformity in regulated markets.
