UWH1A221MCL1GS

The UWH1A221MCL1GS is a chip-type aluminum electrolytic capacitor designed for high-reliability surface-mount applications. It delivers 220 µF capacitance at a 10 V rating, engineered for continuous operation up to +125°C and compatible with 260°C peak reflow processing.

Targeted at demanding electronics where elevated temperature tolerance, stable ripple performance and automated assembly are required, this part combines AEC-Q200 qualification, embossed carrier taping for pick-and-place, and a compact φ8 × 10 mm can-style SMD package.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with ±20% tolerance at 20°C, rated for 10 V operation.
• High-temperature operation — Specified operating range −40°C to +125°C and endurance of 1000 hours at 125°C.
• High-reliability construction — AEC-Q200 qualified and designed as a chip-type, high-reliability aluminum electrolytic capacitor.
• Reflow compatibility — Compatible with 260°C peak reflow soldering; recommended reflow condition notes 260°C peak for 5 s and 230°C over 60 s (refer to series guidance for part-size specifics).
• Electrical loss & leakage — tanδ (DF) up to 0.32 measured at 20°C, 120 Hz; specified leakage current value 66 µA.
• Ripple current capability — Low-frequency ripple current 90 mA at 120 Hz and high-frequency ripple current 135 mA at 10 kHz.
• Compact SMD package — φ8 × 10 mm can-style SMD (Size dimension L: 1.0 cm × D: 0.8 cm) with embossed carrier taping for automated placement; recommended surface-mount land size 8.3 × 8.3 mm.
• RoHS compliant — Meets RoHS directive requirements.

Typical Applications

• Automotive electronic modules — Smoothing and energy buffering in control modules and sensor electronics where AEC-Q200 qualification and +125°C operation are required.
• Power management — Decoupling, filtering and hold-up in DC–DC converters and power-supply rails exposed to elevated temperatures and ripple currents.
• Industrial controls — Bulk and bypass capacitance for motor drives, inverters and embedded controllers operating in high-temperature environments.
• Telematics and onboard electronics — Energy storage and transient suppression in compact, surface-mount form factors used in ruggedized electronic assemblies.

Unique Advantages

• High-temperature endurance — Rated for continuous use at up to +125°C with a 1000-hour endurance specification, supporting long-term reliability in hot environments.
• Reflow-ready for automated assembly — Designed for 260°C peak reflow and supplied in embossed carrier tape for seamless pick-and-place integration.
• Automotive-grade qualification — AEC-Q200 qualification provides documented suitability for demanding, mission-critical electronic designs.
• Compact, can-style SMD — φ8 × 10 mm footprint provides substantial capacitance in a small surface-mount package, simplifying board layout compared with larger through-hole solutions.
• Measured ripple and leakage characteristics — Specified low- and high-frequency ripple current ratings and a defined leakage current make it straightforward to design for thermal and ripple constraints.
• Regulatory compliance — RoHS compliance supports use in regions requiring hazardous-substance restrictions.
