UWH1C101MCL1GS

The UWH1C101MCL1GS is a chip‑type aluminum electrolytic capacitor designed for high‑reliability, high‑temperature surface‑mount applications. It is AEC‑Q200 qualified and rated for operation from −40°C to +125°C, providing robust electrical performance for demanding assemblies.

Engineered for automatic mounting and lead‑free reflow processing, this 100 µF, 16 V polarized capacitor combines elevated temperature endurance with controlled impedance and leakage characteristics useful in automotive and other high‑temperature electronic systems.

Key Features

• Capacitance & Voltage — 100 µF rated capacitance at 16 V for bulk decoupling and energy storage in compact SMD form.
• Temperature Range & Endurance — Rated for −40°C to +125°C operation with endurance specified as 1000 hours at 125°C under rated voltage; capacitance change within ±30% after endurance test.
• High‑Temperature Reflow Compatibility — Designed to withstand 260°C peak reflow soldering (recommended: 260°C peak 5 s; 230°C over 60 s ×2 for standard sizes), and meets soldering heat resistance (250°C hot‑plate, 30 s) with capacitance change within ±10%.
• Electrical Performance — Low leakage current (≤0.03CV or 4 µA after 1 minute at 20°C) and specified tan δ (max. 0.24 at 16 V, 120 Hz, 20°C) for predictable AC behavior.
• Ripple Current Ratings — Rated ripple currents: 66 mA at 120 Hz and 99 mA at 10 kHz, useful for filtering and smoothing in pulsed or noisy power rails.
• Package & Mounting — Chip type, surface mount can style suitable for automated assembly; designed for carrier‑tape feed and placement. Typical size: L 1.0 × D 0.8 cm with recommended land size 8.3 × 8.3 mm.
• Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).
• Polarized — Polarized aluminum electrolytic chemistry for DC power applications.

Typical Applications

• Automotive electronic modules — AEC‑Q200 qualification and +125°C endurance make this capacitor suitable for control modules and other vehicle electronics that require high‑temperature stability.
• Power supply filtering in harsh environments — 100 µF at 16 V with defined ripple current and low leakage supports bulk smoothing and decoupling where temperature and reliability are critical.
• Automated surface‑mount assembly — Chip form factor and carrier‑tape compatibility simplify placement on high‑volume PCBs assembled with reflow processes.

Unique Advantages

• High‑temperature endurance: Specified for 1000 hours at +125°C under rated voltage, providing predictable long‑term performance in hot environments.
• Reflow process compatibility: Designed for 260°C peak reflow profiles and verified resistance to soldering heat, enabling lead‑free assembly without special handling.
• AEC‑Q200 qualified: Meets automotive component qualification standards to support designs that require recognized reliability credentials.
• Measured AC characteristics: Documented tan δ and impedance stability at low temperature (Z(−40°C)/Z(+20°C) = 8 for 16 V) help designers predict frequency and temperature behavior.
• Compact SMD can package: Chip type construction with defined land pattern (8.3 × 8.3 mm) reduces PCB footprint while remaining compatible with automated placement.
