UWT0G101MCL1GB

The UWT0G101MCL1GB is a chip-type aluminum electrolytic capacitor designed for surface mounting on high-density PC boards. It delivers 100 µF capacitance at a 4 V rating, with a wide operating temperature range of −55 °C to +105 °C and AEC-Q200 qualification for demanding environments.

Built for automated production, this part is carrier-tape compatible and RoHS compliant, making it suitable for automotive and other reliability-focused electronic systems that require compact power decoupling and energy storage in confined SMD footprints.

Key Features

• Capacitance & Voltage — 100 µF rated at 4 V for bulk decoupling and local energy storage on low-voltage power rails.
• Wide Temperature Range — Guaranteed operation from −55 °C to +105 °C to support designs exposed to extreme ambient conditions.
• Package & Mounting — Chip-type radial can designed for surface-mounting on high-density PCBs; compatible with automatic mounting machines fed by carrier tape.
• Size and Land Pattern — Compact dimensions L: 5.4 × D: 6.3 mm with recommended SMD land size L: 6.6 × W: 6.6 mm for PCB layout planning.
• Tolerance & Polarity — Polarized device with capacitance tolerance of ±20% (at 120 Hz, 20 °C).
• Reliability & Endurance — AEC-Q200 qualified; rated endurance of 1000 hours at 105 °C with capacitance change within ±25% for voltage ratings ≤16 V.
• Leakage Current — Per datasheet formula (I ≤ 0.01CV or 3 µA), the specified leakage after 2 minutes at 20 °C is not more than 4 µA for this 100 µF, 4 V unit.
• Ripple Current — 60 mA at 120 Hz and 90 mA at 10 kHz, useful for assessing AC stress in power-supply filtering.
• Low‑temperature Stability — Impedance ratios relative to +20 °C: Z(−25 °C)/Z(+20 °C) = 7 and Z(−40 °C)/Z(+20 °C) = 15 at 120 Hz, aiding low-temperature performance planning.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronic modules — Local decoupling and energy buffering for control units and sensor electronics where AEC-Q200 qualification and wide temperature range are required.
• On-board power filtering — Smoothing and ripple suppression on low-voltage power rails in compact, high-density PCBs.
• Backup and hold-up circuits — Providing short-term energy storage for microcontrollers and real-time clocks in systems with constrained board area.
• High-density consumer and industrial electronics — Surface-mount form factor supports automated assembly and tight PCB layouts for portable or space-limited devices.

Unique Advantages

• Wide operating temperature span: −55 °C to +105 °C enables consistent performance across harsh environments and thermal cycles.
• Automated-assembly ready: Carrier-tape compatibility and chip-type SMD can improve throughput and repeatability in high-volume manufacturing.
• AEC-Q200 qualification: Provides an automotive-grade reliability baseline for designs that require established component-level robustness.
• Compact footprint: Small L × D (5.4 × 6.3 mm) and defined land pattern (6.6 × 6.6 mm) help preserve PCB area while delivering 100 µF capacitance.
• Defined endurance and leakage: 1000 hours at 105 °C endurance with predictable capacitance drift limits and a leakage specification of up to 4 µA for margin calculations.
• Measurable ripple handling: Published ripple currents (60 mA @120 Hz, 90 mA @10 kHz) simplify thermal and stress budgeting in power-supply designs.
