UWT1H3R3MCL1GB

The UWT1H3R3MCL1GB is a Nichicon UWT series aluminum electrolytic chip capacitor in a compact surface-mount can package. It provides 3.3 µF capacitance at a 50 V rating and is designed for automated SMT assembly on high-density printed circuit boards.

Engineered for demanding temperature environments, this chip-type capacitor operates from −55 °C to +105 °C, carries AEC-Q200 qualification, and is RoHS compliant — making it suitable for automotive electronic applications that require wide temperature tolerance and reliability.

Key Features

• Capacitance & Voltage — 3.3 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance (120 Hz, 20 °C).
• Wide Temperature Range — Rated for operation from −55 °C to +105 °C to support applications with broad thermal requirements.
• AEC-Q200 Qualified — Series-level qualification noted in the product data for automotive-grade reliability.
• Endurance — Rated for 1000 hours at 105 °C with specified limits on capacitance change (within ±20% for 25 V and above) and leakage current remaining at or below initial specified values after the test.
• Low Ripple Current — Specified ripple current of 14 mA at 120 Hz and 21 mA at 10 kHz for decoupling and filtering stability at low amplitudes and higher frequencies.
• Chip SMD Can Package — Compact dimensions L: 5.4 × D: 4.0 mm with surface-mount land footprint of 4.3 × 4.3 mm; designed for high-density PCB mounting and carrier-tape automated placement.
• Leakage Current Specification — Series-level leakage current limit after 2 minutes at 20 °C: not more than 0.01CV or 3 µA, whichever is greater.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronic modules — SMD chip capacitor suitable for use in modules where AEC-Q200 qualification and −55 °C to +105 °C operation are required.
• Automotive power rails — 3.3 µF at 50 V with specified ripple current values makes the part suitable for local decoupling and smoothing on automotive power lines.
• Automated high-density PCB assembly — Designed for carrier-tape feeding and surface mounting on compact boards for space-constrained automotive electronics.

Unique Advantages

• Wide operating temperature capability: Supports −55 °C to +105 °C for designs exposed to automotive temperature extremes.
• AEC-Q200 qualification: Series-level automotive qualification supports integration into automotive-grade systems where component-level qualification is required.
• Compact SMD can footprint: Small L: 5.4 × D: 4.0 mm size and 4.3 × 4.3 mm land pattern help reduce PCB area while enabling automatic placement.
• Proven endurance at elevated temperature: 1000 hours at 105 °C with controlled limits on capacitance change and leakage current for predictable long-term behavior.
• Low leakage and specified ripple behavior: Leakage current limit and ripple current specifications provide predictable performance for low-amplitude filtering and decoupling tasks.
• RoHS compliance and automated assembly compatibility: Meets RoHS requirements and is designed for carrier-tape automated mounting to simplify supply-chain and production processes.
