UCB1V3R3MCL1GS

The UCB1V3R3MCL1GS is a Nichicon UCB-series aluminum electrolytic chip capacitor designed for surface-mount assembly. As a chip-type, polar capacitor it delivers 3.3 µF capacitance at a 35 V rating with a compact 7 × 4 mm package footprint optimized for automated placement.

Engineered for demanding environments, this device offers a long load life of 7000 hours at +105°C, AEC-Q200 qualification, and RoHS compliance—making it suitable for automotive electronics where high-temperature endurance and reliable power decoupling are required.

Key Features

• Capacitance & Voltage — 3.3 µF capacitance with a rated voltage of 35 V and ±20% tolerance for predictable decoupling and bulk energy storage.
• High-Temperature Endurance — Rated for 7000 hours at +105°C; after endurance testing capacitance remains within ±30% of initial value, and leakage current remains at or below the initial specified value.
• AEC-Q200 Qualification — AEC-Q200 rated for automotive-grade reliability.
• Surface-Mount Chip Package — Radial, can-type SMD chip in a compact L:7 × D:4 mm package with recommended land size of 4.3 × 4.3 mm; carrier-tape compatible for automated mounting.
• Electrical Performance — Low-frequency ripple current of 14 mA at 120 Hz and high-frequency ripple current of 21 mA at 10 kHz; leakage current limited to 0.03 CV or 4 µA (whichever is greater) after two minutes at 20°C.
• Wide Operating Range — Specified for operation from −25°C to +105°C, suitable for temperature-challenging applications.
• Regulatory Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Filtering and decoupling on vehicle power rails and electronic control modules where AEC-Q200 qualification and +105°C endurance are required.
• ECU and Control Modules — Bulk support and transient suppression on power inputs for engine, transmission, and body control units operating in high-temperature environments.
• Sensor and Interface Power Conditioning — Stabilizing supply rails for sensors and signal-conditioning electronics, leveraging compact SMD packaging and automated assembly compatibility.

Unique Advantages

• Long Life at Elevated Temperature — 7000-hour load life at +105°C provides predictable aging characteristics for long-term reliability.
• Automotive-Grade Qualification — AEC-Q200 rating supports deployment in automotive systems that require validated component reliability.
• Compact, Assembly-Friendly Package — Small 7 × 4 mm chip can with carrier-tape compatibility reduces board space and supports high-throughput surface-mount processes.
• Measured Ripple Performance — Specified ripple current values at 120 Hz and 10 kHz help engineers assess suitability for power-supply filtering and decoupling tasks.
• Low Leakage Current — Leakage current specified at 0.03 CV or 4 µA (whichever is greater) supports low-standby and precision applications.
• Standards Compliance — RoHS conformity aligns with environmental and regulatory requirements.
