UUJ2W3R3MNQ1MS

The UUJ2W3R3MNQ1MS is a chip-type aluminum electrolytic capacitor designed for surface mounting on high-density printed circuit boards. It provides a 3.3 µF capacitance at a 450 V rating in a compact radial can SMD package, and is polarized for DC applications.

Engineered for demanding environments, this part is RoHS compliant and AEC-Q200 qualified. Key reliability attributes include an operating temperature range of -40 °C to 105 °C and a rated endurance of 5000 hours at 105 °C.

Key Features

• Electrical Performance — 3.3 µF capacitance with a rated voltage of 450 V and tolerance of ±20%, suitable for higher-voltage DC applications where compact surface-mount capacitors are required.
• Ripple Current Ratings — Specified ripple current of 40 mA at 120 Hz and 64 mA at 10 kHz to inform thermal and filtering design considerations.
• Package & Mounting — Chip-type radial can SMD package sized L: 1.35 × D: 1.25 cm with recommended surface-mount land size L: 1.28 × W: 1.28 cm; compatible with automatic mounting machines fed by carrier tape.
• Reliability & Lifetime — AEC-Q200 qualified with a rated life of 5000 hours at 105 °C, providing documented endurance for elevated-temperature deployments.
• Temperature Range — Rated for operation from -40 °C to 105 °C, matching common requirements for temperature-variable environments.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU,(EU)2015/863).
• Polarized Design — Single-polarity construction suitable for DC decoupling and energy storage where polarity is managed in the circuit.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and a -40 °C to 105 °C operating range make this capacitor appropriate for automotive electronic modules that require surface-mount, high-voltage capacitors.
• High-Density PCB Assemblies — Chip-type SMD packaging is optimized for densely populated boards where board space and automatic placement are priorities.
• Automated SMT Production — Designed for use with automatic mounting machines fed by carrier tape, supporting high-volume assembly workflows.
