UCZ1J151MNQ1MS

The UCZ1J151MNQ1MS is a chip-type aluminum electrolytic capacitor designed for high-temperature, high-reliability applications. It is a polarized surface-mount radial can (SMD) capacitor specified for operation from -40°C to +125°C and is AEC-Q200 qualified.

Engineered for power decoupling and smoothing in harsh thermal environments, this 150 µF, 63 V capacitor delivers controlled ESR and defined ripple handling for designs that require predictable behavior at low temperature and under long-term high-temperature stress.

Key Features

• Electrical Performance — 150 µF capacitance with ±20% tolerance and a 63 V rated voltage; polarized design for power filtering and energy storage.
• Low-temperature ESR Spec — ESR specified as 200 mΩ at 100 kHz and includes ESR verification after -40°C test, providing predictable impedance at low temperatures.
• Ripple Handling — Rated ripple current of 500 mA at 120 Hz and 1 A at 10 kHz for AC stress in power circuits.
• High-temperature Reliability — Operates across -40°C to +125°C and specified for 3,000 hours at 125°C, supporting long-term use in elevated temperature environments.
• Package & Mounting — Chip-type radial can SMD designed for automatic mounting with carrier tape; Surface Mount mounting type and surface-mount land size L: 1.28 × W: 1.28 cm facilitate PCB integration.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant, reflecting suitability for regulated, high-reliability applications.

Typical Applications

• Automotive power systems — Bulk filtering and decoupling in power electronics where AEC-Q200 qualification and operation to +125°C are required.
• Industrial power supplies — Energy smoothing and ripple suppression in converters and regulators operating in elevated ambient temperatures.
• DC–DC converters — Output and intermediate stage smoothing where predictable low-temperature ESR and defined ripple ratings improve stability.
• Harsh-environment electronics — Components for equipment exposed to broad temperature ranges that need long endurance at high temperature.

Unique Advantages

• Predictable low-temperature behavior: ESR specified after -40°C testing gives engineers measurable impedance performance in cold conditions.
• High-temperature endurance: 3,000 hours at 125°C provides a documented lifetime metric for thermal reliability planning.
• Compact SMD can package: Chip-type radial can in a surface-mount form factor supports automated assembly and reduces board space compared with through-hole equivalents.
• Defined ripple capability: Specified ripple currents at 120 Hz and 10 kHz help ensure reliable filtering across common switching and line-frequency conditions.
• Industry qualification and compliance: AEC-Q200 qualification plus RoHS compliance supports regulated designs and procurement requirements.
