UCZ1J181MNQ1MS

The UCZ1J181MNQ1MS is a chip-type, surface-mount aluminum electrolytic capacitor designed for high-reliability applications up to +125°C. It delivers 180 µF of capacitance at a 63 V rating in a compact φ12.5 × 13.5 mm can package suitable for automated assembly.

Engineered for power filtering and decoupling in thermally demanding environments, the device combines low ESR performance, measurable high-frequency ripple handling, and AEC-Q200 qualification for use in demanding electronic systems.

Key Features

• Capacitance & Voltage: 180 µF rated capacitance with a 63 V voltage rating and ±20% tolerance, providing bulk energy storage for power rails and decoupling.
• Temperature Range & Endurance: Operates from −40°C to +125°C with a rated endurance of 3000 hours at 125°C, supporting long-term operation in high-temperature environments.
• Low Temperature ESR Specification: ESR specified at −40°C and 20°C with an ESR of 200 mΩ measured at 20°C/100 kHz, supporting low-impedance performance across frequencies.
• Ripple Current Capability: Handles 500 mA at 120 Hz (low frequency) and 1.0 A at 10 kHz (high frequency), enabling effective smoothing of both low- and high-frequency ripple.
• Leakage & Loss Angle: Leakage current specified at 113.4 µA and tan δ (loss tangent) of 0.12 measured at 20°C, 120 Hz, allowing predictable loss and leakage behavior for precision designs.
• Package & Assembly: Surface-mount, radial can (SMD) package φ12.5 × 13.5 mm compatible with embossed carrier taping for automatic placement; recommended land size L:1.28 × W:1.28 cm.
• Standards & Compliance: AEC-Q200 qualified and RoHS compliant, aligning with reliability and environmental requirements for regulated applications.

Typical Applications

• Automotive Electronics — Bulk filtering and decoupling in control modules and power supplies where operation to +125°C and AEC-Q200 qualification are required.
• Power Supply Filtering — Energy storage and ripple suppression for DC–DC converters and regulator outputs, benefitting from the capacitor's high-frequency ripple capability and low ESR.
• Industrial Controls — Decoupling and smoothing in motor drives and power control circuits that operate in elevated ambient temperatures.

Unique Advantages

• High-temperature endurance: Rated for 3000 hours at 125°C, enabling reliable operation in thermally stressed designs.
• Measured low-temperature ESR: ESR specification at −40°C and 20°C provides predictable performance across wide temperature swings, useful for designs exposed to cold-start and hot-operating conditions.
• Dual-frequency ripple handling: Specified ripple currents at 120 Hz and 10 kHz allow the part to address both mains-frequency and switching-frequency ripple with defined limits.
• AEC-Q200 qualification and RoHS compliance: Supports deployment in regulated and reliability-focused programs while meeting environmental directives.
• Automated assembly ready: Embossed carrier taping and an SMD radial can package enable integration into high-volume SMT production flows.
