UCM2A391MNJ1MS

The UCM2A391MNJ1MS is a chip-type, low-impedance aluminum electrolytic capacitor in a surface-mount radial can package. It provides 390 µF capacitance at a 100 V rating, designed for assembly on automated carrier-tape lines and for use in applications requiring elevated temperature endurance.

Key value propositions include high ripple-current capability, long-term endurance at elevated temperature, AEC-Q200 qualification, and RoHS compliance—making it suitable for demanding electronic and automotive power applications.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 100 V operation.
• Low Loss / Low Impedance — Tangent of loss angle (tan δ) specified at 0.07 (measured at 20°C, 120 Hz), supporting efficient charge/discharge behavior.
• High Ripple Current — Low-frequency ripple current of 1.02 A at 120 Hz and high-frequency ripple current of 2.04 A at 10 kHz for reduced heating under AC stress.
• Leakage Current — Specified leakage current of 390 µA after rated voltage application, for predictable standby characteristics.
• Reliability & Endurance — Rated for 5000 hours at 105°C (endurance), with endurance and shelf-life characteristics defined by the series specifications.
• Temperature Range — Operates from −55°C to +105°C to accommodate a broad set of thermal environments.
• Package & Mounting — Surface-mount radial can (chip type) with size φ16 × 21.5L (D × L); supplied in embossed carrier taping compatible with automatic mounting machines. Recommended surface-mount land size: 1.63 × 1.63 cm.
• Compliance & Qualification — AEC-Q200 qualified and RoHS compliant as specified in the product data.

Typical Applications

• Automotive systems — Designed for use in AEC-Q200 environments where 100 V ratings, high ripple handling, and extended high-temperature endurance are required.
• Surface-mount power modules — Suited to automated SMT assembly thanks to embossed carrier taping and chip-type packaging.
• High-voltage DC bus and power filtering — 100 V rating and high ripple-current capability support decoupling and smoothing in power electronics.

Unique Advantages

• High-voltage capability: 100 V rating enables use in higher-voltage power rails and DC-link applications without stacking.
• Strong ripple performance: Specified LF and HF ripple currents (1.02 A at 120 Hz; 2.04 A at 10 kHz) reduce operating temperature rise under AC loading.
• Long high-temperature life: 5000 hours at 105°C provides measurable endurance for designs exposed to sustained elevated temperatures.
• Automotive-grade qualification: AEC-Q200 recognition supports deployment in automotive electronics that require industry-standard validation.
• SMD-ready packaging: Embossed carrier taping and chip-type format streamline automated placement and throughput.
• Predictable electrical behavior: Low tan δ (0.07 at 20°C, 120 Hz) and defined leakage current support reliable filter and energy-storage performance.
