UCM1H112MNJ1MS

The UCM1H112MNJ1MS is a chip-type aluminum electrolytic capacitor designed for surface-mount assembly and high-performance power applications. It delivers 1100 µF capacitance at a 50 V rating in a compact φ18 × 16.5 mm can and is supplied in embossed carrier tape for automated placement.

Engineered for demanding environments, this low-impedance part supports operation from -55 °C to +105 °C, carries AEC-Q200 qualification, and is RoHS compliant, making it suitable for automotive electronic modules and other robust designs that require high ripple handling and long-term reliability.

Key Features

• Electrical performance — 1100 µF rated capacitance at 50 V with a tolerance of ±20% (120 Hz, 20 °C); leakage current specified at 550 µA.
• Low impedance and loss — Maximum impedance of 0.078 Ω (20 °C, 100 kHz) and tan δ of 0.10, supporting stable decoupling and filtering at higher frequencies.
• High ripple capability — Rated ripple current up to 1.98 A (105 °C, 100 kHz) and 990 mA at 120 Hz, enabling sustained AC stress handling on power rails.
• Thermal and lifetime characteristics — Operating temperature range of -55 °C to +105 °C with endurance rated to 5000 hours at 105 °C.
• Surface-mount packaging — Radial can in an SMD form-factor (φ18 × 16.5L) with embossed carrier taping for pick-and-place compatibility.
• Automotive qualification and compliance — AEC-Q200 qualified and RoHS compliant for regulated applications.

Typical Applications

• Automotive electronic control units (ECUs) — Bulk capacitance and high ripple capability support power stabilization and filtering in control modules operating across -55 °C to +105 °C.
• Power supply filtering for DC–DC converters — 50 V rating combined with low impedance and high ripple current makes this capacitor suitable for input/output smoothing in power conversion stages.
• Infotainment and telematics power rails — Compact SMD can and embossed carrier tape enable automated assembly for on-board entertainment and connectivity systems requiring reliable decoupling.

Unique Advantages

• Low impedance for improved stability: The 0.078 Ω maximum impedance at 100 kHz supports better high-frequency decoupling and reduces voltage ripple on power rails.
• High ripple endurance: Rated ripple current up to 1.98 A at 100 kHz (105 °C) permits sustained AC stress, extending service life in switching-power environments.
• Wide operating temperature and long endurance: -55 °C to +105 °C range with 5000 hours endurance at 105 °C targets long-term reliability in harsh conditions.
• Automotive-ready qualification: AEC-Q200 qualification and RoHS compliance provide design assurance for regulated automotive electronics.
• Pick-and-place friendly packaging: Embossed carrier taping and SMD can format simplify automated production and reduce assembly overhead.
