UCM1J911MNS1MS

The UCM1J911MNS1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount applications. With a rated voltage of 63 V and a capacitance of 910 µF (±20%), it delivers high bulk capacitance in an SMD can package suited for automated assembly.

Engineered for demanding environments, this part offers a wide operating temperature range (−55 °C to +105 °C), AEC-Q200 rating, vibration resistance, and a 5000-hour endurance at 105 °C—attributes aimed at robust, long-life designs in automotive and industrial power systems.

Key Features

• Core Electrical Performance — 910 µF capacitance with ±20% tolerance and a rated voltage of 63 V; low-impedance design for improved transient and bulk energy handling.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.08 measured at 20 °C, 120 Hz, providing predictable AC loss behavior at the specified conditions.
• Ripple Current Capability — Low-frequency ripple current 1.165 A (120 Hz) and high-frequency ripple current 2.33 A (10 kHz), supporting filtering and smoothing in switching power applications.
• Leakage Current — Specified leakage current of 573.3 µA, measurable after rated-voltage application.
• Temperature and Endurance — Operating range −55 °C to +105 °C with 5000 hours endurance at 105 °C under rated voltage.
• Package and Mounting — Chip-type, surface-mount radial can (φ16 × 21.5 L / L: 2.15 × D: 1.6 cm) supplied in embossed carrier taping for automatic placement; recommended land size L: 1.63 × W: 1.63 cm.
• Qualification and Conformity — AEC-Q200 rating and RoHS compliance; vibration resistant construction for mechanically demanding assemblies.

Typical Applications

• Automotive Power Electronics — Bulk smoothing and energy storage on 63 V rails where high capacitance and AEC-Q200 qualification support reliability in vehicle environments.
• DC–DC Converter Outputs — Output filtering for converters that require high ripple-current capacity (2.33 A at 10 kHz) and stable performance across −55 °C to +105 °C.
• Engine Control and Body Electronics — Power-rail decoupling and transient suppression in systems needing long-term endurance (5000 h at 105 °C) and vibration resistance.

Unique Advantages

• High Bulk Capacitance in SMD Can — 910 µF packaged in a φ16 × 21.5 mm SMD can reduces board area compared with equivalent through-hole designs while enabling automated placement.
• Built for Harsh Temperatures — Rated for −55 °C to +105 °C with a 5000-hour life at 105 °C, supporting designs that require long-term high-temperature endurance.
• Robust Ripple Handling — Specified ripple currents at both low and high frequencies (1.165 A at 120 Hz, 2.33 A at 10 kHz) enable reliable filtering across switching and line-frequency regimes.
• AEC-Q200 Qualification — Component-level qualification for demanding applications where industry-level reliability verification is required.
• Assembly-Ready Packaging — Embossed carrier taping and SMD form factor facilitate high-volume automated assembly and consistent placement.
• Low Loss Behavior — Tan δ of 0.08 (20 °C, 120 Hz) supports predictable AC loss performance in specified measurement conditions.
