UCM1H471MNJ1MS

The UCM1H471MNJ1MS is a chip-type, low-impedance aluminum electrolytic capacitor in a compact surface-mount can package designed for high-capacitance decoupling and bulk storage in constrained board space. It delivers 470 µF at 50 V with AEC-Q200 qualification and RoHS compliance, making it suitable for demanding electronic power applications, including automotive systems.

Optimized for elevated-temperature operation and high ripple conditions, this device combines a 5000-hour endurance at 105°C with frequency-dependent ripple capability to support power-supply smoothing and decoupling across a broad operating range.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance rated at 50 V with tolerance -20% to +20% for predictable energy storage in power circuits.
• Low-loss Performance — Tangent of loss angle (tan δ) of 0.10 measured at 20°C, 120 Hz (rating-specific), supporting lower dissipation in AC and ripple environments.
• Ripple Current Handling — Rated low-frequency ripple current of 670 mA at 120 Hz and high-frequency ripple current of 1.34 A at 10 kHz to support both mains-frequency and switching-regulator applications.
• Leakage Current — Specified leakage current of 235 µA for predictable standby and quiescent current behavior after voltage application.
• High-Temperature Endurance — 5000 hours life at 105°C with defined limits: capacitance change within ±30% and tan δ up to 200% of initial specified value, enabling reliable operation in elevated-temperature environments.
• Wide Temperature Range — Operates from -55°C to +105°C; impedance stability is specified across low temperatures (Z(-25°C)/Z(+20°C) ≤ 2, Z(-45°C)/Z(+20°C) ≤ 3 for rated voltages).
• Compact SMD Package — Radial can SMD chip in φ12.5 × 13.5 mm (D × L) package with surface-mount land size 12.8 × 12.8 mm, supplied in embossed carrier taping for automated placement.
• Quality & Compliance — AEC-Q200 rated and RoHS compliant, suitable for regulated manufacturing and automotive-grade design flows.

Typical Applications

• Automotive Power Rails — Bulk decoupling and smoothing for vehicle electronic power supplies, where AEC-Q200 qualification and elevated-temperature endurance are required.
• DC–DC Converters — Output filtering and energy buffering for switching regulators, leveraging the part’s high-frequency ripple current capability.
• Industrial Power Supplies — Energy storage and transient suppression in compact SMD designs operating across -55°C to +105°C.
• Embedded Systems — Board-level bulk capacitance for microcontroller and system power stability in constrained form factors.

Unique Advantages

• High energy density in a small SMD can: 470 µF at 50 V in a φ12.5 × 13.5 mm package delivers substantial bulk capacitance where board space is limited.
• Designed for high-ripple environments: Specified ripple currents at 120 Hz and 10 kHz provide measurable margins for both low- and high-frequency switching applications.
• Long elevated-temperature life: 5000 hours at 105°C with defined post-test electrical limits supports designs targeted for long-term reliability.
• Automotive-grade qualification: AEC-Q200 rating and RoHS compliance simplify qualification for vehicle electronics and regulated product lines.
• Reliable low-temperature behavior: Specified impedance ratios at -25°C and -45°C ensure performance across cold-start and low-temperature conditions.
• Production-ready packaging: Embossed carrier taping enables automated assembly and efficient high-volume manufacturing.
