UBX1H471MHL

The UBX1H471MHL is a radial-lead aluminum electrolytic capacitor in Nichicon’s UBX laminated-case series, specified for high-temperature operation up to +150°C. With a nominal capacitance of 470 µF and a 50 V rating, this polarized can-type capacitor targets demanding power-filtering and energy-storage roles in rugged electronics.

Designed and manufactured for heavy-duty service, the UBX1H471MHL supports automotive applications and other high-reliability systems that require high ripple capability, extended endurance at elevated temperature, and compact radial packaging.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance for bulk energy storage and smoothing on 50 V rails.
• High Temperature Endurance — Rated operating range –55°C to +150°C with specified endurance of 1000 hours at 150°C for the φ12.5 size.
• Ripple Current Performance — Low-frequency ripple current 643.2 mA (120 Hz) and high-frequency ripple current 960 mA (100 kHz) to support high-stress power circuits.
• Leakage Current — Specified leakage current of 705 µA to help predict quiescent losses in power supplies.
• Robust Packaging — Radial, can-style laminated case (φ12.5 × 25 mm length) with 5.0 mm lead spacing and 0.5 mm lead-spacing tolerance for through-hole PCB implementations.
• Automotive Qualification — AEC-Q200 compliant, suitable for automotive electronic applications that require recognized component qualification.
• Compliance & Handling — RoHS compliant; available in bulk (no terminal forming) or bag packing for production or prototype use.

Typical Applications

• Automotive Electronic Control Units (ECUs) — Bulk filtering and energy buffering on 50 V rails in engine, transmission, and body control modules where extended high-temperature life is needed.
• Power Supply Filtering — Smoothing and decoupling in DC–DC converters and intermediate bus capacitors operating in elevated-temperature environments.
• Power Electronics & Motor Drives — Support for ripple absorption and transient energy demands in motor controllers and power modules exposed to automotive-grade thermal stress.

Unique Advantages

• High-temperature reliability: 1000 hours endurance at +150°C (φ12.5) enables predictable long-term performance in thermally harsh environments.
• Automotive-grade qualification: AEC-Q200 compliance provides assurance for integration into automotive systems that require qualified components.
• Strong ripple handling across frequencies: Separate ripple ratings at 120 Hz and 100 kHz (643.2 mA and 960 mA respectively) allow designers to size capacitors based on both low- and high-frequency stress.
• Compact radial form factor: φ12.5 × 25 mm can with 5 mm lead spacing offers a small footprint for through-hole layouts while maintaining substantial capacitance.
• Predictable leakage behavior: Specified leakage current (705 µA) simplifies loss budgeting in standby or low-current conditions.
• Supply and handling flexibility: Available in bulk or bag packing to support prototype runs and volume assembly workflows.

Why Choose UBX1H471MHL?

The UBX1H471MHL combines a high nominal capacitance (470 µF) and a 50 V rating with a laminated can design optimized for +150°C operation. Its AEC-Q200 compliance and endurance specification make it suitable for automotive and other mission-critical embedded power designs that require sustained performance under thermal and ripple stress.

This part is well suited to engineers specifying through-hole bulk capacitance for power rails, DC–DC converter outputs, and motor-drive circuits where space constraints, high ripple currents, and elevated operating temperatures must be balanced against predictable electrical behavior and supply packaging options.
