UBW1J471MHD

The UBW1J471MHD is a radial lead aluminum electrolytic capacitor from Nichicon’s UBW series. It delivers 470 µF capacitance at a 63 V rating in a compact φ12.5 × 30.5 mm can with 5.0 mm lead spacing.

Designed for high-temperature, long-life applications, this AEC‑Q200 rated, polarized capacitor supports operation from −55°C to +135°C with a rated endurance of 3000 hours at +135°C, making it suited to demanding environments that require stable filtering and energy storage over extended life cycles.

Key Features

• Capacitance & Tolerance — 470 µF nominal capacitance with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 63 V working voltage for mid-voltage power applications.
• High Temperature Endurance — Operates from −55°C to +135°C with a specified lifetime of 3000 hours at 135°C.
• Low Impedance — Specified impedance of 97 mΩ to support low-loss filtering and decoupling.
• Ripple Current Capability — Low-frequency ripple current 978.2 mA at 120 Hz and high-frequency ripple current 1.46 A at 10 kHz, enabling reliable performance under AC stress.
• Leakage & Dissipation — Leakage current of 888.3 µA and tan δ (DF) of 0.10 at 120 Hz, 20°C.
• Package & Mounting — Radial lead can (φ12.5 × 30.5 mm) with 5.0 mm lead spacing; available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• AEC‑Q200 Rated — Meets AEC‑Q200 specification for passive components intended for automotive applications.

Typical Applications

• Automotive electronics — AEC‑Q200 rating plus −55°C to +135°C temperature range and 3000 h endurance make the UBW1J471MHD appropriate for vehicle electronics exposed to high temperature and long duty cycles.
• High-temperature power modules — Low impedance and substantial ripple current capacity support smoothing and decoupling in power modules operating at elevated temperatures.
• Long-life control systems — The specified 3000-hour endurance at 135°C suits control and monitoring electronics where component longevity under thermal stress is required.

Unique Advantages

• High-temperature reliability — Specified operation up to +135°C and 3000 h endurance reduce the need for over-design in thermally demanding systems.
• Automotive-grade qualification — AEC‑Q200 rating provides an assurance of suitability for automotive component-level requirements.
• Robust ripple handling — Combined low-frequency and high-frequency ripple current ratings enable use across a range of switching and linear power conditions.
• Compact radial form factor — φ12.5 × 30.5 mm can with 5.0 mm lead spacing supports compact board layouts while providing substantial capacitance.
• Predictable electrical behavior — Low impedance (97 mΩ) and defined tan δ at 120 Hz help designers quantify filtering and decoupling performance.
• Flexible packaging — Available in bulk (no terminal forming) or bag packing to accommodate different assembly workflows.
