UBW2A470MPD

The UBW2A470MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UBW series, offering 47 µF capacitance at a 100 V rating. It is designed for high-temperature and long-life applications, with an operating range from –55°C to +135°C and an endurance specification up to 2000 hours at 135°C for the φ10 package size.

This part targets applications that require robust power filtering and energy storage on 100 V rails where elevated temperature performance, endurance and industry-grade reliability are required.

Key Features

• Capacitance & Voltage: 47 µF rated capacitance at 100 V provides energy storage and decoupling for medium-voltage rails.
• High-temperature operation: Specified for –55°C to +135°C, enabling use where elevated ambient or local temperatures are expected.
• Long-life endurance: Endurance rating of 2000 hours at 135°C (for φ10 size) supports sustained performance in demanding thermal conditions.
• Low-frequency and high-frequency ripple handling: Ripple current ratings of 422.1 mA at 120 Hz and 630 mA at 10 kHz provide measurable filtering capability across common power frequencies.
• Electrical performance: Impedance of 550 mΩ and tan δ (DF) of 0.08 (measured at 20°C, 120 Hz for the 100 V rating) for predictable AC behavior.
• Leakage and tolerance: Leakage current listed at 141 µA and capacitance tolerance of –20% to +20% for design margin and verification.
• Radial lead package: φ10 × 16 mm can with 5 mm lead spacing (±0.5 mm) for through-hole assembly and mechanical stability.
• AEC-Q200 rating: Identified with AEC-Q200 in the product specifications for qualification pedigree in critical applications.
• Packaging: Available in bulk (no terminal forming) or bag packing to suit production and prototyping workflows.

Typical Applications

• Automotive electronics: AEC-Q200 rating combined with –55°C to +135°C operation and 2000 h endurance at 135°C make this capacitor suitable for automotive electronic modules that require high-temperature stability.
• 100 V power rails: Use for smoothing, decoupling and local energy storage on 100 V supply lines where a 47 µF capacitance and specified ripple current handling are required.
• High-temperature industrial controllers: Fits designs exposed to elevated temperatures that need reliable long-term capacitor performance and predictable leakage/ripple characteristics.

Unique Advantages

• High-temperature endurance: Rated for continuous performance up to +135°C with documented 2000-hour life at that temperature for the φ10 size, reducing the need for oversized margining.
• Rated for 100 V systems: Directly supports medium-voltage designs without the need for series stacking or specialty arrangements.
• Measured ripple capability: Specified ripple current figures at both low and high frequencies allow designers to quantify thermal and RMS heating for reliable implementation.
• Proven electrical characteristics: Low impedance (550 mΩ) and defined tan δ enable predictable AC performance in filtering and decoupling roles.
• Through-hole robustness: Radial lead, φ10 can and 5 mm lead spacing provide mechanical stability for vibration-prone or hand-soldered assemblies.
• Mass-production availability: Listed as mass production status for stable supply and volume procurement.
