UBW1A332MHD

The UBW1A332MHD is a Nichicon UBW-series aluminum electrolytic capacitor in a radial-can package, specified at 3.3 mF (3300 µF) and 10 V. It combines high capacitance density with a wide operating temperature range and long endurance for designs exposed to elevated temperatures.

Engineered for applications demanding high ripple capability and extended life, this radial-leaded capacitor is suitable for automotive and other harsh-environment systems that require AEC-Q200-rated components and sustained performance up to +135°C.

Key Features

• Capacitance & Voltage — 3300 µF nominal capacitance at a 10 V rating with tolerance of -20% to +20% for bulk energy storage and smoothing.
• High-temperature endurance — Rated for operation from -55°C to +135°C with a specified endurance of 3000 hours at 135°C.
• Low impedance — Impedance specified at 24 mΩ to support high-current demands and reduce voltage ripple under load.
• High ripple current capability — Low-frequency ripple current of 1.541 A at 120 Hz and high-frequency ripple current of 2.3 A at 10 kHz for demanding power applications.
• Loss characteristics — Tangent of loss angle (tan δ) listed as 0.24 (measured at 20°C, 120 Hz), supporting predictable AC loss behavior.
• Mechanical & packaging — Radial lead, φ16 × 25 mm can with 7.5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing; product is in mass production.
• Reliability — Specified leakage current 990 µA and AEC-Q200 rating for use in regulated, high-reliability assemblies.

Typical Applications

• Automotive electronic modules — AEC-Q200-rated component for modules that require capacitors capable of operating to +135°C and sustaining long-term endurance.
• High-temperature power assemblies — Bulk energy storage and smoothing in power stages where extended life at elevated temperature is required.
• High-ripple DC circuits — Circuits with significant ripple or switching noise benefit from the device’s specified low impedance and high ripple current capability.

Unique Advantages

• Extended high-temperature life: 3000 hours endurance at 135°C enables longer service intervals in thermally demanding environments.
• Robust ripple performance: Specified ripple currents at both low (1.541 A at 120 Hz) and high frequency (2.3 A at 10 kHz) support a wide range of switching and linear power applications.
• Low ESR/impedance: 24 mΩ impedance helps minimize voltage drop and heating under load, improving system stability.
• Automotive-grade qualification: AEC-Q200 rating provides a recognized reliability baseline for automotive and other high-reliability markets.
• Compact radial-can form factor: φ16 × 25 mm package with standard 7.5 mm lead spacing simplifies PCB layout for through-hole assemblies while delivering high capacitance.
