UBW1V331MPD

The UBW1V331MPD is a radial-lead aluminum electrolytic capacitor in the Nichicon UBW series, specified for high-temperature, long-life operation. It delivers 330 µF capacitance at a 35 V rating in a compact φ10 × 20 mm can with 5 mm lead spacing.

Designed for demanding environments, the part combines a wide operating temperature range and AEC-Q200 rating with measurable ripple-current capability and low impedance to support robust power and energy-storage needs in industrial and automotive electronics.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance with ±20% tolerance at 35 V, providing bulk energy storage in a compact radial can.
• High‑Temperature Endurance — Rated for operation from −55 °C to +135 °C with a specified endurance of 2000 hours at +135 °C for the φ10 size.
• Ripple‑Current Performance — Low-frequency ripple current 636.5 mA (120 Hz) and high-frequency ripple current 950 mA (10 kHz) to handle AC content under load.
• Low Impedance — 75 mΩ impedance to minimize voltage drop under transient and steady ripple conditions.
• Leakage Current — Specified leakage current of 346.5 µA, suitable for many power and hold-up applications where controlled leakage is required.
• Package & Mounting — Radial-lead can (φ10 × 20 mm), lead spacing 5.0 mm (±0.5 mm) for through-hole or hand-assembly applications; available bulk or bag packing (no terminal forming).
• Automotive-Grade Qualification — Listed with AEC‑Q200 rating, indicating qualification for demanding automotive and high-reliability applications.

Typical Applications

• Automotive electronics — Suitable where AEC‑Q200 qualification and operation across −55 °C to +135 °C are required for vehicle systems and modules.
• High-temperature, long-life modules — Designed for assemblies that require 2000 hours of endurance at +135 °C without exceeding specified performance limits.
• Through-hole power assemblies — Radial-lead can and 5 mm lead spacing enable reliable mounting in through-hole or mixed-technology boards for power filtering and energy storage.

Unique Advantages

• Temperature-resilient design: Endurance rating of 2000 h at +135 °C and an operating range from −55 °C to +135 °C provide predictable behavior in extreme environments.
• Measurable ripple handling: Specified ripple currents at both 120 Hz and 10 kHz give designers clear electrical limits for AC-loaded applications.
• Low impedance for transient response: 75 mΩ impedance helps reduce voltage sag under load and supports stable power delivery.
• Automotive qualification: AEC‑Q200 listing supports usage in regulated automotive and high-reliability systems that demand component-level qualification.
• Compact, industry-standard package: φ10 × 20 mm radial can with 5 mm lead spacing fits common through-hole layouts and assembly processes.
• Production-ready availability: Offered in bulk or bag packing and listed as mass production, streamlining procurement and assembly planning.
