UBW1H330MPD

The UBW1H330MPD is a radial lead aluminum electrolytic capacitor from Nichicon's UBW series. It delivers 33 µF capacitance at a 50 V rating in a compact φ8 × 11.5 mm can with radial leads and 3.5 mm lead spacing.

Engineered for high-temperature environments and long life, this AEC-Q200 rated component is intended for demanding automotive-grade applications that require stable performance across -55°C to +135°C and endurance up to 1000 hours at 135°C.

Key Features

• Electrical Characteristics — 33 µF nominal capacitance with ±20% tolerance, rated voltage 50 V, and polarization suitable for DC applications.
• Low Loss — Tangent of loss angle (tan δ) specified at 0.10 (120 Hz, 20°C, 50 V) for controlled dissipation and predictable AC performance.
• Ripple Current Performance — Low-frequency ripple current 201 mA (120 Hz) and high-frequency ripple current 300 mA (10 kHz) to support power supply ripple handling in compact assemblies.
• Leakage Current — Specified leakage current of 49.5 µA for predictable leakage behavior after voltage application.
• High-Temperature Endurance — Rated for operation from -55°C to +135°C with a specified life of 1000 hours at 135°C under rated DC bias plus ripple current.
• Compact Radial Package — φ8 can body, 11.5 mm length, 3.5 mm lead spacing (±0.5 mm) in a radial lead form factor for through-hole mounting and easy placement.
• Automotive Qualification — AEC-Q200 rating and listed application for automotive use, supporting deployment in vehicle systems.
• Availability & Packaging — Mass production status with bulk (no terminal forming) and bag packing options for production assembly planning.

Typical Applications

• Automotive Electronics — Suitable for automotive electronic modules where AEC-Q200 qualification and a -55°C to +135°C operating range are required.
• High-Temperature Power Systems — Designed for power assemblies that require capacitor endurance at elevated temperatures (1000 hours at 135°C).
• Through-Hole Power Filtering — Compact radial package provides a space-efficient option for through-hole smoothing and filtering in constrained PCB layouts.

Unique Advantages

• Automotive-grade reliability: AEC-Q200 rating and extended temperature range support deployment in regulated vehicle environments.
• High-temperature endurance: Rated life of 1000 hours at 135°C provides predictable aging behavior for long-term designs.
• Balanced ripple handling: Defined low- and high-frequency ripple current specifications facilitate component selection for mixed-frequency power designs.
• Low dissipation factor: tan δ = 0.10 at 50 V (120 Hz, 20°C) helps minimize power loss in AC conditions.
• Compact through-hole form: φ8 × 11.5 mm can with 3.5 mm lead spacing offers a small footprint for space-constrained assemblies.
• Production-ready packaging: Mass production availability with bulk/bag packing simplifies procurement and assembly planning.
