UBW1J331MHD

The UBW1J331MHD is a high‑reliability, miniature aluminum electrolytic capacitor from Nichicon's UBW series. It is a radial‑lead, polarized capacitor rated at 330 µF and 63 V, designed for continuous operation up to +135°C with long endurance.

Targeted for automotive and other high‑temperature environments, this part combines a compact φ12.5 × 25 mm can with a long lifetime and AEC‑Q200 qualification to meet demanding system requirements where temperature resilience and ripple handling are critical.

Key Features

• Electrical Performance 330 µF capacitance with ±20% tolerance and an impedance of 120 mΩ provide stable bulk capacitance and low-loss behavior at 120 Hz, tanδ = 0.1 (20°C, 120 Hz).
• Voltage & Ripple Capability Rated for 63 V with low‑frequency ripple current of 864.3 mA (120 Hz) and high‑frequency ripple current of 1.29 A (10 kHz), supporting sustained ripple handling in power applications.
• High‑Temperature Endurance Operating temperature range −55°C to +135°C and an endurance rating of 3000 hours at 135°C, enabling reliable performance in elevated‑temperature installations.
• Automotive Qualification AEC‑Q200 rating indicates the unit meets automotive reliability screening for demanding vehicle electronics.
• Compact Radial Package φ12.5 mm diameter × 25 mm length can with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through‑hole assembly; lead‑wire and sleeve options consistent with UBW series construction.
• Leakage and Loss Characteristics Low leakage current (specified 623.7 µA for this part) and defined tanδ limits support predictable behavior over life and temperature.
• Availability & Packaging Supplied in bulk or bag packing (no terminal forming) and listed as mass production for reliable supply chain planning.

Typical Applications

• Automotive power electronics — Bulk energy storage and smoothing in vehicle power rails where elevated ambient temperatures and long life are required.
• Electronic control units (ECUs) — Power rail stabilization and ripple suppression for control modules designed for harsh environments.
• Infotainment and telematics — Supporting power conditioning in modules that must tolerate higher operating temperatures.

Unique Advantages

• High‑temperature capability: −55°C to +135°C rating and 3000 h endurance at 135°C provide assurance for long life in hot environments.
• Automotive‑grade reliability: AEC‑Q200 qualification supports use in vehicle electronics subject to automotive screening and quality expectations.
• Strong ripple performance: Specified ripple currents of 864.3 mA (120 Hz) and 1.29 A (10 kHz) combined with low impedance enable effective suppression of power supply noise.
• Compact footprint: 330 µF capacitance in a φ12.5 × 25 mm radial can saves board space while delivering bulk capacitance for demanding circuits.
• Production readiness: Mass production status and standard bulk/bag packaging simplify procurement and assembly planning.
