UBX1V331MHL

The UBX1V331MHL is a high-reliability miniature aluminum electrolytic capacitor in a radial-lead can, part of Nichicon's UBX series. It delivers 330 µF capacitance at a 35 V rating with polarized construction and a ±20% tolerance (measured at 120 Hz, 20°C).

Designed for demanding electronics, this capacitor targets automotive and heavy-duty applications where elevated temperature endurance, ripple-current capability and long life are required. Key value propositions include operation up to +150°C, AEC-Q200 qualification and long-term endurance under DC bias plus rated ripple current.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at 35 V with ±20% tolerance (120 Hz, 20°C).
• High-Temperature Endurance — Rated for operation from −55°C to +150°C with an endurance specification of 2000 hours at 150°C under rated conditions.
• Loss Characteristics — Tangent of loss angle (tanδ) 0.12 (max.) at 20°C, 120 Hz for predictable AC performance.
• Ripple Current Handling — Low-frequency ripple current 536 mA (120 Hz) and high-frequency ripple current 800 mA (100 kHz) for power-supply smoothing and switching applications.
• Leakage Current — Specified leakage current of 346.5 µA for predictable standby and bias behavior.
• Package & Mounting — Radial-lead can, size φ16 × 25L with 7.5 mm lead spacing; supplied in bulk (no terminal forming) or bag packing.
• Reliability & Compliance — High-reliability UBX series construction, AEC-Q200 rated and RoHS compliant.
• Polarized — Electrolytic, polarized device for DC power applications.

Typical Applications

• Automotive electronics — Power smoothing and decoupling in automotive modules where operation to +150°C and AEC-Q200 qualification are required.
• Power supply filtering — Bulk and output filtering for DC-DC converters and power rails that demand high ripple-current capability.
• Industrial controls — Energy buffering and decoupling in heavy-duty electronics exposed to elevated temperatures and continuous load.

Unique Advantages

• High-temperature durability: Endurance rated to 2000 hours at 150°C providing stability in thermally stressed assemblies.
• Automotive-grade qualification: AEC-Q200 rating supports use in automotive and similarly demanding applications.
• Strong ripple-current capacity: 800 mA at 100 kHz (high frequency) and 536 mA at 120 Hz (low frequency) reduce thermal stress and improve lifetime under switching loads.
• Predictable electrical behavior: Low tanδ (0.12) and specified leakage current enable reliable filtering and power-decoupling performance.
• Practical radial package: φ16 can with 7.5 mm lead spacing simplifies through-hole assembly and retrofit into established PCB layouts.
• Regulatory compliance: RoHS compliant for use in designs requiring environmental directive conformance.
