UVR1A331MED

The UVR1A331MED is a Nichicon UVR series aluminum electrolytic capacitor in a radial‑lead, can package. It provides 330 µF capacitance at a 10 V rating with ±20% tolerance and is offered in a compact φ6.3×11 mm form factor with 2.5 mm lead spacing.

Designed for general‑purpose and entertainment electronics applications, the part delivers measurable ripple handling, low leakage, and a defined endurance rating for predictable performance in low‑voltage power filtering and decoupling roles.

Key Features

• Electrical Performance — 330 µF capacitance at 10 V with ±20% tolerance; tangent of loss angle (tan δ) 0.24 measured at 20°C, 120 Hz.
• Ripple and Leakage — Rated ripple current of 290 mA at 120 Hz (low frequency) and 435 mA at 10 kHz (high frequency); leakage current specified at 99 µA.
• Reliability & Endurance — Endurance rating of 2000 hours at 85°C with performance requirements for capacitance change, tan δ and leakage current after the test.
• Operating Range — Specified operating temperature range from −40°C to +85°C for use across typical consumer and general‑purpose environments.
• Package & Mounting — Radial lead, can package with φ6.3×11 mm dimensions, 2.5 mm lead spacing and bulk/bag packing (no terminal forming).
• Compliance & Identification — RoHS‑compliant and marked with white lettering on a black sleeve consistent with the UVR series.
• Polarized — Polarized aluminum electrolytic capacitor suitable for DC filtering and energy storage functions.
• Product Status — End Of Life.

Typical Applications

• Home and Entertainment Electronics — Smoothing and filtering in low‑voltage power supplies for consumer audio, set‑top boxes and similar devices consistent with the UVR series focus.
• Power Rail Decoupling — Bulk decoupling and stabilization on 10 V and lower DC rails where a compact radial through‑hole capacitor is required.
• Control and Interface Circuits — Local energy buffering and ripple suppression in small control boards and interface modules.

Unique Advantages

• Compact high capacitance: 330 µF in a φ6.3×11 mm can enables significant energy storage in space‑constrained through‑hole designs.
• Measured ripple capability: Distinct low‑ and high‑frequency ripple current ratings (290 mA @120 Hz, 435 mA @10 kHz) allow designers to assess suitability for both mains‑frequency smoothing and higher‑frequency switching environments.
• Low leakage current: Specified 99 µA leakage helps maintain efficiency and predictable discharge behavior in DC circuits.
• Rated endurance at elevated temperature: 2000 hours at 85°C gives a defined lifecycle metric for reliability planning in consumer and general‑purpose products.
• Radial through‑hole form factor: 2.5 mm lead spacing and standard can package simplify assembly and replacement in legacy and serviceable designs.
• RoHS compliant: Complies with RoHS directive for use in assemblies requiring restricted‑substance adherence.
