UVR1J332MRD

The UVR1J332MRD is a radial‑lead aluminum electrolytic capacitor from Nichicon’s UVR series, offered as a compact, high‑capacitance option for general‑purpose electronics. It delivers 3.3 mF nominal capacitance at a 63 V rating in a φ20 × 40 mm can package with radial leads and 10 mm lead spacing.

Designed as part of the UVR miniature series (standard for entertainment electronics), this capacitor targets applications that require bulk energy storage and ripple handling within an operating range of −40°C to +85°C and an endurance rating of 2000 hours at 85°C.

Key Features

• Capacitance & Voltage: 3.3 mF nominal capacitance with ±20% tolerance at a 63 V rated voltage for bulk energy storage.
• Ripple Performance: Specified low‑frequency ripple current 2.7 A (120 Hz) and high‑frequency ripple current 3.105 A (10 kHz) to support smoothing and decoupling in power circuits.
• Leakage Current: Defined leakage current of 6,237 μA, provided as a measured parameter for design verification and power‑budget calculations.
• Endurance & Temperature Range: Rated for 2,000 hours at 85°C and continuous operation from −40°C to +85°C for stable performance in standard environmental conditions.
• Package & Mounting: Radial can style (φ20 × 40 mm) with 10 mm lead spacing (±0.5 mm) and radial leads for through‑hole mounting; available in bulk (no terminal forming) or bag packing.
• RoHS Compliant: Meets RoHS requirements as indicated for the UVR series.

Typical Applications

• Entertainment electronics: Suited for supply decoupling and energy storage in consumer audio/video equipment as part of the UVR standard series for this market segment.
• General‑purpose power supplies: Bulk capacitance for smoothing and hold‑up in DC power rails where a 63 V rating is required.
• Control and industrial electronics: Energy buffering and ripple attenuation in general‑purpose control circuits that operate within the −40°C to +85°C range.

Unique Advantages

• High capacitance in a compact can: 3.3 mF in a φ20 × 40 mm radial package provides substantial energy storage while preserving board space compared with multiple smaller parts.
• Measurable ripple capability: Explicit low‑ and high‑frequency ripple current specifications (2.7 A @120 Hz, 3.105 A @10 kHz) help match the capacitor to power‑stage requirements.
• Endurance data for design confidence: 2,000 hours at 85°C endurance rating supports expected life calculations and thermal stress planning.
• Through‑hole robustness: Radial lead can and defined 10 mm lead spacing simplify placement and soldering for prototyping and legacy assembly lines.
• Regulatory compliance: RoHS compliance aligns with modern environmental requirements for electronic assemblies.
