UVR1H331MPD

The UVR1H331MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UVR series. It delivers 330 µF at 50 V in a compact φ10 × 16 mm can with a 5.0 mm lead spacing, designed for general-purpose and entertainment electronics applications.

Engineered for board-level power smoothing and decoupling, the UVR1H331MPD combines a compact footprint with verified ripple current capability and a 2,000-hour endurance rating at 85°C to support reliable operation in space-constrained designs.

Key Features

• Electrical Rating — 330 µF nominal capacitance at 50 V with capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Low-loss Performance — tanδ (dissipation factor) specified as 0.12 at 20°C and 120 Hz (rated voltage 50 V), helping to characterize AC losses in filtering applications.
• Ripple Current Capability — Low-frequency ripple current of 590 mA at 120 Hz and high-frequency ripple current of 885 mA at 10 kHz, supporting effective smoothing under dynamic load conditions.
• Leakage Current — Specified leakage current of 495 µA, enabling predictable bias current behavior in circuits.
• Endurance and Temperature Range — Rated for 2,000 hours at 85°C and specified to operate from –40°C to +85°C, providing defined long-term performance under elevated temperature stress.
• Package and Mounting — Radial-lead, polarized aluminum can with overall size φ10 × 16 mm and lead spacing 5.0 mm (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• RoHS Compliant — Meets RoHS directive requirements as stated for the UVR series.

Typical Applications

• Entertainment Electronics — Designed as part of the UVR standard series for entertainment electronics, suitable for board-level power smoothing and decoupling in consumer audio/video equipment.
• General-Purpose Power Filtering — Used for bulk filtering and smoothing in general-purpose circuits where a compact, through-hole radial capacitor is required.
• Space-Constrained PCB Designs — Compact φ10 × 16 mm can and 5.0 mm lead spacing make this part appropriate for designs that require reduced component footprint while retaining through-hole mounting.

Unique Advantages

• Compact Footprint: φ10 × 16 mm can with 5.0 mm lead spacing minimizes board space while providing 330 µF capacitance.
• Defined Ripple Handling: Specified ripple currents at both 120 Hz and 10 kHz (590 mA and 885 mA) give clear guidance for filtering performance under AC stress.
• Measured Loss Characteristics: tanδ = 0.12 at 20°C/120 Hz (50 V) helps designers estimate AC heating and efficiency in filtering stages.
• Durability at Elevated Temperature: 2,000-hour endurance at 85°C provides a verified baseline for lifetime planning in higher-temperature applications.
• Predictable Leakage: Leakage current specified at 495 µA for dependable bias behavior in power circuits.
• Supply Chain Ready: Mass-production status with RoHS compliance and multiple packing options (bulk or bag) simplifies procurement and assembly planning.
