UVR1E331MPD

The UVR1E331MPD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UVR series, rated 330 µF at 25 V with ±20% tolerance. Designed as a compact, general-purpose solution, it targets consumer and entertainment electronics where space-efficient smoothing, decoupling and bulk energy storage are required.

Key value lies in a small φ10 × 12.5 mm can, robust ripple capability (440 mA at 120 Hz / 660 mA at 10 kHz), and a 2000-hour endurance at 85°C—balanced performance for mass-production assemblies and repair/prototyping workflows.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance at a rated voltage of 25 V with ±20% tolerance for predictable bulk storage and decoupling.
• Packaging & Mounting — Radial lead can (φ10 × 12.5 mm) with 5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for production and prototype use.
• Ripple Current Performance — Low-frequency ripple current 440 mA at 120 Hz and high-frequency ripple current 660 mA at 10 kHz to support smoothing and transient loading in power rails.
• Electrical Losses — Tangent of loss angle (tan δ) 0.16 measured at 20°C and 120 Hz, enabling designers to assess ESR-related heating and efficiency.
• Leakage Current — Specified leakage current of 247.5 µA for predictable stand-by and bias behavior after voltage application.
• Reliability & Lifetime — Endurance rated 2000 hours at 85°C with the specified voltage applied; performance restored to 20°C meets endurance criteria for capacitance, tan δ and leakage.
• Operating Temperature — Rated for use from −40°C to +85°C to cover a wide range of consumer and industrial ambient conditions.
• Compliance & Production Status — RoHS compliant and in mass production, backed by Nichicon’s UVR series design and manufacturing.

Typical Applications

• Entertainment Electronics — Bulk smoothing and power-rail decoupling in audio, set-top and display electronics where the UVR series is commonly applied.
• Consumer Power Supplies — Filtering and transient support on DC output rails, leveraging the part’s ripple current ratings and compact can size.
• General-Purpose Electronics — Decoupling and energy storage in a wide range of boards and modules that require radial-lead mounting.
• Prototyping & Repair — Bulk and bag packing options make the part convenient for bench work, board-level replacements, and low-volume assembly.

Unique Advantages

• Compact radial form factor — φ10 × 12.5 mm can with 5 mm lead spacing enables dense PCB layouts without sacrificing capacitance.
• High ripple tolerance — 440 mA (120 Hz) and 660 mA (10 kHz) ripple ratings reduce stress in power-supply filtering and transient events.
• Clear electrical characterization — Specified tan δ (0.16 at 20°C/120 Hz) and quantified leakage current (247.5 µA) help designers model ESR losses and standby behavior.
• Proven endurance — 2000 hours at 85°C provides a measurable reliability baseline for thermal-stressed applications.
• RoHS compliance — Meets environmental directives for lead-free production environments.
• Production-ready availability — Mass-production status supports volume builds and repeatable procurement.
