UVR1J331MPD

The UVR1J331MPD is a miniature aluminum electrolytic capacitor from Nichicon's UVR series, delivered in a radial‑lead, can package. It provides 330 µF capacitance at a 63 V rating and is targeted for general-purpose and entertainment electronics applications where compact power filtering and smoothing are required.

Key performance attributes include a wide operating temperature range (‑40°C to +85°C), 2000‑hour endurance at 85°C, measurable low and high frequency ripple current capability, and RoHS compliance—making it suitable for compact PCB power rails and decoupling tasks up to 63 V.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 63 V and capacitance tolerance of ±20% (‑20%~20%).
• Loss Tangent (tan δ) — tanδ = 0.1 measured at 20°C, 120 Hz, providing predictable dissipation characteristics for AC performance evaluations.
• Ripple Current Performance — Low‑frequency ripple current of 710 mA at 120 Hz and high‑frequency ripple current of 1.065 A at 10 kHz to support power supply filtering across a range of switching and line‑frequency environments.
• Leakage Current — Specified leakage current of 623.7 µA after rated voltage application, enabling straightforward bias‑current budgeting in designs.
• Endurance & Temperature Range — Rated for 2000 hours at 85°C with operating range from ‑40°C to +85°C, supporting long‑term stability in ambient and elevated temperature conditions.
• Compact Radial Package — 10 mm diameter × 20 mm length can with 5 mm lead spacing (tolerance ±0.5 mm), radial lead mounting for through‑hole assembly and straightforward replacement/repair.
• Packaging & Compliance — Available in bulk or bag packing (no terminal forming) and compliant with RoHS requirements.

Typical Applications

• Entertainment Electronics — Used for power supply smoothing and bulk decoupling in consumer entertainment devices where the UVR series is specified.
• PCB Power Rails — Provides bulk capacitance and ripple handling for DC rails up to 63 V in general‑purpose electronic circuits.
• Switching Power Supplies — Supports filtering at both line frequency and switching frequencies, leveraging specified ripple current ratings at 120 Hz and 10 kHz.

Unique Advantages

• Compact, high‑capacitance solution — 330 µF in a 10 mm × 20 mm can minimizes PCB footprint while delivering substantial bulk capacitance.
• Dual‑frequency ripple capability — Specified ripple current at both 120 Hz and 10 kHz enables confident use across line‑frequency and switching applications.
• Durability at elevated temperature — 2000 hours endurance at 85°C provides a predictable life metric for thermal‑stress planning.
• Engineered dissipation characteristics — tanδ specified at 20°C, 120 Hz supports loss and thermal calculations during design validation.
• Through‑hole radial mounting — 5 mm lead spacing and radial can package simplify prototyping, repair, and mechanical retention on PCBs.
• RoHS compliant — Meets environmental directive requirements for restricted substances.
