UVR2D331MRD6

The UVR2D331MRD6 from Nichicon is a radial‑lead aluminum electrolytic capacitor in the UVR miniature series, engineered for general‑purpose and entertainment electronics power applications. It delivers 330 µF capacitance at a 200 V rated voltage in a compact φ25 × 30 mm can, providing bulk energy storage and smoothing in board‑mounted designs.

Designed for reliable performance across a broad operating range, this polarized capacitor supports ripple currents above 1 A, a measured dissipation factor of 0.2 (20°C, 120 Hz), and an endurance rating of 2000 hours at 85°C for stable electrical characteristics over time.

Key Features

• Capacitance & Tolerance — 330 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C), suitable for bulk filtering and decoupling tasks.
• Rated Voltage — 200 V DC rating for higher‑voltage power rails and supply filtering.
• Dissipation Factor (tan δ) — 0.2 measured at 20°C, 120 Hz, providing a defined loss characteristic for design calculations.
• Ripple Current Handling — Low‑frequency ripple current of 1.09 A (120 Hz) and high‑frequency ripple current of 1.254 A (10 kHz), enabling effective ripple suppression across frequencies.
• Leakage Current — Specified leakage current 2740 µA for initial electrical assessments and margining.
• Temperature & Endurance — Operating range −40°C to +85°C with endurance specified as 2000 hours at 85°C under rated voltage.
• Package & Mounting — Radial, can‑style package (φ25 × 30 mm) with 12.5 mm lead spacing (±0.5 mm) for through‑hole PCB mounting and straightforward assembly.
• Polarized — Designed for polarized applications; clear polarity marking is provided (white letters on black sleeve as per series marking).
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit assembly and handling requirements.
• RoHS Compliant — Meets RoHS directive requirements for material compliance.

Typical Applications

• Entertainment Electronics — Bulk filtering and power smoothing in audio, video and consumer entertainment assemblies where the UVR series is commonly applied.
• General‑Purpose Power Supplies — Energy storage and ripple suppression on intermediate and high‑voltage DC rails up to 200 V.
• Board‑Mounted Power Filtering — Through‑hole radial mounting for designs that require robust leaded capacitors for manual or wave solder assembly.

Unique Advantages

• High‑voltage bulk capacitance: 330 µF at 200 V provides substantial energy storage for higher voltage rails without large package footprint.
• Robust ripple capability: Rated ripple currents above 1 A at both 120 Hz and 10 kHz reduce heat rise and improve ripple attenuation across common power frequencies.
• Defined loss characterization: Tan δ = 0.2 at 120 Hz and 20°C gives predictable AC loss for accurate thermal and performance margins.
• Wide operating temperature and proven endurance: −40°C to +85°C range with 2000 hours endurance at 85°C supports stable long‑term operation in many environments.
• Clear polarity marking and radial can package: White-on-black sleeve marking and standard lead spacing simplify assembly and polarity verification in production.
• Regulatory compliance: RoHS compliance helps meet material restrictions for many commercial products.
