UVK1J682MRD

The UVK1J682MRD is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon’s UVK series. It delivers 6.8 mF (6800 µF) capacitance at a 63 V rating in a compact φ25 × 50 mm can with 12.5 mm lead spacing.

Designed for general‑purpose use, the part offers a broad operating temperature range (−40 °C to 85 °C), defined endurance (2000 hours at 85 °C), measurable ripple current capability, and RoHS compliance. Status: End Of Life.

Key Features

• Capacitance & Tolerance — 6800 µF nominal capacitance with tolerance of −20% to +20% for predictable bulk storage performance.
• Rated Voltage — 63 V DC rating suitable where mid‑voltage energy storage is required.
• Package & Mounting — Radial lead, can‑style package (φ25 × 50 mm) with 12.5 mm lead spacing for through‑hole mounting.
• Ripple Current Performance — Low‑frequency ripple current 3.9 A (120 Hz) and high‑frequency ripple current 4.485 A (10 kHz), specified to guide thermal and lifetime considerations.
• Leakage Current — Specified leakage current of 12,852 µA for initial electrical characterization and design margining.
• Loss Angle (tan δ) — tan δ = 0.2 measured at 20 °C, 120 Hz for dissipation guidance during design.
• Temperature & Endurance — Operating range −40 °C to 85 °C with endurance of 2000 hours at 85 °C under rated voltage.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to match assembly preferences.
• Compliance — RoHS compliant per supplied product data.
• Polarized — Polar capacitor for DC applications requiring correct polarity handling.

Typical Applications

• General Purpose — Intended for general‑purpose capacitor roles where a 6.8 mF, 63 V radial electrolytic is required and designers need defined ripple and endurance specifications.
• General Purpose — Suitable for through‑hole designs that require bulk capacitance in a compact φ25 × 50 mm can with 12.5 mm lead spacing.
• General Purpose — Applicable when RoHS compliance, specified leakage, and quantified tan δ at 120 Hz are needed for electrical characterization.

Unique Advantages

• High Bulk Capacitance in a Miniature Can — 6.8 mF in a φ25 × 50 mm package provides significant energy storage while conserving board area compared to larger form factors.
• Clear Ripple Current Ratings — Both 120 Hz and 10 kHz ripple current values are specified (3.9 A and 4.485 A respectively), enabling more accurate thermal and lifetime planning.
• Defined Endurance — Lifetime characterization of 2000 hours at 85 °C under rated voltage helps set expectations for long‑term performance in elevated‑temperature environments.
• Measured Dissipation — Specified tan δ (0.2 at 20 °C, 120 Hz) provides designers with dissipation data for AC and ripple loss calculations.
• Through‑Hole Mounting Flexibility — Radial lead form with 12.5 mm lead spacing and bulk/bag packing options accommodates manual and automated through‑hole assembly workflows.
• Regulatory Compliance — RoHS compliance supports environmental requirements for many projects.
