UVK1J680MPD

The UVK1J680MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UVK series, offering a 68 µF capacitance at a 63 V rating in a compact φ8 × 11.5 mm can. Designed for general-purpose through-hole applications, it delivers measured ripple-handling capability and a small footprint for space-constrained board designs.

This part combines a wide operating temperature range (−40 °C to 85 °C), defined endurance (2000 hours at 85 °C), and RoHS compliance—providing a documented, miniature electrolytic solution for power filtering and decoupling tasks where a 63 V rated, polarized capacitor is required.

Key Features

• Capacitance & Voltage: 68 µF nominal capacitance with a 63 V rated voltage and capacitance tolerance of −20% to +20%.
• Radial Lead Through-Hole Package: Radial, can-style package with 3.5 mm lead spacing (±0.5 mm), suitable for standard through-hole assembly and hand or wave soldering workflows.
• Compact Size: Small form factor φ8 × 11.5 mm (L: 1.15 × D: 0.8 cm) for designs with limited board area.
• Ripple Current Performance: Rated low-frequency ripple current 220 mA at 120 Hz and high-frequency ripple current 440 mA at 10 kHz for AC stress handling across a range of switching environments.
• Leakage & Loss Characteristics: Specified leakage current of 128.52 µA and a loss tangent (tanδ) of 0.10 (measured at 20 °C, 120 Hz for the 63 V rating).
• Endurance & Temperature: Lifetime specified as 2000 hours at 85 °C with an operating range of −40 °C to 85 °C.
• Packaging & Production Status: Available in bulk (no terminal forming) or bag packing; product is in mass production and RoHS compliant.

Typical Applications

• Compact Power Supplies: Smoothing and bulk decoupling where a 63 V rated, 68 µF capacitor is required in limited PCB area.
• DC Link and Local Decoupling: Local energy storage and ripple suppression on intermediate rails in converters and regulator circuits.
• Industrial Control Electronics: General-purpose filtering and transient buffering in control modules that operate within −40 °C to 85 °C.

Unique Advantages

• Small footprint for tight layouts: The φ8 × 11.5 mm can provides 68 µF capacitance in a miniature radial package, helping save PCB space.
• Clear ripple specifications: Explicit low- and high-frequency ripple current ratings (220 mA at 120 Hz, 440 mA at 10 kHz) let designers size the part for AC stress in switching environments.
• Documented endurance at elevated temperature: 2000 hours at 85 °C gives a quantifiable expectation for life under continuous elevated-temperature operation.
• Controlled leakage and dissipation: Leakage current of 128.52 µA and tanδ of 0.10 (at 20 °C, 120 Hz) provide clear electrical loss characteristics for thermal and stability assessments.
• Through-hole convenience: Radial leads with standardized 3.5 mm spacing simplify manual assembly and mechanical mounting in legacy or mixed-technology boards.
• Regulatory compliance: RoHS compliant construction supports designs that require lead-free materials.
