UVK2W680MHD

The UVK2W680MHD is a radial-lead aluminum electrolytic capacitor offering 68 µF capacitance at a 450 V rating in a compact φ18 × 35.5 mm can. It is part of Nichicon’s UVK series of miniature-sized electrolytics and is specified for general-purpose applications where a high-voltage, compact polarized capacitor is required.

Designed for durability in elevated temperatures, this part delivers a 2000-hour endurance at 85°C and provides measurable low- and high-frequency ripple current capabilities, making it suitable for a range of general-purpose circuit designs.

Key Features

• Rated Capacitance & Tolerance — 68 µF nominal capacitance with tolerance of −20% to +20% at 120 Hz, 20°C.
• High Voltage Rating — 450 V rated voltage for applications requiring higher DC voltage capability.
• Dissipation Factor (tan δ) — tanδ of 0.25 measured at 20°C and 120 Hz, useful for assessing loss characteristics in circuit design.
• Ripple Current Capability — Low-frequency ripple current of 260 mA at 120 Hz and high-frequency ripple current of 416 mA at 10 kHz, supporting both LF and HF filtering needs.
• Leakage Current — Specified leakage current of 1324 µA after rated voltage application, for predictable quiescent behavior.
• Compact Radial Can Package — φ18 × 35.5 mm radial can with 7.5 mm lead spacing (±0.5 mm), available in Bulk (no terminal forming) or Bag packing.
• Operating Temperature & Endurance — Rated for −25°C to +85°C with a life specification of 2000 hours at 85°C.
• RoHS Compliant — Compliant with RoHS requirements as stated in the UVK series documentation.

Typical Applications

• General-Purpose Power Applications — For circuits that require a 68 µF, 450 V polarized capacitor for DC filtering or smoothing where a compact radial can is preferred.
• High-Voltage General-Purpose Circuits — Suitable for designs operating up to 450 V with requirements for specified leakage current and dissipation factor.
• Compact Equipment Designs — Fits miniature-sized requirements where one-rank smaller case dimensions help reduce board space while maintaining 2000-hour endurance at 85°C.

Unique Advantages

• High Voltage Capability: 450 V rating enables use in higher-voltage general-purpose circuits without series-up configurations.
• Miniature Can Size: φ18 × 35.5 mm package provides a smaller footprint consistent with the UVK series’ miniature sizing.
• Defined Endurance: 2000 hours at 85°C delivers an explicit reliability baseline for thermal endurance planning.
• Measured Ripple Performance: Specified low- and high-frequency ripple currents (260 mA at 120 Hz, 416 mA at 10 kHz) enable clear selection for filtering requirements across frequency ranges.
• Polarized Radial Lead Form: Standard radial lead configuration with 7.5 mm lead spacing (±0.5 mm) simplifies through-hole assembly and mounting choices; available in bulk or bag packing for flexible procurement.
• RoHS Compliance: Declared RoHS compliance supports regulatory requirements for restricted substances.
