UVK2V680MHD

The UVK2V680MHD is a radial-lead aluminum electrolytic capacitor in Nichicon's UVK series, sized at φ16×25L with 7.5 mm lead spacing. It delivers 68 µF capacitance at a 350 V rating and is intended for general-purpose power applications that require high-voltage bulk capacitance in a compact through-hole can.

This part combines a 350 V voltage rating, a dissipation factor (tanδ) of 0.25 measured at 20°C/120 Hz, and specified ripple current capability to support DC bus smoothing and energy storage needs while operating across –40°C to +85°C with a 2000 h endurance at 85°C.

Key Features

• Capacitance & Voltage: 68 µF nominal capacitance with a 350 V rated voltage, suitable where compact high-voltage bulk capacitance is required.
• Dissipation Factor: tanδ = 0.25 (measured at 20°C, 120 Hz), providing a defined loss characteristic for thermal and impedance planning.
• Ripple Current Capability: Rated low-frequency ripple current of 400 mA at 120 Hz and high-frequency ripple current of 640 mA at 10 kHz to support filtering and decoupling loads within its ratings.
• Leakage Current: Specified leakage current of 1052 µA following rated voltage application, useful for bias and hold-up calculations.
• Endurance and Temperature Range: 2000 hours at 85°C endurance with operating range from –40°C to +85°C for sustained performance in elevated-temperature environments.
• Package & Mounting: Radial lead, polarized aluminum can in a φ16×25L case with 7.5 mm lead spacing (±0.5 mm); available in bulk/no-terminal-forming and bag packing.
• RoHS Compliance: The UVK series is compliant to the RoHS directive (2011/65/EU, (EU)2015/863) as noted in the series documentation.

Typical Applications

• General Purpose Power Electronics: High-voltage bulk capacitance for filtering, energy storage and DC link smoothing in general-purpose power designs compatible with a 350 V rating.
• Industrial Control Equipment: Provides stable capacitance and specified ripple handling for control power supplies and intermediate bus filtering within the stated temperature and endurance limits.
• Power Supply Modules: Through-hole radial mounting and compact φ16×25L sizing make it suitable for power supply boards requiring polarized aluminum electrolytic capacitance.

Unique Advantages

• 350 V capability: Enables use in higher-voltage DC systems where a compact 68 µF aluminum electrolytic is required.
• Defined dissipation and ripple specs: tanδ = 0.25 and specified ripple currents (400 mA @120 Hz, 640 mA @10 kHz) allow predictable thermal and ripple performance planning.
• Compact radial can: φ16×25L case with 7.5 mm lead spacing provides a smaller footprint while retaining through-hole robustness for serviceability and prototyping.
• Endurance at elevated temperature: Rated for 2000 hours at 85°C, supporting designs that require sustained operation at higher ambient temperatures.
• Clear leakage specification: Leakage current of 1052 µA supplied for accurate bias and standby current budgeting.
• RoHS-compliant series: Conforms to RoHS directive requirements as documented for the UVK family.
