UVK2E680MHD

The UVK2E680MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UVK series, specified at 68 µF and 250 V. It is a miniature-sized, polarized through-hole capacitor designed for general-purpose electronic equipment.

Key characteristics include a compact φ16 × 25 mm can, 7.5 mm lead spacing, a wide operating temperature range of –40 °C to +85 °C, and a rated endurance of 2000 hours at 85 °C, making it suitable for applications that require reliable filtering and decoupling in constrained layouts.

Key Features

• Electrical Performance 68 µF nominal capacitance with ±20% tolerance and a rated voltage of 250 V; tangent of loss angle (tanδ) 0.20 measured at 20 °C, 120 Hz.
• Ripple Current Capability Specified low-frequency ripple current of 380 mA at 120 Hz and high-frequency ripple current of 608 mA at 10 kHz for handling AC components in power circuits.
• Low Leakage Leakage current listed at 780 µA, supporting stable bias performance after application of rated voltage.
• Reliability & Endurance Rated for 2000 hours at 85 °C with defined limits for capacitance change (within ±20%), tanδ (≤ 200% of initial), and leakage current (≤ initial specified value) after endurance testing.
• Compact Radial Package Miniature φ16 × 25 mm can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assembly; available in bulk or bag packing.
• Regulatory Compliance RoHS compliant as part of the Nichicon UVK series.

Typical Applications

• General-purpose electronic equipment — Suitable where a compact radial aluminum electrolytic capacitor is required for power and signal conditioning in through-hole designs.
• Power supply filtering — Used for smoothing and filtering in power circuits up to 250 V where moderate ripple current handling and low leakage are needed.
• Decoupling and bulk storage — Provides local energy storage and decoupling in PCB assemblies requiring a durable capacitor with defined endurance at elevated temperature.

Unique Advantages

• High voltage rating: 250 V rating enables use in higher-voltage power circuits while maintaining compact size.
• Balanced ripple performance: Specified ripple current values at both 120 Hz and 10 kHz (380 mA and 608 mA) offer predictable behavior across common frequency ranges.
• Compact miniature footprint: φ16 × 25 mm can with 7.5 mm lead spacing saves board area compared with larger radial types.
• Endurance-tested: 2000-hour life at 85 °C with quantified limits on capacitance, tanδ, and leakage current for predictable long-term behavior.
• Low leakage: 780 µA leakage current supports stable bias and reduces standby losses in many designs.
• RoHS compliant: Meets RoHS directive requirements as part of the Nichicon UVK family.
