UCY2C680MHD3

The UCY2C680MHD3 is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can from Nichicon’s UCY series. It is a polarized, radial-lead device specified for power applications where compact size, high ripple capability and long operational life at elevated temperature are required.

Designed for automotive and general power-supply use, the device combines a 68 µF capacitance at 160 V rating with a long life rating of 10,000 hours at 105°C, delivering stable performance across -40°C to 105°C operating range.

Key Features

• Capacitance & Voltage: 68 µF capacitance with a 160 V rated voltage and capacitance tolerance of −20% to +20%.
• High ripple-current capability: Low-frequency ripple current 590 mA at 120 Hz and high-frequency ripple current 1.18 A at 100 kHz for demanding power filtering tasks.
• Long life at elevated temperature: Rated endurance of 10,000 hours at 105°C under specified conditions.
• Low dissipation factor: tanδ (DF) 0.20 measured at 20°C, 120 Hz, supporting efficient energy handling.
• Leakage current: Specified leakage current of 535.2 µA (measured condition per product data).
• Compact radial packaging: φ12.5 × 20 mm can with 5.0 mm lead spacing (lead spacing tolerance ±0.5 mm) in a radial, can-style package.
• Automotive-capable qualification: AEC-Q200 rating indicated in the product specifications and UCY series documentation.
• Compliance & packaging: RoHS compliant and available in bulk (no terminal forming) or bag packing; product status: mass production.
• Frequency ripple scaling: Series frequency coefficients available (50 Hz: 0.80; 120 Hz: 1.00; 1 kHz: 1.60; 10 kHz: 1.80; ≥100 kHz: 2.00) to estimate ripple performance across frequency.

Typical Applications

• Automotive power electronics: Bulk and decoupling capacitance in vehicle power modules and control units, leveraging AEC-Q200 qualification and high ripple capability.
• Power supplies and converters: Smoothing and energy storage in DC power supplies, where the 160 V rating and high ripple currents support stable output under load.
• Ballasts and industrial lighting: Filtering and ripple management in ballast circuits, taking advantage of the component’s long life at 105°C.

Unique Advantages

• High ripple handling: Measurable ripple currents of 590 mA (120 Hz) and 1.18 A (100 kHz) help reduce heating and extend system reliability in power-filtering applications.
• Long elevated-temperature life: Endurance rated at 10,000 hours at 105°C supports extended field life in high-temperature environments.
• Automotive suitability: AEC-Q200 qualification in the product data supports use in automotive-grade designs where that qualification is required.
• Compact radial form factor: φ12.5 × 20 mm can with 5 mm lead spacing provides a small footprint for space-constrained PCBs while maintaining robust radial-lead mounting.
• Predictable loss characteristics: tanδ = 0.20 at 120 Hz and 20°C provides a clear basis for thermal and dissipation planning in design.
• Regulatory compliance: RoHS compliant for global regulatory alignment in assembled products.
