UCY2C681MHD

The UCY2C681MHD is a high-reliability, miniature aluminum electrolytic capacitor in Nichicon’s UCY series. It is a radial-lead, polarized device rated at 680 µF and 160 V, designed for applications that demand sustained ripple handling and long operational life at elevated temperatures.

Targeted use cases include power supplies, ballast circuits and automotive electronic systems. Key value propositions are its high ripple-current capability, long endurance at 105°C, and AEC-Q200 qualification for demanding environments.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 160 V and capacitance tolerance of −20% to +20%.
• High Ripple Current — Supports 2.3 A low-frequency ripple current at 120 Hz and 4.6 A high-frequency ripple current at 100 kHz, enabling robust filtering in power stages.
• Low Dissipation Factor — tanδ (DF) 0.20 maximum measured at 20°C, 120 Hz, for controlled losses in AC conditions.
• Leakage Current — Typical leakage current specification of 4,452 µA (measured condition per product data), useful for budgeting standby losses.
• Long Endurance — Rated life of 12,000 hours at +105°C under rated voltage and ripple conditions for extended service life.
• Operating Temperature — Specified for −40°C to +105°C operation to cover a wide range of environmental conditions.
• Package & Mechanical — Radial can package, size φ18 × 46 mm (L:4.6 × D:1.8 cm), lead spacing 7.5 mm ±0.5 mm, radial lead mounting.
• Industry Qualification & Compliance — AEC-Q200 qualified and RoHS compliant, suitable for regulated and automotive-related designs.
• Production & Packaging — Available in bulk (no terminal forming) / bag packing and listed as mass production.

Typical Applications

• Power Supplies — Bulk energy storage and smoothing for DC power rails where high ripple current capability improves regulator stability.
• Ballasts — Filtering and energy buffering in ballast circuits that require robust ripple handling and long life at elevated temperatures.
• Automotive Electronic Systems — Energy storage and filtering in automotive electronics, supported by AEC-Q200 qualification and a −40°C to +105°C operating range.

Unique Advantages

• High ripple-current tolerance: Enables smaller, more efficient filtering stages by handling 2.3 A at 120 Hz and 4.6 A at 100 kHz.
• Extended high-temperature life: 12,000-hour endurance at 105°C reduces maintenance and replacement frequency in thermal-stressed designs.
• Automotive-capable qualification: AEC-Q200 qualification provides confidence for use in vehicle electronics and related high-reliability applications.
• Compact radial-can form factor: φ18 × 46 mm dimensions and standard 7.5 mm lead spacing simplify PCB layout for through-hole and power module designs.
• Verified electrical characteristics: Defined tanδ, leakage, and tolerance figures allow accurate system-level loss, leakage and tolerance budgeting.
• Regulatory compliance: RoHS compliance supports use in regulated markets and facilitates global deployment.
