UCS2E680MHD

The UCS2E680MHD is a miniature, radial-lead aluminum electrolytic capacitor designed for high ripple current and long-term reliability. It delivers 68 µF capacitance at a 250 V rating in a compact radial can package with 7.5 mm lead spacing.

Optimized for power supply and ballast applications, this RoHS-compliant device combines high ripple capability, extended load-life at elevated temperature, and a wide operating temperature range for demanding general-purpose power electronics.

Key Features

• Capacitance & Voltage: 68 µF capacitance rated for 250 V DC with ±20% tolerance at 120 Hz, 20°C.
• High ripple current capability: Rated ripple current of 650 mA at 120 Hz and 1.3 A at 100 kHz, supported by the UCS series frequency coefficients (0.50 at 120 Hz, 1.00 at 100 kHz or more).
• Long-life endurance: Designed to withstand load life of up to 10,000 hours at +105°C (series endurance specification: 8,000–10,000 hours at 105°C under rated conditions).
• Wide temperature range: Operating temperature from −40°C to +105°C for reliable performance across high- and low-temperature environments.
• Low-loss electrical characteristics: Tangent of loss angle (tan δ) for 250 V is specified with a maximum of 0.20 (measured at 120 Hz, 20°C).
• Leakage current spec: Leakage after 1 minute at rated voltage and 20°C is specified as not more than 0.04CV + 100 (µA), providing predictable leakage behavior for design calculations.
• Compact, radial-can package: Physical size L: 2.0 cm × D: 1.6 cm with radial lead mounting and 7.5 mm lead spacing, suitable for through-hole assemblies.
• RoHS compliant: Meets RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supplies — Bulk filtering and ripple handling in AC/DC and DC/DC power conversion where elevated ripple current capability is required.
• Ballasts and lighting drivers — Suited to applications that demand stable performance under continuous AC ripple stress at elevated temperature.
• General-purpose industrial electronics — Filtering and energy-storage roles where long life at +105°C and reliable leakage characteristics are important.

Unique Advantages

• High ripple endurance: Explicit ripple-current ratings at 120 Hz and 100 kHz let designers size capacitors confidently for both low- and high-frequency ripple environments.
• Extended operational life at high temperature: Endurance specified up to 10,000 hours at +105°C supports long-term reliability in thermally demanding systems.
• Predictable electrical behavior: Specified tan δ and leakage current formula enable accurate modeling of loss and standby leakage in system power budgets.
• Space-efficient radial can: Compact dimensions with radial leads and 7.5 mm lead spacing simplify through-hole PCB layout while conserving board area.
• Regulatory compliance: RoHS conformity supports designs targeting restricted-substance requirements.
