UCS2V101MHD

The UCS2V101MHD is a miniature, radial-lead aluminum electrolytic capacitor in Nichicon's UCS series designed for high ripple current and long-term reliability. Its radial can package and polarized construction make it suitable for through-hole power applications that require compact, high-voltage bulk capacitance.

Engineered for demanding environments, this capacitor is specified for operation from –40°C to +105°C with a rated life up to 10,000 hours at +105°C, making it appropriate for power supplies, ballast circuits and general-purpose high-ripple applications. The part is RoHS compliant (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Rated Voltage — 100 µF nominal capacitance with a 350 V rating for high-voltage DC applications.
• High Ripple Current — Rated ripple performance includes 787.5 mA at 120 Hz and 1.575 A at 100 kHz (measured at 105°C for the 100 kHz value), supporting heavy AC superposition on DC rails.
• Extended High-Temperature Life — Endurance specified up to 10,000 hours at +105°C under rated conditions, supporting long service intervals in hot operating environments.
• Wide Operating Temperature — Specified for −40°C to +105°C operation for broad environmental tolerance.
• Low Leakage Current — Leakage limited to 0.04CV + 100 µA after 1 minute’s application of rated voltage at 20°C, enabling predictable bias behavior in designs.
• Compact Radial Can Package — Radial lead construction with 7.5 mm lead spacing and a compact case (approximately 2.5 × 1.8 cm), suitable for through-hole assembly and dense layouts.
• Polarized with ±20% Tolerance — Standard electrolytic polarity and ±20% capacitance tolerance at 120 Hz, 20°C.
• RoHS Compliant — Conforms to RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies — Bulk smoothing and energy storage on high-voltage DC rails where high ripple capability and long life are needed.
• Ballasts and Lighting — Specified for ballast applications requiring reliable high-voltage capacitors that tolerate continuous ripple current.
• Industrial Power Modules — General-purpose use in industrial power circuitry and converters that encounter elevated temperatures and ripple stresses.

Unique Advantages

• High ripple tolerance: Measured ripple ratings (787.5 mA at 120 Hz and 1.575 A at 100 kHz) enable operation in circuits with significant AC components on DC rails.
• Long life at elevated temperature: 10,000-hour rating at +105°C reduces frequency of capacitor replacement in high-temperature installations.
• High-voltage capability: 350 V rating supports higher-voltage designs without series stacking.
• Predictable leakage behavior: Leakage defined by 0.04CV + 100 µA after 1 minute at 20°C helps with bias planning and margin analysis.
• Compact through-hole package: Radial can and 7.5 mm lead spacing simplify PCB layout and assembly for through-hole designs.
• RoHS compliance: Meets applicable RoHS directives for environmental and regulatory compatibility.
