• Package & Mounting — Radial lead (can) package, size φ18 × 25 mm (L: 2.5 × D: 1.8 cm) with 7.5 mm lead spacing (±0.5 mm tolerance) for through-hole assembly.
• High Ripple Current — Rated ripple performance of 437.5 mA at 120 Hz and 875 mA at 100 kHz, supporting AC ripple handling across common power frequencies.
• Long Life Endurance — Designed for 12,000 hours of operation at +105 °C under rated conditions, providing extended service life in demanding thermal environments.
• Thermal Range — Operating temperature from −25 °C to +105 °C for use across a wide range of ambient conditions.
• Electrical Loss & Leakage — Maximum tan δ of 0.20 at 20 °C, 120 Hz (350 V rating); specified leakage current listed as 1,052 µA after 1 minute at 20 °C.
• Polarized with Standard Tolerance — Polarized device with capacitance tolerance of ±20% (−20% to +20%).
• Regulatory — RoHS compliant.

Typical Applications

• Power Supplies — Bulk filtering and ripple suppression in switch-mode and linear power supply outputs where 350 V rating and high ripple capability are required.
• Ballast and Lamp Drivers — Energy storage and smoothing in ballast circuits, leveraging the UCA series' stated suitability for ballast applications.
• Industrial Power Electronics — DC link, snubber, and decoupling roles in industrial converters and inverters that operate within the −25 °C to +105 °C range.
• General-Purpose Filtering — Through-hole designs requiring a compact, high-voltage polarized capacitor for general purpose power conditioning.

Unique Advantages

• High ripple capability: Specified ripple currents of 437.5 mA (120 Hz) and 875 mA (100 kHz) allow handling of significant AC stress without immediate degradation.
• Extended load-life: 12,000-hour endurance at 105 °C provides predictable lifetime performance for long-term deployments.
• Compact radial form factor: φ18 × 25 mm can with 7.5 mm lead spacing delivers a space-efficient through-hole solution for power boards.
• Wide operating temperature: −25 °C to +105 °C supports use in varied ambient environments.
• Measurable electrical characteristics: Known tan δ (≤0.20 at 350 V, 120 Hz) and specified leakage current (1,052 µA) enable straightforward design margining and system-level calculations.
• RoHS compliant: Meets current RoHS requirements for regulatory alignment in assemblies.
