• High Ripple Capability — Rated low-frequency ripple current of 1.17 A at 120 Hz and high-frequency ripple current of 1.56 A at 10 kHz to handle AC ripple in power circuits.
• Leakage Current — Leakage current specified at 390 µA, consistent with reliable standby and charged-state performance.
• Long Life, High Reliability — Endurance specified at 10,000 hours at 105 °C, reflecting the UHE series’ focus on long-term stability under DC bias plus rated ripple current.
• Compact Radial-Lead Form — φ18 × 25L can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assemblies and hand or machine insertion workflows.
• Packaging & Production Status — Available in bulk (no terminal forming) or bag packing; product is in mass production.
• Regulatory Compliance — RoHS compliant as declared in the product data.

Typical Applications

• Power supply filtering — Use as bulk or smoothing capacitance in DC power supplies where 100 V rating and 390 µF capacity reduce ripple and stabilize rails.
• Industrial control electronics — Suitable for control and power modules that require durable operation across −40 °C to 105 °C and extended endurance at elevated temperature.
• Energy-storage for backup circuits — Acts as local energy reservoir for systems requiring short-term energy delivery and ride-through capability.
• General-purpose circuit designs — A reliable choice for designers seeking a compact, high-voltage electrolytic for a variety of general-purpose applications.

Unique Advantages

• High voltage capability: 100 V rating enables use in higher-voltage rails without moving to physically larger parts.
• Low impedance performance: 210 mΩ impedance supports effective ripple suppression and lower voltage drop under load.
• Extended high-temperature endurance: 10,000-hour rating at 105 °C delivers predictable lifetime in thermally demanding environments.
• Wide operating temperature range: −40 °C to 105 °C supports deployment across varied environmental conditions.
• Compact radial package: φ18 × 25L can and 7.5 mm lead spacing provide a space-efficient through-hole solution for hand- or machine-assembled boards.
• High ripple-handling: Specified ripple currents at low and high frequencies accommodate both mains-frequency and switching-power applications.
