• Ripple Current Handling Low-frequency ripple current of 605.5 mA at 120 Hz and high-frequency ripple current of 865 mA at 10 kHz, enabling reliable smoothing across common power and switching frequencies.
• Loss Characteristics Dissipation factor (tan δ) of 0.12 measured at 20°C, 120 Hz, providing a quantified measure of energy loss for thermal and circuit design considerations.
• Reliability & Lifetime Long-life endurance: 7000 hours at 105°C under rated conditions as specified for the UHE series, supporting extended operational periods at elevated temperatures.
• Temperature Range Operating from −40°C to +105°C to accommodate a wide range of environmental conditions.
• Compact Radial Package Size φ10 × 12.5 mm (D × L) with 5.0 mm lead spacing and radial lead mounting for through-hole PCB assembly; available in bulk or bag packing.
• Leakage Current Specified leakage current of 77 µA, supporting predictable standby and low-current performance.
• RoHS Compliant Conforms to RoHS requirements as indicated for the series.

Typical Applications

• Power Supply Smoothing — Use for bulk smoothing and reservoir functions in DC power supplies, leveraging 220 µF capacitance and 35 V rating to reduce voltage ripple.
• Decoupling and Bulk Energy Storage — Serves as local energy storage for transient loads where compact size and 605.5 mA–865 mA ripple capability are required.
• Switching Regulator Filtering — Suitable for filtering at both low and high switching frequencies, supported by specified ripple currents at 120 Hz and 10 kHz and a low impedance of 320 mΩ.

Unique Advantages

• Measured Low Impedance — 320 mΩ impedance helps minimize voltage drop under load and improve filtering effectiveness in power rails.
• High Ripple Capability Across Frequencies — Explicit ripple current specifications at 120 Hz and 10 kHz provide predictable performance for both line-frequency and switching applications.
• Proven Long Endurance — Rated for 7000 hours at 105°C per UHE series endurance criteria, aiding designs that require sustained operation at elevated temperatures.
• Compact Through-Hole Form Factor — φ10 × 12.5 mm can with 5.0 mm lead spacing delivers a small footprint for space-constrained boards while retaining radial-lead robustness.
• Quantified Leakage and Loss Metrics — Specified leakage current (77 µA) and tan δ (0.12) support precise thermal and power-loss budgeting in designs.
• Regulatory Compliance — RoHS-compliant construction aligns with modern assembly and environmental requirements.
