• High Ripple Capability: Low-frequency ripple current of 3.376 A at 120 Hz and high-frequency ripple current of 4.22 A at 10 kHz for demanding ripple environments.
• Long Endurance: Rated for 10,000 hours at 105°C under specified endurance test conditions, providing prolonged operational lifetime.
• Wide Operating Temperature: Specified to operate from -40°C to +105°C, suitable for varied thermal environments.
• Leakage and Dissipation: Leakage current specified at 1175 µA; tan δ (DF) = 0.2 measured at 20°C, 120 Hz, enabling predictable loss characteristics.
• Form Factor & Mounting: Radial lead, polarized aluminum-can package with lead spacing 7.5 mm and overall dimensions φ18 × 35.5 mm for through-hole assemblies.
• Compliance: RoHS-compliant construction.

Typical Applications

• General-Purpose Power Filtering: Bulk capacitance and low impedance make it suitable for smoothing and filtering in power supply circuits and converters.
• Decoupling and Energy Storage: High capacitance supports energy buffering and decoupling on power rails in consumer and industrial electronics.
• High-Ripple Environments: Elevated ripple current ratings enable use where sustained AC ripple is present at both low and high frequencies.

Unique Advantages

• Long-Life Reliability: 10,000-hour endurance at 105°C provides extended service life under high-temperature stress.
• High Ripple Handling: Distinct LF and HF ripple current ratings (3.376 A @120 Hz, 4.22 A @10 kHz) reduce thermal stress and improve stability in high-ripple circuits.
• Compact, Through-Hole Form Factor: φ18 × 35.5 mm radial-can package offers a balance of capacitance density and ease of PCB mounting for through-hole designs.
• Predictable Electrical Losses: Specified tan δ and leakage current enable reliable dissipation budgeting and thermal design.
• Wide Temperature Range: Operation from -40°C to +105°C supports deployment across diverse ambient conditions.
• Regulatory Compliance: RoHS status ensures suitability for designs requiring restricted-substance compliance.
