• Leakage Current — Specified leakage current of 2268 µA; general datasheet formula for leakage current limit is 0.03CV (µA) after 1 minute at 20°C.
• Long Endurance — Rated for 5000 hours at 105°C (with specified performance retention for capacitance, tanδ, and leakage current after endurance testing).
• Wide Temperature Range — Operating range from −55°C to +105°C for use across varied environmental conditions.
• Radial Lead Package — Can-style radial package with dimensions φ18 × 40 mm, lead spacing 7.5 mm (±0.5 mm), and bulk/bag packing options for production handling.
• RoHS Compliant — Conforms to RoHS requirements as noted in the product documentation.

Typical Applications

• Switching Power Supplies — Low-impedance performance and high ripple current capability make it suitable for output filtering and bulk smoothing in switch-mode power supplies.
• General Power Filtering — Use for bulk decoupling and energy storage on DC rails in general-purpose electronic equipment where long-term stability at elevated temperature is required.
• Industrial Power Modules — Endurance at 105°C and robust ripple handling support power conversion modules and industrial power supplies operating under thermal stress.

Unique Advantages

• Proven Endurance: 5000 hours at 105°C ensures retention of capacitance and controlled tanδ and leakage current after extended high-temperature operation.
• Dual-Frequency Ripple Handling: Rated ripple currents specified at both 120 Hz and 200 kHz provide quantifiable performance for low- and high-frequency filtering.
• Compact Radial Can: φ18 × 40 mm form factor with 7.5 mm lead spacing offers a compact solution for through-hole placement while maintaining substantial capacitance.
• Clear Electrical Specs: Measured tanδ (0.08 at 20°C/120 Hz/63 V) and specified leakage current allow straightforward thermal and reliability calculations for power designs.
• Production-Ready Packaging: Available in bulk and bag packing to support prototype through high-volume assembly workflows.
• RoHS Compliance: Meets RoHS directive requirements, simplifying environmental compliance for final products.
