• Controlled Dissipation Factor — tan δ of 0.16 measured at 20°C and 120 Hz for predictable loss characteristics.
• Wide Temperature & Long Life — Operating range from −55°C to +105°C with an endurance rating of 8000 hours at 105°C.
• Package & Mounting — Radial lead, polarized can, physical size φ18 × 35.5 mm with 7.5 mm lead spacing (±0.5 mm tolerance) for through-hole PCB designs.
• Reliability Rating — UPW series engineered as a high-reliability type; this part carries an AEC-Q200 rating for automotive applications.
• Leakage Current — Specified leakage current of 3465 µA after application of rated voltage.
• Production & Packaging — Mass production status with bulk (no terminal forming) and bag packing options for volume assembly handling.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output decoupling where high ripple-current endurance and low impedance are required.
• Automotive Electronic Systems — Energy storage and decoupling in automotive power modules and electronics (AEC-Q200 rated).
• Power Management Modules — DC bus stabilization and transient suppression in DC–DC converters and power distribution circuits.

Unique Advantages

• High ripple handling: Rated ripple currents of 3.128 A (120 Hz) and 3.68 A (10 kHz) support robust operation under switching loads.
• Low impedance: 30 mΩ impedance helps minimize voltage drop and heat generation at high current, improving overall power-stage efficiency.
• Long operational life: 8000 hours at 105°C provides extended service life in elevated-temperature environments.
• AEC-Q200 qualified: Enables use in automotive electronic designs that require recognized component-level reliability.
• Compact, through-hole form factor: φ18 × 35.5 mm radial can and 7.5 mm lead spacing simplify board layout for high-current through-hole power designs.
• Series frequency behavior: UPW series frequency coefficients provide predictable ripple performance from 50 Hz up to 10 kHz and above for large capacitances.
