• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) 0.2 (measured at 20°C, 120 Hz) and leakage current specified at 2800 µA.
• Endurance and Temperature Range — Rated life of 2000 hours at 105°C; operating temperature range −40°C to +105°C.
• Compact Radial-Lead Package — Can-style radial package, case size φ18 × 40 mm with 7.5 mm lead spacing (±0.5 mm), ideal for through-hole assemblies.
• Packaging Options — Available in Bulk (no terminal forming) and Bag packing to suit assembly and stocking preferences.
• RoHS Compliant — Conforms to RoHS requirements.

Typical Applications

• Ballasts — Specifically noted as suited for ballast applications where high-voltage, high-ripple components are required.
• General-purpose Power Circuits — Used in a wide range of general-purpose high-voltage power circuits that require a compact electrolytic capacitor with solid ripple performance.
• Industrial Equipment — Fits compact, high-voltage stages in industrial control and power electronics where endurance at elevated temperature matters.

Unique Advantages

• High-voltage capability in a small footprint — 450 V rating in a φ18 × 40 mm can provides a space-efficient option for high-voltage designs.
• Robust ripple handling across frequencies — Specified ripple currents of 970 mA (120 Hz) and 1.455 A (10 kHz) support demanding AC loading conditions.
• Long high-temperature endurance — 2000 hours rated life at 105°C helps ensure predictable performance in thermally harsh environments.
• Predictable electrical behavior — Clear specifications for tan δ (0.2 at 20°C/120 Hz) and leakage current (2800 µA) simplify margining and reliability analysis.
• Through-hole, serviceable form factor — Radial lead configuration and standard lead spacing ease prototyping, repair, and manual assembly.
• Regulatory compliance — RoHS compliance for restricted substances.
