• High Ripple Capability Rated ripple current of 1.36 A at 105°C/100 kHz and 680 mA at 120 Hz, enabling robust AC load handling in power and ballast applications.
• Long Operational Life Rated load life of 12000 hours at 105°C, designed to maintain capacitance and leakage characteristics after extended high-temperature operation.
• Loss and Leakage Characteristics Tangent of loss angle (tan δ) specified at 0.15 and a measured leakage current value of 1060 µA, providing predictable dissipation and leakage behavior.
• Compact Through-Hole Package Radial, can-style package with 7.5 mm lead spacing and physical dimensions L: 2.5 × D: 1.8 cm for easy placement in through-hole PCB power sections.
• Operating Range Specified to operate from –25°C to +105°C, supporting high-temperature environments common in power electronics.
• RoHS Compliant Conforms to the RoHS directive as indicated in the product data.

Typical Applications

• Power Supplies Bulk filtering and high-voltage smoothing where high ripple current handling and long life are required.
• Ballast Circuits Designed for ballast applications that demand sustained ripple tolerance and reliable high-voltage performance.
• Through-Hole PCB Power Sections Radial-lead, can package suits through-hole assemblies and manual or automated insertion processes in power modules and converters.
• General-Purpose High-Voltage Circuits Useful wherever a polarized, high-voltage electrolytic capacitor with extended endurance is needed.

Unique Advantages

• High ripple-current capability: The 1.36 A (105°C/100 kHz) rating supports demanding AC loading scenarios and reduces the need for oversized capacitors.
• Extended high-temperature life: 12000-hour endurance at 105°C provides predictable long-term performance in elevated-temperature installations.
• Compact footprint for high-voltage parts: Small radial-can dimensions (L: 2.5 × D: 1.8 cm) allow designers to save board space while maintaining a 160 V rating.
• Through-hole mounting ease: Radial lead construction with 7.5 mm lead spacing simplifies placement in through-hole power assemblies.
• Clear electrical parameters: Specified tan δ (0.15) and leakage current (1060 µA) enable straightforward thermal and leakage budgeting in designs.
• Regulatory compliance: RoHS compliance supports use in environments requiring restricted-substance adherence.
