• High Ripple Current Capability — Low-frequency ripple current 16.4 A (120 Hz) and high-frequency ripple current 22.96 A (100 kHz) to support heavy AC and switching loads.
• Long Endurance — Load life rated at 5000 hours at 85°C under rated ripple and DC bias conditions.
• Wide Operating Temperature — Specified for −40°C to +85°C operation to cover a broad range of industrial environments.
• Low Dissipation and Leakage — Tangent of loss angle (tan δ) 0.2 (measured at 20°C, 120 Hz) and leakage current listed as 3840 µA.
• Screw Terminal Radial Can Package — Screw terminals provide secure, low-resistance power connections; package listed as φ63.5 × 100L with dimensions L: 10 × D: 6.35 cm.
• Compliance & Availability — RoHS compliant and in mass production; packaged in cardboard for shipment.

Typical Applications

• Industrial Power Supplies & Inverters — Bulk and DC-link smoothing in inverter circuitry and industrial power supply designs.
• AC Servomotor Regenerative Circuits — Suited for high-frequency regenerative voltage handling in servomotor drives and similar systems.
• High-Speed Charge–Discharge Systems — Designed to cope with the loading of high-speed charge–discharge cycles in power-electronics environments.
• General-Purpose Power Electronics — Use where high capacitance, elevated voltage rating and robust terminal connections are required.

Unique Advantages

• High ripple-current handling: Rated ripple currents (16.4 A @120 Hz, 22.96 A @100 kHz) enable reliable performance under heavy AC and switching loads.
• Extended operational life: 5000-hour load-life rating at 85°C provides predictable long-term behavior in continuous-duty applications.
• Smaller size for comparable performance: Part of the LNC family noted for smaller physical size while maintaining high ripple capability, allowing more compact power assemblies.
• Secure screw-terminal connections: Screw terminals simplify installation and deliver robust electrical contact for high-current connections.
• Measured electrical stability: Low tan δ (0.2 at 20°C, 120 Hz) and specified leakage current provide quantifiable loss and leakage characteristics for design verification.
• Regulatory readiness and supply: RoHS compliance and mass-production status support procurement and regulatory requirements.
