Key Features

• Electrical Capacity — 1.8 mF rated capacitance with ±20% tolerance at 120 Hz, 20°C, and polarized construction suitable for DC power applications.
• High Voltage Rating — 450 V rated voltage for use in inverter and high-voltage power-supply sections.
• High Ripple Current — Designed for elevated ripple; specified at 11.5 A (120 Hz) and 16.1 A (100 kHz), supporting high-frequency and high-current ripple environments.
• Extended Endurance — Load-life specification of 5000 hours at 85°C under rated ripple current and DC bias, with defined limits for capacitance, tan δ, and leakage current after test.
• Charge–Discharge Robustness — Qualified for 50 million charge–discharge cycles (ΔV = rated voltage × 0.3, 3 Hz) at room temperature while meeting post-test electrical limits.
• Temperature Range — Operates from –40°C to +85°C, allowing use across a broad industrial temperature span.
• Compact Screw-Terminal Can — Radial can with screw terminals for secure electrical and mechanical connections in power assemblies; smaller-sized design within the LNC series.
• RoHS Compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Bulk and filtering capacitor for inverter power stages where high DC voltage and ripple endurance are required.
• AC Servomotor Regeneration — Energy buffering and smoothing for high-frequency regenerative voltages in servo drives and motor controllers.
• High-Speed Charge–Discharge Systems — Applications that require frequent or rapid charge–discharge cycles, supported by validated endurance testing.
• Power Supply Filters — Filter and smoothing duties in industrial power supplies handling elevated ripple currents at both low and high frequencies.

Unique Advantages

• High Ripple Handling: Specified ripple currents of 11.5 A (120 Hz) and 16.1 A (100 kHz) enable reliable operation in high-frequency and high-current environments.
• Long Operating Life: 5000-hour load-life at 85°C under rated ripple current provides predictable lifetime behavior for industrial deployments.
• Charge–Discharge Durability: Validated for 50 million charge–discharge cycles, demonstrating robustness for frequent energy cycling applications.
• Screw-Terminal Mounting: Provides secure, serviceable connections well suited to industrial assemblies and power modules.
• Compact Series Design: Part of a smaller-sized, higher-ripple-current family (LNC), offering space-efficient solutions where LNX/LNK options may be larger.
• Regulatory Compliance: RoHS conformity supports use in regions requiring restricted substance compliance.
