Key Features

• Electrical — 4.7 mF at 500 V: Rated capacitance 4.7 mF (4700 µF) with a rated voltage of 500 V; the LNU series supports rated voltages in the 400–525 V range.
• High ripple‑current handling: Rated ripple current of 13.9 A at 120 Hz and 19.46 A at 10 kHz, enabling effective smoothing and energy buffering in high‑frequency power circuits.
• Temperature and life characteristics: Operating temperature range –40 °C to +105 °C with a load life of 5000 hours at 105 °C under rated ripple current conditions.
• Charge–discharge endurance: Endurance verified for 50 million charge–discharge cycles (3 Hz), supporting designs that require frequent energy cycling.
• Mechanical — Screw terminal, radial can: Screw terminal mounting for secure high‑current connections; package dimensions L: 16.5 × D: 7.62 cm and nominal bolt size M5 for applicable diameters as specified in the series drawing.
• Insulation and voltage proof: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; no abnormality under AC 2500 V for 1 minute between terminal and bracket.
• Leakage current specification: After 5 minutes’ application of rated voltage, leakage current is specified as not more than 3√(C·V) µA or 5 mA, whichever is smaller.
• RoHS compliant: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies (inverter circuitry): Energy storage and smoothing on high‑voltage DC rails for inverter front‑ends and power conversion.
• AC servomotor regenerative systems: Handles high‑frequency regenerative voltages and supports energy recapture in motor drives.
• General inverters: Supports high‑speed charge–discharge loading typical of inverter topologies and power conversion stages.
• High‑frequency power systems: Provides stable capacitance and ripple absorption in systems operating across 120 Hz to multi‑kHz ranges.

Unique Advantages

• High‑voltage in a compact package: Delivers 500 V rated performance (series rated up to 525 V) in a smaller size compared with the referenced LNT series, enabling tighter power‑rail layouts.
• Designed for heavy ripple environments: High ripple current ratings at both 120 Hz and 10 kHz reduce heating and improve reliability in demanding power applications.
• Extended high‑temperature life: 5000‑hour load life at 105 °C under ripple current maintains capacitance, tan δ, and leakage within specified limits for sustained operation.
• Robust cycling durability: Validated for 50 million charge–discharge cycles, supporting applications with frequent energy transfer and regenerative events.
• Secure, serviceable connections: Screw terminal construction and M5‑nominal bolt interface facilitate reliable high‑current connections and easier field serviceability.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements for modern industrial equipment.
