LNC2W272MSEG

The LNC2W272MSEG is a Nichicon LNC-series aluminum electrolytic capacitor in a screw-terminal, radial can package. It provides 2.7 mF (2700 µF) capacitance at a 450 V rating with polarized screw-terminals designed for industrial power electronics.

Engineered for inverter circuitry and high-frequency regenerative voltage in AC servomotors and general inverters, this part delivers high ripple-current capability in a smaller footprint, plus a 5000-hour load life under rated ripple at 85°C.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance with a 450 V rated voltage and ±20% capacitance tolerance (measured at 120 Hz, 20°C).
• Screw-Terminal, Polarized Package — Radial can with screw terminals for secure, high-current connections suited to industrial power assemblies.
• High Ripple‑Current Performance — Specified ripple current of 13.7 A at 120 Hz and 19.18 A at 100 kHz to support high-frequency and high-current inverter/regenerative loads.
• Temperature Range & Load Life — Rated for −40°C to +85°C operation with a specified load life of 5000 hours when ripple current is applied at 85°C.
• Charge‑Discharge Endurance — Meets endurance requirements after 50 million charge‑discharge cycles (ΔV = rated voltage × 0.3, cycle 3 Hz) at room temperature.
• Insulation and Voltage Proof — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; no abnormality at AC 2500 V for 1 minute between terminal and bracket.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is not more than 3√V (µA) or 5 mA, whichever is smaller (measured at 20°C).
• Smaller-Sized, High Ripple Capability — LNC-series design provides smaller physical size while delivering higher ripple current compared with the LNX and LNK series variants.
• RoHS Compliant — Complies with RoHS directive (2011/65/EU and (EU)2015/863).
• Marking — Product is printed with white letters on a black sleeve for clear identification.

Typical Applications

• Industrial Inverters — Bulk energy storage and smoothing in inverter circuitry where high-voltage, high-ripple performance is required.
• AC Servomotor Regenerative Circuits — Handles high-frequency regenerative voltages and rapid charge/discharge cycles in servo drives.
• Industrial Power Supplies — Filtering and energy buffering in high-voltage power supplies for industrial equipment.
• High-Speed Charge/Discharge Systems — Suited to applications that subject capacitors to frequent, rapid charge and discharge events.

Unique Advantages

• High ripple-current capacity in a reduced footprint: Rated ripple currents of 13.7 A (120 Hz) and 19.18 A (100 kHz) combined with a smaller-sized design make it easier to meet thermal and space constraints.
• Extended high-temperature load life: Designed for 5000 hours of operation with applied ripple at 85°C, supporting reliable long-term operation under stress.
• Proven charge/discharge durability: Meets post-test specifications after 50 million charge-discharge cycles, ensuring resilience in repetitive duty cycles.
• Robust insulation and voltage withstand: High insulation resistance (>100 MΩ at DC 500 V) and AC 2500 V/1 minute voltage proof between terminal and bracket enhance safety margins in high-voltage systems.
• Clear engineering specifications: Leakage current and tolerance figures are specified to aid thermal, reliability, and system-level design decisions.
• RoHS compliant material set: Meets applicable RoHS directives for regulatory and environmental requirements.
