LNU2W272MTEG

The LNU2W272MTEG is a screw‑terminal, aluminum electrolytic capacitor designed for high‑voltage industrial power applications. It delivers 2700 µF capacitance at a 450 V rating (with a rated voltage range up to DC 525 V) in a radial can package with stud bolt mounting.

Engineered for inverter and regenerative power circuits, this capacitor supports high‑speed charge/discharge and high‑frequency regenerative voltages typical in AC servomotor drives and general inverter power supplies, while offering long life at elevated temperature.

Key Features

• Capacitance & Voltage: 2700 µF (2.7 mF) nominal capacitance with a 450 V rated voltage; rated voltage range specified up to DC 525 V.
• Temperature & Lifetime: Operating temperature range −40 °C to +105 °C with a specified load life of 5000 hours at 105 °C under rated ripple current.
• High ripple handling: Ripple current capability of 13.1 A at 120 Hz and 18.34 A at 10 kHz to support high‑frequency and high‑power switching environments.
• Mechanical & Mounting: Radial can with screw terminals and stud bolt mount for robust, low‑impedance connections in industrial assemblies; nominal dimensions L: 10 cm × D: 6.35 cm.
• Endurance & Charge‑Discharge Robustness: Meets endurance criteria after DC bias plus rated ripple for 5000 hours at 105 °C; also specified for 50 million charge–discharge cycles at 3 Hz with ΔV ≈ rated voltage ±0.3 V.
• Leakage & Insulation: Leakage current after 5 minutes at 20 °C is ≤ 3√(C·V) µA or 5 mA (whichever is smaller). Insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V applied for 1 minute shows no abnormality.
• Low‑temperature stability: Impedance ratio Z(−40 °C)/Z(+20 °C) ≤ 8 for rated voltages 400–525 V.
• RoHS compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies: Energy storage and smoothing for inverter front‑ends where high DC voltage and robust ripple handling are required.
• AC servomotor drives: Supports high‑frequency regenerative voltages and rapid charge/discharge cycles in motor control systems.
• Regenerative power circuits: Filtering and energy buffering for high‑frequency regenerative events in power conversion and drive electronics.

Unique Advantages

• High‑voltage capability in a compact package: 450 V rating with a rated range up to 525 V provides headroom for industrial DC bus applications while retaining a smaller footprint compared with earlier LNT models.
• Designed for elevated temperatures: Rated operation to 105 °C and a 5000‑hour load life under ripple current improves reliability in thermally demanding environments.
• Robust ripple and frequency performance: Specified ripple current at both 120 Hz and 10 kHz supports a wide range of switching frequencies and high‑power ripple conditions.
• Mechanical reliability: Screw‑terminal, stud bolt mounting ensures secure, low‑resistance connections suitable for industrial assemblies and repeatable serviceability.
• Endurance under cycling: Verified for long charge–discharge endurance (50 million cycles at specified test conditions), supporting repetitive dynamic load profiles.
• Tested insulation and leakage characteristics: Clear leakage current limits and insulation resistance/voltage‑proof specifications facilitate predictable integration into safety‑minded designs.
