LNC2V272MSEG

The LNC2V272MSEG is a screw-terminal aluminum electrolytic capacitor optimized for industrial power systems. It delivers 2.7 mF (2700 µF) at 350 V in a radial can with screw terminals, designed for applications requiring high ripple handling and compact packaging.

Engineered for inverter and regenerative circuits, this capacitor provides elevated ripple-current capability and a defined 5000-hour load life at 85°C, making it suitable for AC servomotor drives, general inverters and other high-frequency charge–discharge environments.

Key Features

• Capacitance & Rated Voltage — 2.7 mF (2700 µF) rated at 350 V with ±20% tolerance (at 120 Hz, 20°C).
• Screw Terminal / Radial Can Package — Screw terminal mounting for robust electrical and mechanical connection; package style listed as radial, can with screw terminals.
• High Ripple Current — Rated ripple current of 13.7 A at 120 Hz and 19.18 A at 100 kHz to support high-frequency regenerative and inverter applications.
• Operating Temperature & Lifetime — Operating range −40°C to +85°C with a load life of 5000 hours when subjected to rated ripple current at 85°C.
• Endurance & Charge–Discharge Robustness — Meets endurance requirements after DC bias plus rated ripple current for 5000 hours at 85°C; designed to withstand charge–discharge testing (50 million cycles, ΔV = rated voltage × 0.3, 3 Hz) at room temperature.
• Leakage Current — After 5 minutes’ application of rated voltage, leakage current is not more than 3√V (µA) or 5 mA, whichever is smaller (at 20°C), per datasheet specification.
• Insulation & Voltage Proof — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket without abnormality.
• Size & Mechanical — Physical dimensions: length 7.0 cm × diameter 6.35 cm; maximum seated height specified as 2.756 inch.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies — Used as bulk energy storage and smoothing capacitors in inverter front-ends where elevated ripple capability and long life are required.
• AC Servomotor Regenerative Circuits — Suited for high-frequency regenerative voltages encountered in servo drives thanks to high ripple-current rating and charge–discharge endurance.
• General Motor Drives — Employed in drive systems to handle rapid charge–discharge cycles and support stable DC bus performance.

Unique Advantages

• High ripple-current capability: Specified 13.7 A (120 Hz) and 19.18 A (100 kHz) ratings support high-frequency and regenerative loads, reducing thermal stress in demanding applications.
• Compact, screw-terminal form factor: Radial can with screw terminals provides a secure mechanical connection and a smaller footprint compared to larger series, enabling denser power assemblies.
• Proven endurance under load: Designed for 5000 hours of operation at 85°C under rated ripple conditions with defined post-test limits on capacitance, tan δ and leakage current.
• Robust electrical isolation: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V voltage proof between terminal and bracket for reliable system safety margins.
• Designed for repetitive charge–discharge: Meets charge–discharge endurance testing (50 million cycles at ΔV = 0.3 × rated voltage), making it suitable for high-speed switching environments.
• Regulatory compliance: RoHS conformity supports deployment in regulated industrial and commercial equipment.
