LNC2G122MTEF

The LNC2G122MTEF is a screw‑terminal aluminum electrolytic capacitor designed for industrial power electronics. As a stud‑mount, radial can capacitor, it delivers 1200 µF at a 400 V rating and is optimized for inverter and regenerative power circuits.

This part emphasizes a compact footprint with elevated ripple capability and is specified for continuous operation from −40 °C to +85 °C with a rated load life of 5000 hours at 85 °C under rated ripple current conditions.

Key Features

• Capacitance and Voltage — 1200 µF nominal capacitance at a 400 V rated DC voltage, ±20% tolerance at 120 Hz, 20 °C.
• Screw‑terminal / Stud Mount — Radial can with screw terminals and stud bolt mounting for secure mechanical and electrical connections in power assemblies.
• High ripple current capability — Rated ripple current: 9.3 A at 120 Hz and 13.02 A at 100 kHz, suitable for high‑frequency and pulsed load environments.
• Elevated temperature endurance — Load life: 5000 hours at 85 °C with D.C. bias plus rated ripple current; capacitance change, tan δ and leakage current limits specified for end‑of‑life verification.
• Wide operating temperature — Specified for −40 °C to +85 °C operation.
• High reliability electrical characteristics — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; voltage proof of AC 2500 V for 1 minute between terminal and bracket.
• Charge‑discharge endurance — Designed to withstand charge/discharge cycling; datasheet specifies verification after 50 million cycles (ΔV = rated × 0.3, 3 Hz) at room temperature.
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Leakage current specification — After 5 minutes at rated voltage, leakage current is ≤ 3√(V) µA or 5 mA, whichever is smaller (at 20 °C).

Typical Applications

• Industrial inverter power supplies — Bulk DC link and smoothing for inverter circuitry where high ripple handling and long life at 85 °C are required.
• AC servomotor regenerative circuits — Energy capture and smoothing in high‑frequency regenerative voltage environments.
• High‑speed charge/discharge systems — Applications that subject capacitors to rapid charge/discharge cycles benefit from the specified endurance testing.
• General industrial power electronics — DC bus filtering and transient energy buffering in factory automation and power conversion equipment.

Unique Advantages

• Compact, high‑ripple design — Smaller size with higher ripple current capability compared to earlier LNC series variants, enabling denser power module layouts.
• Proven elevated‑temperature life — 5000 hours at 85 °C under rated ripple conditions provides predictable end‑of‑life behavior for industrial designs.
• High‑frequency performance — Ripple current rating at 100 kHz (13.02 A) supports high‑frequency switching and regenerative circuits.
• Robust electrical integrity — High insulation resistance and AC voltage proof between terminal and bracket increase design confidence for high‑voltage installations.
• Mechanically secure mounting — Stud bolt mount and screw terminals offer reliable electrical and mechanical connections for heavy‑duty power assemblies.
• Regulatory compliance — RoHS conformity supports restricted‑substance requirements for industrial equipment.
