The LNC2G472MTEH is a screw-terminal, stud-bolt mount aluminum electrolytic capacitor delivering 4.7 mF (4700 µF) at 400 V in a compact can package. It combines high ripple-current capability with a reduced footprint for use where robust energy handling and secure mechanical mounting are required.

Designed for industrial power electronics, this capacitor is suited to inverter circuitry, regenerative AC servomotor systems and other high-frequency power applications that demand long load life and reliable charge–discharge performance.

Key Features

• Electrical Performance — Rated capacitance 4700 µF (4.7 mF) at 400 V with capacitance tolerance ±20% and polarization for DC and pulsed applications.
• High Ripple-Current Capability — Supports 18.3 A at 120 Hz (low frequency) and 25.62 A at 100 kHz (high frequency), enabling robust handling of continuous and high-frequency ripple currents.
• Reliability & Long Life — Load life specified at 5000 hours at 85°C under rated ripple current; endurance characteristics include charge–discharge testing (50 million cycles at ΔV = 0.3 × rated voltage).
• Leakage and Loss Characteristics — Specified leakage current of 4.11 mA and loss tangent (tan δ) of 0.2 (measurement conditions as provided), supporting predictable behavior in bias conditions.
• Thermal & Environmental — Operating temperature range −40°C to +85°C and RoHS compliance for environmental compatibility.
• Mechanical & Mounting — Screw terminals on a stud-bolt mount provide secure high-current connections; compact dimensions φ76.2 × 90 mm (L: 9 cm × D: 7.62 cm) for space-conscious power assemblies.
• Low-Temperature Stability — Impedance stability characterized down to −40°C (Z(−40°C)/Z(+20°C) specified in series data), supporting operation in cold environments.

Typical Applications

• Industrial Inverters and Motor Drives — Energy smoothing and DC link support for inverter circuitry and motor control systems, where high ripple-current capability and secure mounting are essential.
• Regenerative AC Servo Systems — Handles high-frequency regenerative voltages and fast charge–discharge cycles typical of AC servomotor regenerating energy back to the bus.
• High-Frequency Power Supplies — Bulk and ripple filtering in industrial power supplies and converters operating across a wide frequency range.
• Pulsed Power / Charge–Discharge Systems — Suited to applications that require reliable repeated charge–discharge endurance and high instantaneous current delivery.

Unique Advantages
