LNC2H102MSEF

The LNC2H102MSEF is a screw-terminal aluminum electrolytic capacitor rated at 1000 µF and 500 V, optimized for industrial power electronics. It is a smaller-sized, high-ripple-current design intended for inverter circuitry, high-frequency regenerative voltages and other demanding power-supply applications.

Designed for continuous operation up to 85°C with a rated load life of 5000 hours under applied ripple current, this capacitor balances compact packaging with high ripple-handling and charge–discharge endurance for robust inverter and servo systems.

Key Features

• Electrical characteristics — 1000 µF capacitance with ±20% tolerance and 500 V rated voltage; polarized design for DC power applications.
• High ripple capability — Specified ripple current of 10.3 A at 120 Hz and 14.42 A at 100 kHz, enabling reliable smoothing under heavy AC ripple and high-frequency regenerative voltages.
• Thermal and lifecycle performance — Rated for operation from −40°C to +85°C with a load-life specification of 5000 hours at 85°C when subjected to rated ripple current and DC bias.
• Endurance and charge–discharge robustness — Meets series-level endurance criteria including 50 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz) and retention of electrical characteristics after long-term ripple application.
• Leakage and insulation — Leakage current after 5 minutes at rated voltage is limited to not more than 3√(V) µA or 5 mA (whichever is smaller) at 20°C; insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket.
• Compact screw-terminal package — Radial can with screw terminals and three-leg bracket options, sized L: 8.5 × D: 5.1 cm to simplify mounting in power modules.
• Low-temperature stability — Impedance ratio Z(−40°C)/Z(+20°C) ≤ 8, supporting performance in cold-start or low-temperature environments.
• RoHS compliance — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverters — Bulk and DC-link smoothing for general inverters where high ripple current and long life are required.
• AC servomotor drives — Handling high-frequency regenerative voltages and rapid charge–discharge cycles in motor control systems.
• Power supplies for industrial equipment — Energy storage and ripple suppression in DC power supplies used in factory automation and drive systems.

Unique Advantages

• Smaller footprint with high ripple capability — Delivers higher ripple current in a reduced package compared to earlier series, enabling space-efficient power module designs.
• Long operational life under ripple stress — 5000-hour load-life rating at 85°C with applied ripple current provides predictable aging for maintenance planning.
• Designed for high-speed cycling — Qualified for extensive charge–discharge cycling (50 million cycles), useful in regenerative and fast-switching applications.
• Measured low-temperature behavior — Maintains usable impedance characteristics down to −40°C, supporting wide ambient ranges.
• Robust leakage and insulation limits — Tight leakage current and insulation resistance specifications aid in stable system behavior and safety margins.
• Regulatory compliance — RoHS compliance simplifies integration into regionally regulated equipment.
