LNC2H332MTEH

The LNC2H332MTEH from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNC series, rated 3.3 mF (3300 µF) at 500 V. It is a stud/bolt‑mount radial can designed for industrial power electronics where high ripple handling, compact size, and robust charge–discharge performance are required.

Engineered for inverter circuitry and high‑frequency regenerative voltage applications such as AC servomotor drives and general inverters, this part offers a combination of high ripple current capability, long load life at elevated temperature, and RoHS compliance.

Key Features

• Capacitance & Rated Voltage: 3.3 mF (3300 µF) nominal capacitance at a rated voltage of 500 V—useful for DC link, smoothing, and energy buffer applications in power electronics.
• High ripple‑current capability: Rated ripple current of 17.8 A at 120 Hz and 24.92 A at 100 kHz, enabling sustained operation under heavy AC ripple conditions and high‑frequency regeneration.
• Compact screw‑terminal package: Radial can with screw terminals and stud bolt mount for secure mechanical and electrical connections; physical dimensions approximately φ76.2 × 105 mm (L: 10.5 × D: 7.62 cm).
• Endurance & lifetime: Load life specified as 5000 hours with rated ripple current at 85 °C; capacitance change, tan δ, and leakage current limits are defined for post‑endurance performance.
• Charge–discharge durability: Designed to cope with high‑speed charge–discharge loading; datasheet defines endurance for repeated charge–discharge cycles (50 million cycles at a ΔV = rated × 0.3, 3 Hz).
• Operating temperature & stability: Rated for −40 °C to +85 °C with impedance stability (Z(−40 °C)/Z(+20 °C) ≤ 8 for 350–500 V models).
• Leakage current specification: After 5 minutes at rated voltage, leakage current is specified as not more than 3√V (µA) or 5 mA, whichever is smaller (measured at 20 °C).
• Regulatory compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverters: DC link and smoothing capacitor in inverter power supplies where sustained ripple current and long life at elevated temperature are required.
• AC servomotor drives: Energy buffering and regeneration circuits that demand high‑frequency ripple handling and rapid charge–discharge capability.
• Regenerative power circuits: High‑frequency regenerative voltage environments that benefit from the capacitor’s specified high ripple current and charge‑discharge endurance.
• General power supplies: Bulk energy storage and smoothing in industrial power electronics and motor control systems requiring rugged stud‑mount capacitors.

Unique Advantages

• High ripple‑current handling: Explicit ripple ratings at both 120 Hz (17.8 A) and 100 kHz (24.92 A) support demanding AC and high‑frequency regenerative loads.
• Smaller footprint for the class: LNC series is specified as smaller sized with higher ripple current than comparable LNX/LNK series parts, enabling space‑constrained designs without sacrificing performance.
• Long elevated‑temperature life: 5000‑hour load life at 85 °C under rated ripple ensures predictable long‑term behavior in hot industrial environments.
• Robust charge–discharge endurance: Specified endurance to 50 million charge–discharge cycles validates suitability for repeated regenerative events and fast switching conditions.
• Secure mechanical mounting: Stud bolt mount and screw terminals provide reliable electrical contact and mechanical stability for heavy current and vibration‑prone installations.
• Standards‑level leakage and stability: Leakage current and impedance stability are specified, supporting predictable system design margins and qualification testing.
