LNC2V332MTEG

The LNC2V332MTEG is a Nichicon LNC series aluminum electrolytic capacitor in a screw‑terminal (stud) can package. It is a polarized, smaller‑sized power capacitor rated at 350 V with a capacitance of 3.3 mF (3300 μF), designed for industrial power electronics requiring high ripple handling and robust charge‑discharge endurance.

Optimized for inverter circuitry and high‑frequency regenerative voltage in AC servomotors and general inverters, this part delivers high ripple current capability, long load life at elevated temperatures, and a compact footprint for stud‑mount installations.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 μF) nominal capacitance at a rated voltage of 350 V with ±20% tolerance.
• High Ripple Current — Rated ripple current of 14 A at 120 Hz and 19.6 A at 100 kHz, supporting demanding AC and high‑frequency applications.
• Temperature and Life — Operating range −40°C to +85°C with a load life of 5000 hours at 85°C when subjected to rated ripple current.
• Mounting & Package — Stud bolt mount with radial can and screw terminals for secure electrical and mechanical connections in power assemblies.
• Robust Endurance — Verified endurance for charge‑discharge behavior (50 million cycles at ΔV = rated × 0.3, 3 Hz), with post‑test limits on capacitance, tan δ and leakage current.
• Leakage & Insulation — Leakage current specified as not more than 3√(V) μA or 5 mA (whichever is smaller) after 5 minutes; insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Safety & Withstand — No abnormality under AC 2500 V for 1 minute between terminal and bracket.
• Design Size — Compact dimensions L: 8.0 cm × D: 6.35 cm, enabling space‑efficient power designs.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Bulk and smoothing capacitance for inverter DC buses where high ripple current and reliable operation at 350 V are required.
• AC Servomotor Regeneration — Handles high‑frequency regenerative voltage and rapid charge‑discharge cycles typical in servo drives.
• High‑Speed Charge‑Discharge Systems — Suited for circuits that demand repeated high‑rate cycling, backed by endurance testing to 50 million cycles.
• Power Supplies for Industrial Equipment — Provides stabilized DC link capacitance with long life at elevated ambient temperatures and robust leakage/insulation characteristics.

Unique Advantages

• High ripple capability: Measured ripple ratings of 14 A (120 Hz) and 19.6 A (100 kHz) reduce stress on downstream components and improve system stability in high‑current applications.
• Long operational life at elevated temperature: 5000 hours at 85°C under rated ripple current supports reliable long‑term operation in industrial environments.
• Charge‑discharge durability: Endurance to 50 million charge‑discharge cycles minimizes maintenance and supports high‑duty‑cycle applications.
• Secure mechanical mounting: Stud bolt mount with screw terminals ensures reliable electrical contact and straightforward installation in power assemblies.
• Compact form factor: Smaller physical dimensions for the LNC series help save PCB/assembly space while maintaining high performance.
• Measured insulation and leakage limits: Defined leakage current formula and >100 MΩ insulation resistance at 500 V provide predictable performance for safety and design compliance.
