LNT2G331MSECBN

The LNT2G331MSECBN is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNT series. It delivers 330 µF capacitance at a 400 V rating in a radial can with screw terminals, designed for general‑purpose power applications that require high voltage handling and robust mechanical connections.

Key value is long operational life and thermal endurance: rated for operation from −25°C to +105°C with a 5,000 hour life at 105°C, making it suitable where sustained high‑temperature ripple duty and service longevity are required.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance with a 400 V rated voltage, specified ±20% tolerance at 120 Hz, 20°C.
• Long Endurance: Rated for 5,000 hours at +105°C under rated ripple current and DC bias (per LNT series endurance specification).
• Temperature Range: Operational range from −25°C to +105°C, enabling deployment in elevated ambient environments within that window.
• Ripple Current Performance: 2.3 A at 120 Hz and 3.22 A at 100 kHz, supporting continuous filtering and smoothing under ripple load.
• Screw Terminal Package: Radial can with screw terminals (φ35 × 80L footprint) for secure, low‑impedance power connections and easy serviceability.
• Electrical Loss: Specified tan δ = 0.2 (maximum as provided), supporting predictable dissipation characteristics at rated conditions.
• Compliance & Packaging: RoHS‑compliant construction; supplied in cardboard packing for mass production handling.

Typical Applications

• General‑purpose power filtering: Bulk smoothing and DC link applications where 400 V rating and 330 µF capacitance are required.
• High‑temperature installed environments: Systems that operate up to +105°C and require capacitors rated for extended life at elevated temperatures.
• Serviceable power modules: Equipment designs that benefit from screw‑terminal mounting for secure electrical connection and straightforward maintenance.

Unique Advantages

• High‑voltage capability: 400 V rating enables use in medium‑to‑high voltage power stages without additional series stacking.
• Designed for endurance: 5,000 hour life at 105°C provides predictable aging and replacement planning for long‑running equipment.
• Robust mounting and connection: Screw terminals offer low contact resistance and mechanical reliability compared with soldered leads.
• Measurable ripple handling: Specified ripple current values at 120 Hz and 100 kHz allow designers to size capacitors against real ripple loads.
• Wide ambient range: −25°C to +105°C operation supports deployment across varied thermal conditions within that range.
• Regulatory compliance: RoHS‑compliant materials and manufacturing reduce regulatory risk for environmental directives covered in the product data.
