LNT2W102MSEF

The Nichicon LNT2W102MSEF is a screw-terminal aluminum electrolytic capacitor offering 1 mF (1000 µF) capacitance at a 450 V rated voltage. It is part of the LNT series of 105°C standard, screw-terminal aluminum electrolytic capacitors designed for general-purpose applications.

This device targets applications that require high voltage and high capacitance in a robust, serviceable screw-terminal package. Key value propositions include high-voltage capability, elevated operating temperature rating, and a long rated life under ripple current at 105°C.

Key Features

• Capacitance & Tolerance — 1000 µF nominal capacitance with tolerance of -20% to +20% (±20% at 120 Hz, 20°C).
• Rated Voltage — 450 V DC nominal rating for high-voltage applications within the LNT series range.
• Temperature Range & Endurance — Operating temperature -25°C to +105°C with a rated load life of 5000 hours at 105°C.
• Ripple Current Performance — Low-frequency ripple current 7.0 A (at 120 Hz) and high-frequency ripple current 9.8 A (at 100 kHz), supporting AC ripple handling across frequency ranges.
• Leakage and Loss — Specified leakage current 2010 µA and tan δ = 0.2 (measured at 20°C, 120 Hz) for predictable loss and insulation behavior.
• Mounting & Package — Screw terminal mounting; radial can with screw terminals. For the φ51 size, terminal pitch and hardware are sized for M5 bolts.
• Size & Form Factor — Diameter φ51 mm and length 100 mm (dimensions: D: 5.1 cm × L: 10 cm), suitable for panel- or chassis-mounted, serviceable installations.
• Compliance & Packaging — RoHS-compliant and supplied in cardboard packing; product is in mass production.

Typical Applications

• General purpose power systems — Provides high-voltage bulk capacitance and ripple handling where 1 mF at 450 V and operation to 105°C are required.
• High-voltage energy storage — Use for localized DC energy storage and smoothing in systems that demand elevated voltage rating and sustained ripple endurance.
• Field-serviceable equipment — Screw-terminal construction and large form factor facilitate replacement and secure mounting in serviceable assemblies.

Unique Advantages

• High-voltage and high-capacitance combination: 450 V rating paired with 1000 µF capacitance enables compact high-energy storage in a single component.
• Extended high-temperature endurance: Rated for operation to 105°C with a 5000-hour life at that temperature, supporting long-term operation under rated ripple conditions.
• Broad ripple-frequency capability: Specified ripple current values at both 120 Hz (7.0 A) and 100 kHz (9.8 A) provide predictable performance across low and high ripple frequencies.
• Serviceable screw-terminal mounting: Radial can with screw terminals and M5 nominal bolt sizing (φ51) allow secure, maintainable installation in chassis or bracket-mounted designs.
• Measured electrical stability: Defined tan δ (0.2 at 20°C, 120 Hz) and a quantified leakage current (2010 µA) support predictable circuit behavior and design margining.
• RoHS-compliant, production-ready supply: Mass-production status and RoHS compliance simplify procurement and regulatory planning.
