LNK2G102MSEF

The LNK2G102MSEF is a Nichicon LNK series aluminum electrolytic capacitor in a screw-terminal radial can package. It provides 1000 µF capacitance at a 400 V rating with a polarized design and is intended for general-purpose power applications.

Key value propositions include a long rated life of 5000 hours at 85°C under rated ripple conditions, measurable ripple-current capability at multiple frequencies, and a compact φ51 × 65 mm can with screw terminals for secure chassis or bracket mounting.

Key Features

• Capacitance & Voltage — 1,000 µF rated capacitance at 400 V, tolerance ±20% (at 120 Hz, 20°C), suitable for high-voltage bulk energy storage in general-purpose designs.
• Lifetime & Temperature — Load life of 5,000 hours at 85°C when rated ripple current is applied; rated operating temperature range −25°C to +85°C.
• Package & Mounting — Radial can with screw terminals (φ51 × 65 mm overall), designed for secure mechanical attachment via bracket and M5 bolt pitch as specified in the series drawing.
• Ripple Current Performance — Rated ripple current of 5 A at 120 Hz and 7 A at 10 kHz, with frequency coefficients published in the series documentation for design calculation.
• Electrical Reliability — Leakage current specification after 5 minutes is not more than 3√(C·V) µA or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute without abnormality.
• Endurance & Stability — After DC bias plus rated ripple current for 5,000 hours at 85°C, capacitance change is within ±20% and dissipation factor/ESR changes remain within specified limits per the series endurance criteria.
• Loss Characteristics — Specified tangent of loss angle (tan δ) of 0.2 supporting predictable dissipation behavior at measurement conditions.
• Regulatory — RoHS compliant as declared for the series.

Typical Applications

• General-purpose power supplies — Provides bulk capacitance and high-voltage smoothing in general-purpose designs that require 400 V, 1000 µF screw-terminal capacitors.
• Chassis- or bracket-mounted industrial equipment — Radial can with screw terminals and M5 mounting provision allows secure installation in panel-mounted or bracketed power assemblies.
• High-voltage DC bus and energy storage in general-purpose systems — Rated voltage and long life at 85°C support use where sustained high-voltage bulk capacitance is needed for general-purpose applications.

Unique Advantages

• Long, defined service life: 5,000 hours at 85°C under rated ripple current provides predictable end-of-life planning for designs.
• High-voltage capability: 400 V rating enables use on high-voltage DC buses without series stacking complications.
• Robust mounting: Screw-terminal radial can and specified M5 bolt accommodation simplify secure mechanical installation and replacement.
• Known ripple performance: Published ripple-current ratings at 120 Hz and 10 kHz allow engineers to size capacitors for expected ripple loads.
• Measured leakage and insulation criteria: Leakage current limits, insulation resistance threshold, and voltage-withstand values give quantifiable electrical safety margins.
• RoHS compliance: Series-level compliance supports regulatory requirements for restricted substances.
