LKX2W101MESZ30

The LKX2W101MESZ30 is a 100 µF, 450 V aluminum electrolytic capacitor in a radial, snap‑in can package from Nichicon's LKX series. It is a polarized, general‑purpose component designed for use in audio equipment and switching power supplies.

Engineered as part of Nichicon’s 105°C standard series, this part uses selected materials to achieve superior acoustic sound and is RoHS compliant. It offers high‑voltage bulk capacitance, defined ripple ratings, and published endurance data for predictable performance in demanding thermal environments.

Key Features

• Electrical characteristics — 100 µF capacitance at a 450 V rated voltage with ±20% tolerance; polarized design for DC filtering and energy storage applications.
• Acoustic-focused material selection — Selected materials and series design aimed at delivering superior acoustic sound for audio applications, as specified by the LKX series description.
• Package and mounting — Radial, can-style snap‑in package for secure board mounting and mechanical stability in power assemblies.
• Thermal and endurance ratings — Operating temperature range of −25°C to +105°C with an endurance rating of 2000 hours at 105°C under D.C. bias plus rated ripple current as defined in the LKX series specifications.
• Ripple current performance — Rated ripple current of 690 mA at 120 Hz and 986.7 mA at 50 kHz; datasheet frequency coefficients for 400–450 V parts show increased allowable ripple at higher frequencies (coefficient ~1.43 at 50 kHz or more).
• Leakage current specification — Leakage current conforms to the LKX series formula: I ≤ 3√3V (µA) after 5 minutes’ application of rated voltage at 20°C, per the published datasheet.
• Size — Compact radial can dimensions: L: 3 × D: 2.2 cm, suitable for space‑constrained power designs.
• Regulatory — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio equipment — Bulk filtering and decoupling where selected materials and series design contribute to acoustic performance and sound quality.
• Switching power supplies — Energy storage and smoothing in high‑voltage power rails for power conversion stages.
• General‑purpose high‑voltage filtering — Use in industrial or instrumentation power circuits requiring 450 V rated bulk capacitance and defined ripple capability.
