LKX2D182MESC45

The LKX2D182MESC45 is an aluminum electrolytic capacitor in a snap-in radial can designed for audio equipment and switching power supplies. It delivers 1.8 mF capacitance at a 200 V rating and is part of Nichicon’s LKX 105°C standard series, engineered with selected materials to achieve superior acoustic sound.

Its snap-in mounting and polarized construction make it suitable for general-purpose power filtering and energy storage in high-temperature environments, while meeting RoHS (2011/65/EU,(EU)2015/863) requirements.

Key Features

• Capacitance & Voltage 1.8 mF capacitance rated at 200 V with ±20% tolerance for predictable energy storage.
• High-temperature Endurance Rated for operation from –40°C to +105°C and specified endurance of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Snap-in Package Radial, can-type snap-in mounting for secure mechanical and electrical installation in power assemblies; physical size L: 4.5 × D: 3.5 cm, height seated max 1.772 inch.
• Ripple Current Performance Rated ripple current of 3.08 A at 120 Hz and 4.62 A at 50 kHz to support smoothing and decoupling in switched supplies.
• Audio-Optimized Materials Selected materials and construction intended to support superior acoustic sound as part of the LKX 105°C series.
• Polarized Electrolytic Polarized design appropriate for DC filtering and bulk energy storage in power circuitry.
• RoHS Compliant Conforms to RoHS directive (2011/65/EU,(EU)2015/863) for restricted substances.

Typical Applications

• Audio Equipment — Bulk filtering and power supply smoothing where selected materials and 105°C endurance contribute to consistent acoustic performance.
