LKX2E561MESZ50

The LKX2E561MESZ50 is a snap-in aluminum electrolytic capacitor designed for audio equipment and power-supply applications. It combines 560 µF capacitance with a 250 V rating in a radial, snap-in can (φ22 × 50 mm) intended for reliable power filtering and energy storage in high-performance audio and switching power supplies.

Engineered for continuous operation up to 105°C and manufactured for mass production, this RoHS-compliant part targets designs that require high ripple handling, long endurance, and acoustically selected materials for improved sound characteristics.

Key Features

• Capacitance & Voltage: 560 µF nominal capacitance at a 250 V rated voltage, suitable for high-voltage filtering and energy storage tasks.
• Snap-in Radial Package: Radial, can-type snap-in mounting (φ22 × 50 mm) for secure board installation and straightforward assembly.
• High Ripple Capability: Rated ripple current of 1.5 A at 120 Hz and 2.25 A at high frequency (listed at 100 kHz), enabling effective handling of AC ripple in switching supplies.
• Thermal and Endurance Performance: Operating temperature range –40°C to +105°C with a rated life of 2000 hours at 105°C under DC bias plus rated ripple current.
• Electrical Characteristics: Low loss tangent (tan δ = 0.15) and specified leakage current (1,120 µA) for predictable performance in power circuits.
• Audio-Optimized Materials: Selected materials to achieve superior acoustic sound, making the part suitable where audio fidelity matters.
• Packaging: Supplied in tray packing for efficient handling in production environments.
• Regulatory Status: RoHS compliant.

Typical Applications

• Audio Equipment Power Supplies: Bulk and smoothing capacitor for amplifier and preamplifier power rails where acoustic characteristics are important.
• Switching Power Supplies: Input/output filtering and ripple suppression in switching converters used in audio or general-purpose power systems.
