LKX2E561MESA40

The LKX2E561MESA40 is a snap-in aluminum electrolytic capacitor from Nichicon's LKX series, designed for audio equipment and switching power supply applications. It delivers 560 µF at 250 V in a φ25 × 40 mm radial can with snap-in terminals for secure mounting and assembly.

Engineered for reliability under elevated temperatures, this part is rated for 2000 hours at 105°C and is RoHS compliant, making it suitable for designs that require sustained performance, audible-quality materials, and robust ripple handling.

Key Features

• Capacitance & Voltage — 560 µF rated capacitance with a 250 V rated voltage and capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Package & Mounting — Snap-in, radial can configuration (φ25 × 40 mm) for reliable mechanical retention in power and audio assemblies.
• High‑Temperature Endurance — Specified for 2000 hours at 105°C under rated voltage and ripple, supporting long-term operation at elevated temperatures.
• Ripple Current Capability — Low-frequency ripple current of 1.5 A at 120 Hz and high-frequency ripple current of 2.25 A at 50 kHz to support smoothing and filtering in power stages.
• Electrical Loss — Tangent of loss angle (tan δ) value of 0.15 (measured at 120 Hz, 20°C) for predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 1120 µA after voltage application, enabling predictable bias behavior in circuits.
• Operating Range & Polarization — Polarized electrolytic capacitor rated for operation from −40°C to +105°C.
• Manufacturing & Packaging — Tray packing and mass-production availability for volume designs.

Typical Applications

• Audio Equipment — Used in audio power supplies and signal-chain power filtering where selected materials and 105°C endurance support acoustic performance.
• Switching Power Supplies — Bulk smoothing and ripple filtering in switching regulators, supported by specified ripple currents at both low and high frequencies.
• General Purpose Power Electronics — Energy storage, decoupling, and filtering roles in industrial and commercial electronic assemblies operating within −40°C to +105°C.

Unique Advantages

• Designed for elevated-temperature operation — Rated 2000 hours at 105°C to help maintain capacitance, tan δ, and leakage characteristics in hot operating environments.
• Dual-frequency ripple performance — Published ripple current figures at 120 Hz and 50 kHz (1.5 A and 2.25 A respectively) give designers clear margins for both mains-frequency and switching-frequency applications.
• Audio-focused material selection — Series documentation cites selected materials to achieve superior acoustic sound, aligning the component to audio-grade power circuitry.
• Predictable electrical characteristics — Specified tan δ (0.15) and leakage current (1120 µA) provide measurable parameters for thermal and bias design calculations.
• Robust mounting for high-reliability assemblies — Snap-in radial can format offers stable mechanical retention for power modules and chassis-mounted circuits.
• RoHS compliant — Meets applicable RoHS directive requirements for restricted substances.
