LKX2E471MESA35

The LKX2E471MESA35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LKX series, offering 470 µF capacitance at a 250 V rating. It is engineered for use in audio equipment and switching power supplies where reliable high‑voltage smoothing and acoustic performance are required.

Designed for demanding thermal environments, this polarized capacitor supports operation from −40°C to +105°C and is RoHS compliant (2011/65/EU, (EU)2015/863), making it suitable for a range of general‑purpose power applications.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 250 V rated voltage for high‑voltage smoothing and energy storage.
• Snap‑in Radial Can Package — Snap‑in terminal type in a radial can package for secure PCB mounting in power and audio assemblies.
• Audio‑Oriented Materials — LKX series uses selected materials intended to achieve superior acoustic sound for audio equipment applications.
• Wide Temperature Range — Rated for −40°C to +105°C operation to cover typical commercial and industrial ambient conditions.
• High Temperature Endurance — Endurance defined as 2000 hours at 105°C under DC bias plus rated ripple current for predictable long‑term performance.
• Ripple Current Performance — Specified ripple current: 1.4 A at 120 Hz and 2.1 A at 50 kHz to support both low‑ and high‑frequency filtering needs.
• Polarized with ±20% Tolerance — Polarized electrolytic device with capacitance tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• RoHS Compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Power supply smoothing and decoupling where selected materials contribute to improved acoustic characteristics.
• Switching Power Supplies — DC link smoothing and ripple filtering in switched‑mode power supply stages at higher voltages.
• General‑Purpose Power Filtering — Bulk energy storage and decoupling in electronic systems requiring 470 µF at 250 V.
