LKX2E331MESA25

The LKX2E331MESA25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LKX series, specified for audio equipment and switching power supply applications. It combines a 330 µF capacitance with a 250 V rating in a compact radial can snap‑in package designed for reliable power filtering and smoothing.

Selected materials and construction target improved acoustic performance for audio systems, while a 2000‑hour endurance at 105°C, wide operating temperature range, and RoHS compliance support robust, long‑life installations.

Key Features

• Capacitance & Voltage — 330 µF capacitance rated at 250 V for bulk filtering and energy storage in power rails.
• Snap‑In Radial Can — Snap‑in mounting style and radial can package provide strong mechanical retention for PCB assembly in power modules and chassis‑mounted supplies.
• Operating Temperature & Endurance — Rated for −40°C to +105°C with an endurance specification of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Performance — Rated ripple currents include 1.2 A at 120 Hz and 1.8 A at 50 kHz. Frequency coefficients show increased allowable ripple at higher frequencies (for 200–250 V the coefficient reaches 1.50 at 50 kHz).
• Audio‑Focused Materials — Selected materials intended to achieve superior acoustic sound for audio equipment applications.
• Polarized with Standard Tolerance — Polarized capacitor with ±20% tolerance at 120 Hz, 20°C, suitable for conventional polarized power circuits.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory requirements for restricted substances.
• Compact Dimensions — 25 mm × 25 mm can size (L: 2.5 × D: 2.5 cm), enabling use where board space is constrained.
• Sleeve Marking — Identified with gold lettering on a black sleeve for clear polarity and series identification.

Typical Applications

• Audio switching power supplies — Bulk filtering and energy smoothing in switching regulators that feed audio stages, leveraging materials selected for acoustic performance.
• Professional and consumer audio equipment — Power rail decoupling and reservoir capacitance in amplifiers and powered audio devices.
• General purpose power filtering — DC link and smoothing capacitor in general purpose power supplies and electronic equipment where a polarized snap‑in solution is required.

Unique Advantages

• Audio‑oriented material selection: Construction chosen to support improved acoustic characteristics in audio applications.
• High‑temperature endurance: Rated for continuous operation and endurance testing at 105°C (2000 hours), helping ensure longevity in thermally demanding installations.
• Frequency‑responsive ripple capability: Ripple current ratings and published frequency coefficients allow designers to size capacitors accurately across low and high ripple frequencies.
• Robust snap‑in mounting: Snap‑in terminals provide secure mechanical retention for board and chassis assemblies, simplifying installation in power modules.
• Regulatory compliance: RoHS conformity supports deployments where restricted‑substance compliance is required.
• Compact, identifiable package: 25 mm × 25 mm radial can with gold‑on‑black sleeve marking eases identification and layout in dense assemblies.
