Overview of LKX2G151MESY45 – 400 V, 150 µF Snap‑in Aluminum Electrolytic Capacitor

The LKX2G151MESY45 is a snap‑in, radial can aluminum electrolytic capacitor designed for audio equipment and switching power supplies. It provides 150 µF capacitance at a 400 V rating with materials selected to support superior acoustic sound quality while meeting general‑purpose power filtering needs.

Built for higher operating temperatures, the part is specified for operation from −25 °C to 105 °C and is RoHS‑compliant, making it suitable for applications that require elevated temperature endurance and regulatory compliance.

Key Features

  • Capacitance & Voltage — 150 µF rated capacitance at 400 V, with capacitance tolerance of ±20% (120 Hz, 20 °C).
  • Snap‑in Radial Can Package — Snap‑in terminal mounting for secure board or chassis installation in a compact L: 4.5 × D: 2 cm package.
  • High‑Temperature Endurance — Qualified for operation up to 105 °C with an endurance specification of 2000 hours at 105 °C under D.C. bias plus rated ripple current.
  • Ripple Current Performance — Rated ripple current of 850 mA at 120 Hz and 1.216 A at 50 kHz to support switching supply and filtering duty cycles.
  • Low‑Temperature Stability (400–450 V range) — Impedance stability characterized with Z(−25 °C) / Z(+20 °C) up to 8, providing predictable performance across temperature extremes.
  • Polarized Design — Polarized electrolytic construction for energy storage and smoothing applications.
  • Low Leakage Current Specification — Series leakage current defined as I ≤ 3√3V (µA) after 5 minutes at 20 °C, supporting reliable DC performance.
  • Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

  • Switching Power Supplies — Bulk filtering and energy storage for power rails where 400 V rating and high ripple capability are required.
  • Audio Equipment — Selected materials and construction targeted to achieve superior acoustic sound in power supply and coupling/filter roles.
  • General‑Purpose Power Filtering — Capacitor for industrial and consumer power electronics requiring polarized, high‑voltage capacitance with elevated temperature endurance.

Unique Advantages

  • High‑temperature reliability: Rated to 105 °C with a 2000‑hour endurance specification at that temperature to support designs exposed to sustained thermal stress.
  • Strong ripple handling: Specified ripple current values (850 mA at 120 Hz, 1.216 A at 50 kHz) provide quantifiable capability for switching and high‑frequency environments.
  • Secure, serviceable mounting: Snap‑in radial can package simplifies mechanical retention and replacement in chassis or board assemblies.
  • Acoustic‑aware material selection: Materials were selected for improved acoustic characteristics in audio equipment applications.
  • Predictable low‑temperature behavior: Impedance characterization for the 400–450 V range (Z(−25 °C)/Z(+20 °C) up to 8) helps designers account for low‑temperature performance.
  • Regulatory readiness: RoHS compliance supports deployment in regions requiring restricted‑substance adherence.

Why Choose LKX2G151MESY45?

The LKX2G151MESY45 positions itself as a robust, high‑voltage electrolytic capacitor option where elevated temperature endurance, measurable ripple handling, and audio‑focused material selection matter. Its snap‑in radial can form factor and clear series specifications make it suitable for designers of switching power supplies, audio power stages, and general‑purpose power filtering who need predictable electrical and thermal behavior.

Manufactured by Nichicon and specified with clear endurance, leakage, and impedance criteria, this capacitor supports long‑term reliability in demanding thermal and ripple environments while meeting RoHS requirements.
