Overview of LKX2W271MESC30 – Snap-in 450 V, 270 µF Aluminum Electrolytic Capacitor

The LKX2W271MESC30 is a snap-in terminal aluminum electrolytic capacitor in Nichicon’s LKX series, specified for audio equipment and switching power supply applications. It delivers 270 µF capacitance at a 450 V rating in a radial, can-type snap-in package designed for general-purpose power filtering and energy storage.

Engineered for sustained operation up to 105 °C, the LKX2W271MESC30 combines high-voltage capability with snap-in mounting for reliable board retention and streamlined assembly in power electronic designs.

Key Features

  • Capacitance & Voltage — 270 µF capacitance rated at 450 V for high-voltage energy storage and bulk filtering in power rails.
  • Package & Mounting — Radial, can-type snap-in package provides secure snap-in terminal mounting for through-hole PCB applications.
  • Temperature & Lifetime — Rated for operation from −25 °C to +105 °C with an endurance specification of 2000 hours at 105 °C.
  • Ripple Current Performance — Specified ripple current values include 1.23 A at 120 Hz and 1.759 A at 50 kHz, supporting both low- and high-frequency filtering in switching environments.
  • Tolerance & Polarization — Capacitance tolerance of −20% to +20% and polarized construction; suitable where polarized electrolytics are required.
  • Compliance — RoHS compliant, meeting environmental directive requirements.
  • Compact Footprint — Physical size approximately L: 3 × D: 3.5 cm, offering a compact high-voltage solution for constrained layouts.

Typical Applications

  • Audio Equipment — Bulk filtering and energy storage in audio power supplies where stable DC rails are required for high-quality sound systems.
  • Switching Power Supplies — Input/output smoothing and decoupling in high-voltage switching regulators and converters.
  • General-Purpose Electronic Equipment — High-voltage filtering and energy storage across a range of industrial and consumer power designs.

Unique Advantages

  • High-Voltage Capability: 450 V rating enables use in elevated-voltage rails without additional series stacking.
  • Built for Elevated Temperatures: 105 °C rating with a 2000-hour endurance at that temperature supports reliable operation in thermally demanding environments.
  • Snap-In Mounting: Snap-in terminal design simplifies assembly and secures the capacitor on the PCB for robust mechanical retention.
  • Frequency-Span Ripple Specification: Defined ripple current at both 120 Hz and 50 kHz helps engineers assess suitability for both line-frequency and switching-frequency applications.
  • Regulatory Compliance: RoHS compliance supports environmentally conscious designs and market requirements.
