LKX2E271MESZ30

The LKX2E271MESZ30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKX series, specified for audio equipment and switching power supplies. It combines a 270 µF capacitance with a 250 V rated voltage in a radial snap-in can designed for robust board mounting.

Selected materials and construction in the LKX series are targeted to deliver superior acoustic sound performance while providing reliable bulk energy storage and smoothing across a −40 °C to 105 °C operating range. The product is RoHS compliant.

Key Features

• Electrolytic Core – Polar: Aluminum electrolytic construction with polarized terminals for high-capacitance DC applications.
• Capacitance & Voltage: 270 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance (120 Hz, 20 °C).
• Temperature & Lifetime: Rated for operation from −40 °C to 105 °C with an endurance specification of 2000 hours at 105 °C under rated ripple and DC bias.
• Ripple Current Capability: Rated ripple current performance includes 1.1 A at 120 Hz and 1.65 A at 50 kHz, supporting typical power-supply filtering requirements.
• Package & Mounting: Radial, can-style snap-in package for secure, low-profile board installation (size: L: 3 × D: 2.2 cm).
• Acoustic-focused Materials: Manufactured with selected materials intended to improve acoustic sound quality in audio applications.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Identification: Marked with gold-color lettering on a black sleeve for clear on-board identification.

Typical Applications

• Audio Equipment: Bulk filtering and smoothing in audio power stages where component selection and materials help preserve sound quality.
• Switching Power Supplies: Output and bulk storage in SMPS designs requiring high-voltage capacitance and reliable ripple handling.
• General Purpose Power Electronics: Energy buffering and decoupling in industrial and commercial power circuits that operate across a wide temperature range.

Unique Advantages

• Designed for audio performance: Selected materials and LKX series construction target improved acoustic characteristics for audio signal chains.
• High-temperature endurance: 2000-hour endurance at 105 °C provides predictable life under elevated operating temperatures.
• Strong ripple handling: Specified ripple current values at both low and high frequencies (1.1 A at 120 Hz, 1.65 A at 50 kHz) support power-supply stability and reduced heating.
• Secure snap-in mounting: Radial snap-in can packaging simplifies mechanical retention and assembly in high-reliability boards.
• Regulatory-ready materials: RoHS compliance supports use in designs requiring restricted-substance conformance.
• Clear specification window: Standardized LKX series datasheet values (capacitance tolerance, temperature range, endurance) make performance easy to validate during design.
