LKS1E273MESB

The LKS1E273MESB is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general-purpose electronic applications. It delivers high capacitance in a smaller-sized, radial can package intended for improvements in tone quality when upgrading from smaller standard capacitors.

Key electrical characteristics include a rated capacitance of 27 mF at 25 V, polarization, and RoHS compliance (2011/65/EU, (EU)2015/863), making it suitable for designers seeking a high-capacitance, leaded solution with defined thermal and reliability limits.

Key Features

• Capacitance & Voltage — 27 mF capacitance rated at 25 V for bulk energy storage and smoothing in power circuits.
• Snap-in Radial Package — Snap-in terminal mounting for reliable mechanical retention and through-hole assembly in PCB layouts.
• Audio-Targeted Design — Specified for audio equipment with a smaller-sized construction intended to improve tone quality compared to smaller standard products.
• Environmental Compliance — RoHS compliant to 2011/65/EU and (EU)2015/863 requirements.
• Operating Range & Reliability — Rated for operation from −40 °C to +85 °C with a specified lifetime of 1000 hours at 85 °C.
• Electrical Performance — Capacitance tolerance of −20% to +20% and rated ripple current of 4.2 A at 120 Hz (measurement basis provided).
• Form Factor — Radial can, snap-in package with physical size L: 5 × D: 3 cm (and seated height specification available in product data).

Typical Applications

• Audio Equipment — Used as a replacement or upgrade capacitor to improve tone quality in amplifiers, preamplifiers, and other audio signal paths where higher bulk capacitance is required.
• General-Purpose Power Electronics — Bulk filtering and energy storage in power supply sections of consumer and pro-audio electronics.
• Component Upgrades — Direct replacement for smaller standard capacitors to increase filter capacitance and affect system audio characteristics.

Unique Advantages
