LKS1J122MESZ

The LKS1J122MESZ is a snap-in terminal aluminum electrolytic capacitor designed for audio equipment and other general-purpose applications. It combines a compact snap-in radial can package with a 1.2 mF capacitance and a 63 V rated voltage to support power-supply smoothing and tone-quality improvements when replacing smaller standard capacitors.

Built for durability in typical electronic environments, the LKS1J122MESZ is RoHS compliant and offers specified ripple current handling and a defined endurance profile for reliable operation in assemblies.

Key Features

• Capacitance & Tolerance — 1.2 mF capacitance with ±20% tolerance, suitable for bulk filtering and energy storage in audio and general-purpose circuits.
• Voltage Rating — 63 V rated voltage for use in higher-voltage DC rail and power-supply applications.
• Polarized Electrolytic — Polar construction for correct DC electrolytic application in power and audio circuits.
• Thermal Range & Endurance — Operating temperature range of −40°C to +85°C with a rated lifetime of 1000 hours at 85°C, supporting stable performance under typical operating conditions.
• Ripple Handling — Specified ripple current of 1.5 A at 120 Hz, enabling effective smoothing of low-frequency supply ripple.
• Package & Mounting — Snap-in radial can (snap-in terminal) package for secure PCB mounting and straightforward mechanical installation.
• Compact Footprint — Physical size approximately L: 2 × D: 2.2 cm for space-conscious designs.
• Environmental Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Power-supply smoothing and tone-quality improvement when replacing smaller standard electrolytic capacitors in amplifiers and audio circuits.
• General-Purpose Electronics — Bulk filtering and energy storage on DC rails in consumer and industrial electronic assemblies.
