LKS1J103MESB

The LKS1J103MESB is an aluminum electrolytic capacitor in a snap-in, radial can package designed for audio equipment and general-purpose electronic applications. It provides bulk capacitance (10 mF) at a rated voltage of 63 V in a smaller-sized snap-in form factor intended as an upgrade from small standard capacitors to help improve tone quality.

This RoHS-compliant component (Nichicon LKS series) is polarized, specified for operation from -40°C to +85°C, and is endurance-rated for 1000 hours at 85°C. Key electrical characteristics include a tolerance of ±20% (measured at 120 Hz, 20°C) and a rated ripple current of 4.4 A at 120 Hz.

Key Features

• Bulk Capacitance & Voltage — 10 mF nominal capacitance at a 63 V rated voltage, providing substantial energy storage for audio and general-purpose circuits.
• Snap-in Radial Can Package — Snap-in terminal mounting and radial, can-type package for secure PCB installation and mechanical stability.
• Audio-oriented, Smaller-sized — Marketed for audio equipment and described as smaller-sized with an intended effect of improving tone quality when used as a replacement for small standard products.
• Ripple Current Rated — Rated ripple current of 4.4 A at 120 Hz, specified for the intended measurement frequency used in the datasheet.
• Tolerance & Loss Characteristics — Capacitance tolerance of ±20% (120 Hz, 20°C). Tangent of loss angle (tan δ) is specified and measured at 120 Hz, 20°C per series documentation.
• Leakage Current Specification — Leakage current after 5 minutes at rated voltage and 20°C is specified as not more than 3√CV (μA), where C is rated capacitance (μF) and V is voltage (V).
• Temperature Range & Endurance — Operating temperature range −40°C to +85°C with an endurance rating of 1000 hours at 85°C; after endurance testing, capacitance change and leakage follow the series limits.
• RoHS Compliant — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size — Size dimension listed as L: 5 × D: 3 cm for PCB and mechanical planning.

Typical Applications

• Audio Equipment — Intended for use in audio equipment where replacement from smaller standard capacitors can contribute to improved tone quality.
• General-Purpose Electronics — Suitable for general-purpose circuits requiring a polarized, high-capacitance snap-in electrolytic capacitor within the specified temperature and endurance limits.
• Component Upgrades / Replacements — Used as a smaller-sized upgrade or replacement to standard parts where greater bulk capacitance and rated ripple performance are required.

Unique Advantages

• Designed for Audio Upgrade — Positioned specifically for audio equipment replacement use to help improve tone quality compared with smaller standard products.
• High Bulk Capacitance at 63 V — 10 mF at 63 V provides substantial charge storage for power filtering and decoupling needs within the datasheet limits.
• Measured Ripple Capability — Specified ripple current of 4.4 A at 120 Hz gives a verifiable performance parameter for AC ripple environments.
• Robust Thermal Endurance — Rated for 1000 hours at 85°C, with post-test limits for capacitance, tan δ, and leakage defined in the series documentation.
• Secure Snap-in Mounting — Snap-in radial can construction enables firm PCB retention and straightforward assembly for chassis-mounted and board-mounted designs.
• Regulatory Compliance — RoHS-compliant construction supports regulatory requirements for restricted substances.
