LKS1H153MESC

The LKS1H153MESC is an aluminum electrolytic capacitor from Nichicon’s LKS series featuring a snap-in terminal design in a radial can package. It is specified for audio equipment and described as smaller-sized for applications where compact, high-capacitance electrolytic solutions are required.

Designed for general-purpose use, this polarized capacitor offers 15 mF capacitance at a 50 V rating, RoHS compliance, and a documented effect of tone quality improvement when replacing smaller standard products.

Key Features

• Capacitance & Voltage — Rated capacitance of 15 mF with a 50 V rating and a tolerance of ±20%.
• Package & Mounting — Radial, can snap-in terminal type with physical dimensions L: 4.5 × D: 3.5 cm for compact board layouts.
• Audio-Focused Design — Specified for audio equipment and noted for tone quality improvement when used as a replacement for smaller standard capacitors.
• Polarized Electrolytic — Polarized construction appropriate for DC electrolytic capacitor applications.
• Temperature & Endurance — Operating range −40°C to +85°C with an endurance rating of 1000 hours at 85°C.
• Ripple Current — Rated ripple current of 4.55 A at 120 Hz (measurement frequency: 120 Hz).
• Leakage Current Specification — Leakage current meets the datasheet requirement: after 5 minutes’ application of rated voltage at 20°C, leakage current is not more than 3√CV (µA), where C is µF and V is volts.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Intended for use in audio equipment where replacing smaller standard capacitors can produce a measurable tone quality improvement.
• General-Purpose Electronic Equipment — Suitable for general-purpose designs that require a snap-in radial can aluminum electrolytic capacitor.
• Audio Upgrades and Retrofits — Appropriate for upgrading capacitors in existing audio circuits to pursue improved tone characteristics via larger capacitance.

Unique Advantages

• Tone Quality Improvement: Specified effect of improved tone quality when replacing smaller standard products, addressing audio design goals directly.
• High Capacitance at 50 V: 15 mF rating provides substantial energy storage at a 50 V working voltage for designs requiring that specification.
• Defined Ripple Handling: 4.55 A ripple current rating at 120 Hz supports operation under significant AC ripple conditions per the datasheet.
• Specified Endurance: Rated for −40°C to +85°C operation with a documented 1000-hour lifetime at 85°C for predictable long-term behavior within that envelope.
• Leakage Current Defined by Formula: Datasheet-defined leakage current limit (≤ 3√CV µA after 5 minutes at 20°C) enables predictable leakage behavior for design calculations.
• RoHS Compliance: Conforms to RoHS directive requirements (2011/65/EU, (EU)2015/863) for regulatory compatibility.
