LKS1H472MESZ

The LKS1H472MESZ is an aluminum electrolytic capacitor in a snap-in terminal, radial can package designed for audio equipment and general-purpose power filtering. It offers a compact footprint and is specified to improve tone quality when used as a replacement for smaller standard capacitors.

Key electrical and reliability specifications include a capacitance of 4.7 mF, a rated voltage of 50 V, an operating temperature range of −40 °C to +85 °C, and RoHS compliance (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance and Voltage: 4.7 mF nominal capacitance with a rated voltage of 50 V and a tolerance of −20% to +20%.
• Audio-oriented Design: Snap-in terminal construction and smaller-sized LKS series packaging intended for audio equipment; the series notes a measurable tone-quality improvement when replacing smaller standard parts.
• High Ripple Capability: Rated ripple current of 2.55 A at 120 Hz (low-frequency ripple specification).
• Thermal and Endurance Performance: Operating temperature range −40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C.
• Leakage Current Specification: Leakage current after 5 minutes at 20 °C is specified as not more than 3√(C·V) μA (C in μF, V in V), per the product series specification.
• Package and Mounting: Radial, can-style snap-in package for board-level snap-in mounting; physical dimensions L: 4.0 cm × D: 2.2 cm.
• Polarized Construction: Polarized aluminum electrolytic capacitor for DC filtering and smoothing applications.
• RoHS Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment: Power supply smoothing and decoupling in amplifiers and audio signal circuits where improved tone quality is desired by upgrading from smaller standard capacitors.
• Consumer Electronics: General-purpose DC filtering and bulk energy storage in compact equipment designs that require a snap-in radial can package.
• Replacement and Repair: Direct replacement in legacy or upgraded audio power supplies to achieve improved audible performance while maintaining board-mount convenience.

Unique Advantages

• Compact, audio-focused form factor: Smaller-sized LKS series construction enables upgrades in space-constrained audio equipment without switching to a different mounting style.
• Measurable tone improvement: Engineered for audible-quality enhancement when used as a replacement for small standard capacitors, per the series description.
• Robust ripple handling: 2.55 A ripple current rating at 120 Hz supports high-demand smoothing in audio power supplies.
• Wide operating range and proven endurance: −40 °C to +85 °C operation and 1000 hours endurance at 85 °C provide predictable performance over typical equipment lifecycles.
• Defined leakage behavior: Leakage current bounded by the 3√(C·V) μA rule gives a verifiable condition for design verification and margining.
• RoHS compliance: Meets current RoHS requirements for use in modern, regulated product designs.
