LKS1H103MESC

The LKS1H103MESC is an aluminum electrolytic capacitor in a snap‑in terminal package designed for audio equipment and general-purpose power filtering. It provides a 10 mF capacitance at a 50 V rating with a compact, smaller-sized form factor and is RoHS compliant.

Engineered for applications requiring bulk energy storage and low-frequency ripple handling, this polarized snap-in capacitor offers a balance of capacitance, voltage tolerance, and mechanical mounting suited to chassis or board-mounted power sections.

Key Features

• Capacitance & Voltage — 10 mF rated capacitance at 50 V with a tolerance of ±20%, suitable for bulk filtering and smoothing in power rails.
• Package & Mounting — Snap-in terminal, radial can package for secure mechanical mounting and straightforward assembly into chassis or PC boards.
• Operating Range & Lifetime — Rated for operation from −40°C to +85°C with a specified endurance of 1000 hours at 85°C.
• Ripple Performance — Low-frequency ripple current capability of 3.85 A at 120 Hz for effective smoothing of rectified supplies.
• Leakage Current — Defined leakage characteristic: after 5 minutes’ application of rated voltage at 20°C, leakage current is not more than 3√CV (μA), where C is capacitance (μF) and V is voltage (V).
• Audio‑Focused Design — Marketed for audio equipment with a smaller-sized construction that the manufacturer indicates can improve tone quality when used as a replacement for small standard products.
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Power supply smoothing and bulk storage in amplifiers and audio power supplies; intended to contribute to tone quality improvement when replacing smaller standard capacitors.
• General-Purpose Power Filtering — DC rail smoothing and energy buffering in a variety of electronic equipment that requires polarized electrolytic capacitance.
• Amplifier Power Sections — Bulk capacitance for preamp and power amplifier supplies where high capacitance and low-frequency ripple handling are needed.

Unique Advantages

• High Bulk Capacitance at 50 V — 10 mF provides significant energy storage for supply smoothing without exceeding the specified voltage rating.
• Snap‑In Mounting — Radial, snap-in can simplifies mechanical installation and secures the capacitor in chassis or board assemblies.
• Designed for Audio Use — Smaller-sized LKS series construction is positioned to enhance tone quality when used as an upgrade from smaller standard parts.
• Robust Thermal Endurance — Rated to operate down to −40°C and up to +85°C with a 1000 hour endurance at 85°C for predictable lifetime behavior under heat stress.
• Defined Leakage and Ripple Specs — Leakage current limit (3√CV μA after 5 minutes at 20°C) and 3.85 A ripple current at 120 Hz deliver verifiable electrical characteristics for design validation.
• Regulatory Compliance — RoHS compliance supports use in regions and products requiring restricted-substance adherence.
