LKSA2103MESA

The LKSA2103MESA is a snap-in terminal aluminum electrolytic capacitor designed for audio equipment and general-purpose power applications. It combines a compact, smaller-sized can with audio-oriented characteristics to support power smoothing and decoupling in audio circuits.

Key electrical characteristics include 10000 µF capacitance at a 42 V rating, a low-frequency ripple current capability of 3.5 A (120 Hz), and a rated operating temperature range of -40 °C to +85 °C, with an endurance rating of 1000 hours at 85 °C.

Key Features

• Capacitance and Voltage: 10000 µF (10 mF) nominal capacitance with a rated voltage of 42 V, suitable for bulk energy storage and smoothing in power rails.
• Audio-focused Design: Snap-in terminal type specified "for audio equipment" and described as "Smaller and high-tone quality," targeting improved tonal performance where specified.
• Ripple Current Capability: Low-frequency ripple current 3.5 A measured at 120 Hz, supporting moderate AC ripple in power-supply applications.
• Dissipation Factor (tan δ): tan δ = 0.3 at 20 °C, 120 Hz, indicating the capacitor’s loss characteristics under the stated measurement conditions.
• Leakage and Tolerance: Specified leakage current 1940 µA and capacitance tolerance of -20% to +20% (±20% at 20 °C, 120 Hz).
• Robust Operating Range: Rated for -40 °C to +85 °C with an endurance life of 1000 hours at 85 °C and defined post-test limits for capacitance change, tan δ, and leakage current.
• Package and Mounting: Snap-in radial can, compact size φ25 × 50 mm length, and supplied in tray packing for board-level assembly.
• RoHS Compliance: Compliant with RoHS directive as noted in the series documentation.

Typical Applications

• Audio Equipment: Bulk filtering and power-supply smoothing in amplifiers and audio electronics where the series is specified for tonal performance.
• Power Supply Reservoirs: Energy storage and decoupling for medium-voltage DC rails up to 42 V in general-purpose electronic equipment.
• Industrial Electronics: Decoupling and ripple suppression in control and consumer devices that operate within the -40 °C to +85 °C temperature range.

Unique Advantages

• Audio-centric construction: Designed and described for audio equipment use, offering a smaller form factor with reported tone-quality benefits where the series is applied.
• High capacitance in compact can: 10000 µF in a φ25 × 50 mm can provides significant bulk capacitance while minimizing board footprint.
• Reliable ripple handling: 3.5 A low-frequency ripple current rating at 120 Hz supports steady ripple absorption in power-supply applications.
• Defined endurance and stability: Endurance specified as 1000 hours at 85 °C with post-test limits for capacitance, tan δ, and leakage to verify long-term behavior under rated conditions.
• Tray packing for assembly: Supplied in tray packing to support handling and insertion for production workflows.
