LKSH2103MESC

The LKSH2103MESC is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general-purpose electronic applications. It delivers a large 10 mF capacitance with a 71 V rated voltage in a radial, can-style snap-in package.

As a smaller-sized LKS series option, the part is marketed to improve tone quality when replacing smaller standard capacitors and is RoHS compliant (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Voltage — 10 mF capacitance with a rated voltage of 71 V for high-energy storage in audio and power-filtering circuits.
• Package & Mounting — Snap-in terminal, radial can package for secure board or chassis mounting and straightforward assembly.
• Electrical Tolerance — Capacitance tolerance of ±20% (measured at 120 Hz, 20°C) to match design expectations for bulk and smoothing applications.
• Ripple Handling — Rated ripple current of 4.6 A at 120 Hz, suitable for audio amplifier filtering and power decoupling where AC ripple is present.
• Polarized — Polarized construction for use in DC power rails and electrolytic applications requiring polarity-aware components.
• Temperature & Endurance — Operating range of −40°C to +85°C with a rated lifetime of 1000 hours at 85°C; endurance specifications from the LKS series apply after voltage-aging.
• Leakage Current — After 5 minutes at rated voltage (20°C), leakage current is specified as not more than 3√CV (μA) [C: μF, V: V], per LKS series characteristics.
• Audio-focused Design — LKS series notes it is “Smaller and high-tone quality than LKG TYPE-1 grade,” indicating a focus on tone-quality improvement when used as a replacement part.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Physical Size — Body dimensions: L: 4.5 × D: 3.5 cm for compact installation in rack or chassis-mounted audio equipment.

Typical Applications

• Audio Amplifiers — Bulk filtering and smoothing for amplifier power rails where large capacitance and high ripple current handling improve transient response and stability.
• Consumer Audio Systems — Replacement or upgrade in audio equipment to achieve tone-quality improvement as part of system-level tuning.
• General Purpose Power Filtering — DC rail decoupling and storage in general-purpose electronic equipment within the −40°C to +85°C operating range.

Unique Advantages

• Audio-oriented series design — Marketed small-size variant of the LKS series with a focus on tone-quality improvement versus earlier LKG TYPE-1 grade parts.
• High stored energy in compact form — 10 mF at 71 V provides substantial energy capacity for smoothing and transient support in compact audio and power circuits.
• Robust ripple capability — 4.6 A ripple current rating at 120 Hz helps maintain performance under cyclic AC loading common in audio power sections.
• Clear endurance specification — 1000 hours at 85°C endurance (series specification) enables predictable lifetime planning in thermal environments up to 85°C.
• Measured leakage specification — Leakage current defined by 3√CV after 5 minutes at rated voltage supports predictable bias behavior during design validation.
• Regulatory compliance — RoHS compliance supports use in designs that require restricted-substance conformance.
