LKSA2103MESB

The LKSA2103MESB is a snap-in aluminum electrolytic capacitor designed for audio equipment and general-purpose electronic applications. Its snap-in radial can package and polarization make it suitable for PCB-mounted power filtering and DC link roles where tonal quality improvement and reliable smoothing are required.

Key electrical characteristics include a 10 mF capacitance, 42 V rated voltage, and RoHS compliance, delivering a balance of capacitance, ripple handling and thermal endurance for compact audio and consumer electronic designs.

Key Features

• Capacitance & Voltage — 10 mF capacitance rated at 42 V for bulk energy storage and smoothing in power rails.
• Mounting & Package — Snap-in radial can package designed for secure PCB insertion and mechanical stability in through-hole assemblies.
• Operational Temperature — Rated for operation from −40 °C to +85 °C to support typical consumer and industrial audio environments.
• Endurance — Engineered for 1000 hours at 85 °C, meeting endurance requirements for sustained elevated-temperature operation.
• Ripple Performance — Low-frequency ripple current rating of 3.5 A at 120 Hz for effective smoothing of rectified power and low-frequency supply ripple.
• Tolerance & Polarization — Polarized capacitor with capacitance tolerance of −20% to +20%, enabling predictable selection for circuit design and replacements.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863), supporting restricted-substance requirements.

Typical Applications

• Audio Equipment — Intended for use in amplifiers and audio power supplies where replacement from smaller standard parts can improve tonal quality and smoothing.
• Power Supply Filtering — Bulk decoupling and smoothing on DC rails in consumer and professional electronics requiring stable supply under ripple loads.
• General Purpose Electronics — Through-hole, snap-in installation for legacy and industrial boards needing robust electrolytic storage with defined endurance at elevated temperature.

Unique Advantages

• High Bulk Capacitance in Snap-in Form — 10 mF in a radial, snap-in can supports compact board layouts while providing significant energy storage.
• Designed for Audio Upgrades — Marketed specifically for audio equipment replacement to achieve perceived tone-quality improvements when upgrading from smaller standard parts.
• Strong Ripple Handling — 3.5 A ripple current rating at 120 Hz supports effective smoothing on rectified supplies typical in audio and power applications.
• Temperature and Endurance Specified — −40 °C to +85 °C operating range and 1000-hour life at 85 °C provide clear reliability expectations for design validation.
• RoHS Compliant — Meets current restricted-substance directives for use in regulated assemblies.
