LKS1K102MESA

The LKS1K102MESA is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general-purpose power filtering. It delivers 1 mF capacitance at an 80 V rating in a compact snap-in radial can, offering designers a smaller-sized option intended to improve tone quality when used as a replacement for smaller standard parts.

Engineered for reliable operation across common operating conditions, the capacitor is RoHS compliant and specified for operation from −40 °C to +85 °C with a rated lifetime under load of 1000 hours at 85 °C.

Key Features

• Capacitance & Voltage: 1 mF (1000 μF) rated at 80 V DC with ±20% tolerance, suitable for higher-voltage smoothing and decoupling tasks within its rating.
• Snap-in Package: Radial, can-type snap-in mounting provides strong mechanical retention for robust PCB installation where panel hold-down is required.
• Audio-Focused Design: Marketed for audio equipment and noted for producing a tone-quality improvement when replacing smaller standard capacitors.
• Temperature Range & Endurance: Specified to operate from −40 °C to +85 °C and endurance rated at 1000 hours at 85 °C under applied rated voltage.
• Ripple Current Capability: Rated ripple current of 1.55 A at 120 Hz, enabling effective AC ripple handling at standard power-line frequencies.
• Leakage Current Specification: After 5 minutes at rated voltage and 20 °C, leakage current is specified as not more than 3√CV (μA), where C is rated capacitance (μF) and V is voltage (V).
• Polarized Design: Polar electrolytic construction suitable for DC power rails and filtering in polarized circuits.
• RoHS Compliance: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint: Physical size approximately L: 2.0 cm × D: 2.5 cm, offering a smaller-sized option within the LKS family.

Typical Applications

• Audio Equipment: Replacement and upgrade in amplifier and audio power-supply sections to improve tone quality and stabilize supply rails.
• Power Supply Filtering: Bulk smoothing and decoupling on DC rails where 1 mF at 80 V and 1.55 A ripple handling are appropriate.
• General-Purpose Electronics: Use in a wide range of consumer and professional electronics requiring polarized electrolytic capacitance with snap-in mounting.

Unique Advantages

• Designed for tone improvement: Market positioning and form factor target audible-performance gains when replacing smaller standard capacitors in audio products.
• Secure snap-in mounting: Snap-in radial can simplifies assembly and provides reliable PCB retention for through-hole designs.
• High-voltage capability in a compact body: 80 V rating combined with a small footprint enables higher-voltage filtering where board space is constrained.
• Measured ripple handling: 1.55 A at 120 Hz supports effective ripple attenuation in power-supply applications at mains-related frequencies.
• Operational reliability: Specified −40 °C to +85 °C range and 1000-hour endurance at 85 °C under rated voltage provide known performance bounds for design validation.
• Regulatory compliance: RoHS conformity supports use in products requiring restricted-substance compliance.
