LKS1E103MESZ

The LKS1E103MESZ is an aluminum electrolytic capacitor in a snap-in radial can designed for audio equipment and general-purpose electronic use. It provides 10 mF (10,000 µF) capacitance at a 25 V rating in a compact 22 × 40 mm package.

Engineered for improved tone quality when replacing smaller standard capacitors, this Nichicon LKS series part combines a snap-in mounting style with a polarized design and RoHS compliance for straightforward integration into audio power and filter circuits.

Key Features

• Capacitance & Voltage – 10 mF (10,000 µF) rated at 25 V with ±20% tolerance for bulk energy storage and low-frequency filtering.
• Snap-in Radial Can Package – Snap-in terminal mounting for secure mechanical retention and quick installation on power assemblies and chassis-mounted boards.
• Compact Dimensions – 22 × 40 mm (φD × L) size providing a smaller footprint suitable for space-conscious audio designs.
• Ripple Current – Rated ripple current of 2.45 A (120 Hz), enabling effective smoothing in audio power supplies at mains frequency.
• Operating Temperature & Endurance – Specified for −40°C to +85°C with 1000 hours endurance at 85°C when rated voltage is applied, supporting stable performance over the specified life.
• Leakage Current Specification – Leakage current limited to not more than 3√CV (µA) after 5 minutes at 20°C, allowing predictable bias behavior in DC circuits.
• Tangent of Loss Angle (tan δ) – Specified tan δ of 0.30 (measured at 120 Hz, 20°C), indicating the dissipation characteristic for audio-frequency applications.
• Environmental Compliance – Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment – Bulk filtering and power smoothing in amplifiers and audio power supplies where replacing smaller capacitors can yield improved tone quality.
• Power Supply Reservoirs – Energy storage and ripple attenuation in general-purpose DC power circuits for consumer and professional electronics.
• Signal and Power Filtering – Low-frequency decoupling and smoothing in systems that require polarized electrolytic capacitors with higher capacitance.

Unique Advantages

• Tone-quality oriented design – Marketed specifically for audio equipment with a form factor intended to improve perceived tone when upgrading from smaller standard parts.
• High ripple handling – 2.45 A ripple current rating at 120 Hz supports effective mains-frequency smoothing in audio power stages.
• Predictable leakage behavior – Leakage current defined by the 3√CV formula ensures designers can budget bias currents accurately.
• Durability under rated stress – Endurance specification of 1000 hours at 85°C under rated voltage offers a quantifiable life expectancy for thermal-stressed designs.
• Compact snap-in package – Radial, snap-in construction simplifies assembly and provides reliable mechanical retention for chassis or PCB-mounted power modules.
• RoHS compliant – Meets current RoHS requirements for easier regulatory compliance in end products.
