LKS1J103MESC

The LKS1J103MESC is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, optimized for audio equipment and general-purpose applications. It provides high capacitance in a compact radial, can-style snap-in package and is RoHS compliant.

With a capacitance of 10 mF and a rated voltage of 63 V, this polarized capacitor is intended for applications that require substantial energy storage, reliable ripple handling, and thermal endurance across a -40 °C to 85 °C operating range.

Key Features

• Electrical Capacity — 10 mF capacitance at a rated voltage of 63 V, offering significant energy storage for power smoothing and decoupling.
• Snap-in Radial Package — Snap-in mounting type with a radial can design for secure PCB retention and straightforward assembly.
• Audio-focused Design — Designed for audio equipment and described as smaller-sized with an intended effect of improving tone quality when used to replace small standard products.
• Operating Temperature & Endurance — Rated for -40 °C to 85 °C with a stated lifetime of 1000 hours at 85 °C; endurance criteria include capacitance change within ±20%, tan δ up to 200% of initial, and leakage current not exceeding initial specifications after the endurance test.
• Ripple Handling — Rated low-frequency ripple current of 4.4 A at 120 Hz to support power filtering demands in audio and general-purpose circuits.
• Tolerance & Polarization — Capacitance tolerance of -20% to +20% and polarized construction; leakage current specification follows the 3√(C·V) rule after initial application of rated voltage.
• RoHS Compliance — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.
• Physical Identification — Marked with silver lettering on a black sleeve for clear polarity and part identification.
• Compact Dimensions — Physical size approximately L: 4 × D: 3.5 cm, providing a compact footprint for higher-capacitance needs.

Typical Applications

• Audio Power Supplies — Bulk smoothing and energy storage for amplifier and preamplifier power rails where high capacitance supports stable audio performance.
• Audio Signal Equipment — Replacement upgrade in audio equipment to improve perceived tone quality compared with smaller standard capacitors.
• General-Purpose Power Filtering — Decoupling and ripple reduction in consumer and professional electronics within the stated temperature and lifetime limits.

Unique Advantages

• High Capacitance in a Compact Can — 10 mF at 63 V delivers substantial energy storage without requiring excessive board space.
• Audio-Oriented Performance — Specifically described for audio equipment with a design focus on improving tone quality when upgrading from smaller capacitors.
• Robust Thermal Endurance — Rated 1000 hours at 85 °C with defined endurance limits for capacitance, tan δ, and leakage current to support predictable long-term behavior.
• Strong Ripple Capability — 4.4 A ripple current rating at 120 Hz supports demanding power-filtering tasks in audio and general-purpose circuits.
• Secure Snap-in Mounting — Snap-in radial construction provides reliable mechanical retention for through-hole assemblies.
• Regulatory Compliance — RoHS-compliant construction for use in designs targeting restricted-substance requirements.
