LKS1E103MESB

The LKS1E103MESB is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, optimized for audio equipment and general-purpose applications. It delivers 10 mF (10,000 µF) capacitance at a 25 V rating in a compact, smaller-sized snap-in can package to support tone-quality improvements when replacing smaller standard parts.

Designed for board-level snap-in mounting, the LKS1E103MESB combines a compact footprint with defined ripple handling and thermal endurance for reliable performance across typical audio and general-purpose power filtering roles.

Key Features

• Capacitance & Voltage — 10 mF (10,000 µF) rated at 25 V for bulk energy storage and smoothing in low-voltage power rails.
• Snap-in Can Package — Radial, snap-in terminal mounting for secure board attachment and easy installation in chassis-mounted or PCB-adjacent filter banks.
• Compact Dimensions — Physical size: L 2.5 cm × D 3.0 cm (φD 30 × L 25 mm), enabling smaller, high-tone-quality designs.
• Ripple Current — Rated ripple current of 2.45 A (120 Hz) to support AC ripple filtering in power supply and audio circuits.
• Loss Characteristics — Specified tan δ of 0.30 (measurement at 120 Hz, 20°C) for predictable impedance and dissipation behavior.
• Operating Range & Endurance — Operating temperature −40°C to +85°C with endurance specified as 1000 hours at 85°C; after endurance test, capacitance change is within ±20% and leakage current remains within initial specification.
• Leakage Current Specification — Leakage current limited to not more than 3√(C·V) µA after 5 minutes’ application of rated voltage at 20°C (per datasheet formula).
• Polarized Electrolytic — Polarized design for DC filtering and energy-storage roles where correct polarity is observed.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment: Bulk filtering and power smoothing in amplifiers and audio signal chains where improved tone quality is desired by replacing smaller standard capacitors.
• Power Supply Filtering: DC link and reservoir capacitor for low-voltage supplies requiring 10 mF capacitance and defined ripple handling.
• General-Purpose Electronics: Energy storage and decoupling in industrial and consumer boards that accept snap-in mounting and require robust endurance at up to 85°C.

Unique Advantages

• Compact, Tone-Focused Design: Smaller-sized LKS construction targeted at audio applications provides a practical upgrade path from small standard parts to improve perceived tone quality.
• High Ripple Capability: 2.45 A ripple rating at 120 Hz supports effective smoothing in audio and low-voltage power supplies, improving regulator and amplifier stability.
• Defined Endurance: 1000-hour endurance at 85°C with validated post-test limits for capacitance, tan δ, and leakage current supports predictable life-cycle planning.
• Predictable Electrical Behavior: Specified tan δ and leakage current formula allow engineers to model dissipation and standby losses accurately.
• Snap-in Mounting for Secure Installation: Radial snap-in can provides firm mechanical retention for chassis and PCB layouts where vibration resistance and quick assembly are advantages.
• Regulatory Compliance: RoHS compliance supports use in designs targeting restricted-substance requirements.
