LKS1H123MESB

The LKS1H123MESB is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series designed for audio equipment and general-purpose electronic circuits. It delivers 12 mF (12,000 µF) capacitance at a 50 V rating in a compact, smaller-sized snap-in radial can package.

Engineered for applications that benefit from improved tonal characteristics when replacing smaller standard capacitors, this RoHS‑compliant component offers a defined operating range, verified endurance, and a specified ripple-current capability for demanding low-frequency environments.

Key Features

• Capacitance & Voltage — 12 mF (12,000 µF) nominal capacitance with a 50 V rated voltage and tolerance of ±20% (−20% to +20%).
• Snap-in Radial Can Package — Snap-in mounting type and radial can construction for secure PCB retention and rugged mechanical installation.
• Audio-oriented, Smaller-sized — Marketed for audio equipment with a stated tonal improvement when replacing from smaller standard products.
• Operating Temperature & Endurance — Rated for −40 °C to +85 °C. Endurance specified as 1000 hours at 85 °C with capacitance change within ±20%, tan δ within 200% of initial specified value, and leakage current meeting initial limits after the test.
• Ripple Current Capability — Low-frequency ripple current rating of 4.2 A at 120 Hz, suitable for applications with significant AC ripple at that frequency.
• Leakage Current Specification — Leakage current is specified as not more than 3√CV (µA) after 5 minutes’ application of rated voltage at 20 °C (C = rated capacitance in µF, V = voltage in V).
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size — Compact footprint with dimensions listed as approximately L: 5 × D: 3 cm in product data.

Typical Applications

• Audio Equipment — Used in audio systems where replacing smaller standard capacitors can yield measurable tonal improvements.
• General-purpose Electronic Circuits — Suitable wherever a polarized, high-capacitance snap-in capacitor (12 mF, 50 V) is required in a compact radial can package.
• Power Filtering in Low‑Frequency Systems — Applicable in designs that require rated ripple-current handling at 120 Hz.

Unique Advantages

• Tonal improvement for audio designs: Specifically described for audio equipment, the part is intended to provide an effect on tone quality when used to replace smaller standard capacitors.
• High ripple capability: 4.2 A ripple current rating at 120 Hz reduces thermal and electrical stress in low-frequency ripple environments.
• Defined endurance performance: Specified 1000-hour endurance at 85 °C with quantified limits for capacitance, tan δ, and leakage current to support long-term design planning.
• Predictable leakage behavior: Leakage current limit of 3√CV (µA) after 5 minutes at 20 °C provides an explicit verification metric for designers.
• RoHS compliance: Meets RoHS (2011/65/EU, (EU)2015/863) requirements for restricted substances.
• Secure mounting: Snap-in radial can construction provides mechanical stability for through‑hole PCB installations.

Why Choose LKS1H123MESB?

As part of Nichicon's LKS series, the LKS1H123MESB balances audio‑oriented performance and general-purpose utility in a smaller snap-in aluminum electrolytic package. Its combination of 12 mF capacitance at 50 V, a 4.2 A ripple rating at 120 Hz, and a defined 1000‑hour endurance at 85 °C makes it suitable for designers seeking a reliable, RoHS‑compliant polarized capacitor for audio and broader PCB applications.

This capacitor is ideal for engineers specifying replacement or upgrade components in audio chains and for those requiring clear, testable electrical limits (leakage current formula, endurance criteria) to support robust design validation and lifecycle planning.
