LKS1H272MESB

The LKS1H272MESB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general‑purpose electronic applications. It delivers 2.7 mF capacitance at a 50 V rating in a compact radial can with snap‑in mounting, offering a smaller footprint and a tone‑quality improvement when used as a replacement for smaller standard parts.

Engineered for reliable operation from -40 °C to 85 °C, the capacitor is RoHS‑compliant and provides defined endurance and ripple handling for demanding audio and general power‑filtering roles.

Key Features

• Capacitance & Voltage — 2.7 mF nominal capacitance rated at 50 V with a tolerance of ±20% (measured at 120 Hz, 20 °C).
• Snap‑in Radial Can — Snap‑in terminal type for robust vertical mounting and secure PCB retention in power and audio assemblies.
• Compact Dimensions — Package size approximately L: 2 cm × D: 3 cm with a seated height up to 2 cm, suitable for space‑constrained designs.
• Operating Temperature & Endurance — Rated for -40 °C to 85 °C with a stated lifetime of 1000 hours at 85 °C; endurance conditions specify capacitance change within ±20% after test.
• Ripple Current Capability — Rated low‑frequency ripple current of 1.9 A at 120 Hz, suitable for smoothing and filtering in audio power paths.
• Leakage and Loss Characteristics — Leakage current specified as not more than 3√(C·V) μA after 5 minutes at 20 °C; tangent of loss angle (tan δ) specified per datasheet test conditions.
• Polarized Device — Polar capacitor construction for DC supply decoupling and smoothing applications.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Replacement or upgrade use to improve tone quality and smoothing in audio amplifier and signal power circuits.
• General‑Purpose Power Filtering — Bulk and decoupling capacitance in power supply rails for a wide range of electronic devices.
• Board‑Level Snap‑in Installations — Applications requiring secure vertical mounting and easy insertion on PCBs where radial snap‑in packages are preferred.

Unique Advantages

• Compact, serviceable form factor: Small radial can and snap‑in terminals minimize PCB footprint while enabling straightforward board assembly.
• Audio‑oriented performance: Described as delivering a tone‑quality improvement when used as a replacement for smaller standard parts, making it attractive for audio designers.
• Defined endurance and reliability: Endurance specification of 1000 hours at 85 °C with limits on capacitance change, tan δ, and leakage current provides predictable long‑term behavior.
• Clear electrical specs: 2.7 mF at 50 V, ±20% tolerance, and a quantified low‑frequency ripple current rating (1.9 A at 120 Hz) support accurate design calculations.
• RoHS compliance: Meets applicable RoHS directives for environmentally regulated designs.
