LKSH2182MESZ

The LKSH2182MESZ is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series, engineered for audio equipment and general-purpose electronic designs. Its compact snap-in can and audio-focused design make it suitable as a replacement upgrade to small standard parts where improved tone quality is desired.

This polarized capacitor offers 1.8 mF capacitance at a 71 V rated voltage, RoHS compliance, and specification-backed endurance for reliable operation across a broad temperature range.

Key Features

• Electrical Performance — Capacitance: 1.8 mF with a tolerance of -20% to 20% and a rated voltage of 71 V, providing stable bulk energy storage for audio and general-purpose circuits.
• Audio-Focused Design — LKS series, snap-in terminal type marketed specifically for audio equipment; described as smaller-sized with an intended effect of tone quality improvement when replacing small standard products.
• Package & Mounting — Snap-in terminal, radial can package with a compact footprint (L: 3 × D: 2.2 cm), enabling secure board retention and simplified assembly for through-hole layouts.
• Thermal and Endurance Ratings — Operating temperature range of -40 °C to 85 °C and lifetime specification of 1000 hours at 85 °C under rated voltage.
• Ripple Handling — Rated ripple current: 2 A at 120 Hz, suitable for handling AC ripple in power and audio circuits within the specified rating.
• Polarized Construction — Polarized capacitor for DC circuit applications where polarity is defined and maintained.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Intended for use in audio-focused systems where replacing smaller standard capacitors can yield an observable improvement in tone quality.
• General-Purpose Electronics — Bulk energy storage and smoothing in a wide range of PCB-through-hole applications requiring a polarized aluminum electrolytic.
• Component Upgrades — Replacement/upgrading of existing small standard electrolytics to achieve improved audio characteristics in legacy or custom designs.

Unique Advantages

• Designed for audio tone improvement — The LKS series formulation and smaller-sized snap-in package are specified to provide a tonal upgrade when replacing small standard parts.
• Compact snap-in package — Radial, snap-in can with a small footprint (L: 3 × D: 2.2 cm) enables straightforward through-hole mounting and secure board attachment.
• High working voltage — 71 V rated voltage provides headroom for higher-voltage audio and general-purpose circuits within the part’s ratings.
• Ripple capability — 2 A ripple rating at 120 Hz supports handling AC ripple currents typical in power filtering applications.
• Thermal endurance — Rated for operation from -40 °C to 85 °C with a specified lifetime of 1000 hours at 85 °C, providing predictable performance in temperature-stressed environments.
• Regulatory compliance — RoHS-compliant construction supports environmentally conscious designs.
