LKSH2182MESY

The LKSH2182MESY is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series, designed for audio equipment and general-purpose applications. It provides 1.8 mF capacitance at a 71 V rated voltage in a compact, snap-in can package intended to improve tone quality when replacing a small standard product.

Built for installations requiring polarized bulk capacitance and robust ripple handling at low frequency, this component is RoHS compliant and suited to applications operating within −40°C to +85°C.

Key Features

• Capacitance & Voltage — 1.8 mF capacitance rated at 71 V, offering substantial bulk energy storage for power smoothing and decoupling in audio and general power circuits.
• Snap-in Radial Can Package — Snap-in terminal mounting for secure board retention and straightforward installation in chassis or PCB assemblies.
• Audio-focused Design — LKS-series wording indicates a smaller-sized part intended for audio equipment; documented as "smaller and high-tone quality than LKG TYPE-1 grade" and suitable for tone-quality improvement when replacing small standard parts.
• Operating Temperature Range — Rated for −40°C to +85°C, accommodating typical ambient ranges for consumer audio and general-purpose electronic equipment.
• Endurance & Lifetime — Specified endurance of 1000 hours at 85°C with defined limits for capacitance change, dissipation factor, and leakage current after the endurance test.
• Low-frequency Ripple Capability — Rated ripple current of 2 A at 120 Hz, suitable for smoothing low-frequency power rails in amplifiers and power supplies.
• Leakage Current Specification — Leakage defined per series specification: after 5 minutes at rated voltage and 20°C, leakage current is not more than 3√CV (μA), where C is μF and V is volts.
• Tolerance — Capacitance tolerance of −20% to +20% (±20% typical measurement basis at 120 Hz, 20°C).
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Bulk smoothing and power reservoir in audio amplifiers and preamplifiers, where the LKS series' smaller size and tone-quality characteristics can be beneficial.
• Power Supply Filtering — DC rail smoothing and decoupling on low-frequency power supplies that require polarized electrolytic bulk capacitance.
• General Purpose Electronics — Applications requiring polarized aluminum electrolytic capacitors with snap-in mounting for secure chassis or PCB integration.

Unique Advantages

• Compact, Snap-in Form — Radial snap-in can simplifies mechanical retention and serviceability compared with loose or adhesive-mounted capacitors.
• Audio-Optimized Series — LKS-series positioning and documented tone-quality improvement make this part a focused option when upgrading small standard components in audio signal chains.
• Defined Endurance — 1000 hours at 85°C endurance specification gives designers clear expectations for long-term performance under elevated temperature stress.
• Measured Ripple Rating — 2 A at 120 Hz ripple rating provides quantifiable capability for low-frequency smoothing tasks in power electronics.
• Clear Leakage Specification — Leakage current defined as 3√CV after 5 minutes at rated voltage (20°C) allows predictable behavior for bias and idle-current considerations.
• Regulatory Compliance — RoHS compliance supports deployments where restricted substances requirements apply.
