LKS2A821MESY

The LKS2A821MESY is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LKS series, designed for audio equipment and general‑purpose applications. It is a smaller‑sized, polarized can capacitor intended to deliver an effect of tone quality improvement when replacing a small standard product.

Key attributes include 820 µF nominal capacitance, 100 V rated voltage, snap‑in radial can packaging, RoHS compliance, and an operating temperature range of −40 °C to +85 °C.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 100 V rated voltage; capacitance tolerance is ±20% (measured at 120 Hz, 20 °C).
• Package & Mounting — Snap‑in terminal type in a radial can package for vertical board installation and secure mechanical retention.
• Audio‑Oriented Design — LKS smaller‑sized grade specifically noted for an effect to tone quality improvement when used as a replacement for small standard products in audio equipment.
• Operating Temperature & Endurance — Rated for −40 °C to +85 °C with an endurance specification of 1000 hours at 85 °C under rated voltage; after endurance the part meets defined limits for capacitance change, tan δ, and leakage current.
• Electrical Performance — Rated ripple current of 1.75 A at 120 Hz (low frequency), and leakage current specified as not more than 3√CV (µA) after 5 minutes at 20 °C.
• Polarized — Polar electrolytic construction for DC applications requiring bulk capacitance.
• Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size — Compact footprint with approximate dimensions L: 3 cm × D: 2 cm suited to space‑constrained board layouts.

Typical Applications

• Audio equipment — Intended use in audio designs where replacing a smaller standard capacitor can contribute to perceived tone quality improvement.
• General‑purpose electronics — Suited for designs that require a polarized, snap‑in aluminum electrolytic capacitor rated at 820 µF and 100 V within a −40 °C to +85 °C operating range.
• OEM assemblies — Use in assembled modules or systems that need vertical, snap‑in capacitors for board mounting and reliability under elevated temperature endurance conditions.

Unique Advantages

• Designed for audio improvement: The LKS series' smaller‑sized grade is described as providing an effect to tone quality improvement when replacing small standard products.
• High voltage capability: 100 V rating allows use in higher‑voltage circuits that require substantial capacitance.
• Defined endurance performance: Specified endurance of 1000 hours at 85 °C with clear limits on capacitance change, tan δ, and leakage current supports design predictability.
• Secure snap‑in mounting: Snap‑in terminal and radial can packaging provide mechanical retention for vertical board installation.
• Measurable ripple handling: Rated ripple current of 1.75 A at 120 Hz supports designs where low‑frequency ripple capability is specified.
• RoHS compliant: Constructed to meet RoHS directive requirements (2011/65/EU, (EU)2015/863).
