LKS2A821MESZ

The LKS2A821MESZ is an aluminum electrolytic capacitor in Nichicon's LKS series featuring a snap-in terminal radial can designed for audio equipment and general-purpose electronic assemblies. Its smaller-sized snap-in package and specifications are intended for applications where upgrading from small standard capacitors can deliver measurable tone-quality improvements.

Key electrical characteristics include 820 µF capacitance, 100 V rated voltage, polarized construction, and RoHS compliance. The part is specified for operation from -40 °C to 85 °C with an endurance rating of 1000 hours at 85 °C.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 100 V rated voltage, suitable where higher voltage headroom is required.
• Tolerance — ±20% capacitance tolerance at 120 Hz, 20 °C.
• Package & Mounting — Radial can with snap-in terminals for secure panel or chassis mounting in assemblies that accept snap-in style capacitors; smaller-sized footprint (L: 2.5 × D: 2.2 cm).
• Audio-focused Performance — Specified as "for audio equipment" and noted for tone-quality improvement when replacing smaller standard products.
• Temperature & Lifetime — Operating range −40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C.
• Ripple Handling — Rated ripple current of 1.75 A at 120 Hz, supporting typical low-frequency ripple conditions indicated in the datasheet.
• Polarized Design — Polar capacitor construction for correct polarity installation in DC circuits.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Used in audio assemblies where upgrading from smaller standard capacitors can improve tone quality.
• General-Purpose Electronics — Suitable for general-purpose electronic designs that require a snap-in aluminum electrolytic capacitor with moderate ripple capability and high voltage rating.
• Snap-in Mount Assemblies — Fits chassis or PC board layouts designed for snap-in radial can capacitors where a compact footprint and secure mounting are needed.

Unique Advantages

• Designed for Audio Upgrades — Marketed specifically for audio equipment with noted tone-quality improvement when replacing smaller standard capacitors.
• High Voltage Rating — 100 V rating provides voltage margin for applications requiring higher working voltages.
• Compact Snap-in Form Factor — Smaller-sized radial can with snap-in terminals enables space-conscious designs while maintaining secure mechanical attachment.
• Validated Endurance — Endurance specified at 1000 hours at 85 °C, with defined limits for capacitance change, tan δ, and leakage after the endurance test.
• Measurable Ripple Capability — Rated ripple current of 1.75 A at 120 Hz, useful for designs with low-frequency ripple demands.
• Regulatory Compliance — RoHS compliance aligns with environmental requirements for many commercial electronics projects.
