LKSN2822MESB

The LKSN2822MESB is an aluminum electrolytic, snap-in terminal capacitor from Nichicon’s LKS series designed for audio equipment and general-purpose use. It combines a compact snap-in radial can package with high capacitance to support power filtering and decoupling in chassis-mounted designs.

This part is polarized and RoHS compliant, offering a rated voltage of 56 V, capacitance of 8.2 mF (8200 μF), and an operating temperature range of −40 °C to +85 °C for reliable performance across typical ambient conditions.

Key Features

• Capacitance & Voltage: 8.2 mF (8200 μF) at 56 V rated provides substantial bulk energy storage for filtering and smoothing tasks in power circuits.
• Snap-in Radial Can Package: Radial, can-type snap-in mounting simplifies chassis and board mounting for secure mechanical and electrical connection.
• Operating Temperature Range: −40 °C to +85 °C, suitable for a wide range of ambient conditions encountered in audio and general-purpose equipment.
• Ripple Current Capability: Rated ripple current of 3.8 A at 120 Hz (low frequency), supporting applications with moderate AC ripple on DC rails.
• Polarized Electrolytic: Polarized construction for use where electrolytic capacitors are required.
• Tolerance and Loss: Capacitance tolerance ±20% and specified tan δ characteristics per datasheet measurement conditions.
• Endurance: Specified for 1000 hours at 85 °C with defined limits for capacitance change, tan δ, and leakage current after endurance testing.
• RoHS Compliant: Meets RoHS directive requirements for restricted substances.
• Physical Size: Compact footprint with dimensions approximately L: 4.5 × D: 3 cm for layouts with limited space.
• Leakage Current Specification: After 5 minutes at rated voltage and 20 °C, leakage current is specified as not more than 3√CV (μA), where C is μF and V is volts.

Typical Applications

• Audio Equipment — Designed for use in audio systems where replacement from smaller standard parts can yield audible tone quality improvements as noted for the LKS series.
• General-Purpose Power Circuits — Bulk smoothing and decoupling in chassis-mounted or board-mounted power supplies and filter stages.
• Equipment Upgrades / Replacements — Intended as a smaller-sized alternative within the LKS family for replacing compact standard capacitors to improve circuit performance.

Unique Advantages

• High Bulk Capacitance: 8.2 mF (8200 μF) enables effective energy buffering and ripple reduction in power rails.
• Snap-in Mounting: Provides robust mechanical retention and straightforward assembly for chassis- or board-mounted applications.
• Designed for Audio Systems: Part of the LKS series noted for smaller size and tonal improvements when replacing small standard products, making it suitable for audio-focused designs.
• Specified Endurance: 1000 hours at 85 °C with defined acceptance criteria for capacitance, tan δ, and leakage current supports predictable long-term behavior.
• Measured Ripple Handling: 3.8 A at 120 Hz rating gives a quantified basis for thermal and ripple budgeting in design.
• Regulatory Compliance: RoHS compliance supports deployment in regions and products requiring restricted-substance conformance.
