LKSN2222MESY

The LKSN2222MESY from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LKS series, optimized for audio equipment and general‑purpose power applications. It provides 2.2 mF (2200 µF) capacitance at a 56 V rating in a compact φ20 × 30 mm radial, can‑style snap‑in package.

Designed for applications that require bulk energy storage and smoothing, the LKSN2222MESY delivers specified ripple handling and endurance across a −40 °C to +85 °C operating range, and is supplied in tray packing for PCB assembly.

Key Features

• Electrical Capacity — 2.2 mF (2200 µF) nominal capacitance with ±20% tolerance (measured at 120 Hz, 20 °C), rated for 56 V.
• Ripple Handling — Rated ripple current of 1.85 A at 120 Hz, suitable for AC ripple smoothing at the specified measurement frequency.
• Leakage Current — Specified leakage current of 1050 µA (after rated voltage application and standard test conditions).
• Mounting & Package — Snap‑in terminal, radial can (snap‑in) package for secure mechanical mounting and easy board insertion; supplied in tray packing.
• Operating Temperature — Specified range from −40 °C to +85 °C for operation across common ambient conditions.
• Endurance — Rated for 1000 hours at 85 °C with performance criteria for capacitance change, tan δ, and leakage current defined by the endurance test.
• Compliance — RoHS‑compliant material construction.

Typical Applications

• Audio Equipment — Intended for use in audio applications where the LKS series is specified; suitable for power supply smoothing and bulk decoupling in audio circuits.
• General‑Purpose Power Filtering — Bulk energy storage and ripple suppression in general electronic power supplies and consumer electronics.
• Replacement/Upgrade in Compact Designs — Smaller‑sized snap‑in option for designers replacing or upgrading existing radial electrolytic capacitors where φ20 × 30 mm fits the mechanical constraints.

Unique Advantages

• Compact snap‑in form factor — φ20 × 30 mm radial can with snap‑in terminals provides a small footprint for designs constrained by board space and height.
• High nominal capacitance at 56 V — 2200 µF enables significant bulk energy storage in higher‑voltage circuits without moving to larger packages.
• Defined ripple current rating — 1.85 A at 120 Hz gives a clear specification for AC ripple handling in power supply designs.
• Temperature and endurance specification — −40 °C to +85 °C operating range and 1000‑hour endurance at 85 °C provide predictable lifetime behavior under the stated conditions.
• RoHS compliant — Meets RoHS directive requirements for reduced hazardous substances.
• Tray packing — Supplied in tray packing to support handling and assembly processes for through‑hole/snap‑in components.
