LKSN2222MESB

The LKSN2222MESB is a snap-in terminal aluminum electrolytic capacitor designed for audio equipment and general-purpose electronic applications. It delivers a 2.2 mF capacitance at a 56 V rating in a compact snap-in can intended for PCB mounting.

Engineered for tone-quality improvement when replacing smaller standard parts, this RoHS-compliant capacitor combines polarized aluminum electrolytic construction with a small footprint and durability for medium-duty filtering and smoothing tasks.

Key Features

• Electrical — Capacitance & Voltage: 2.2 mF nominal capacitance with a rated voltage of 56 V, suitable for a range of power and filtering functions.
• Tolerance: Capacitance tolerance ±20% (measured at 120 Hz, 20°C).
• Ripple Handling: Rated low-frequency ripple current of 1.85 A at 120 Hz, supporting power-supply smoothing and decoupling in audio and general-purpose circuits.
• Reliability & Lifetime: Endurance specified as 1000 hours at 85°C under rated voltage; after this test the capacitor meets the series endurance characteristics for capacitance, tan δ and leakage current.
• Temperature Range: Operating temperature range −40 to +85°C for use across broad environmental conditions.
• Mounting & Package: Snap-in terminal, radial can (snap-in) package for secure PCB assembly and straightforward replacement of similar snap-in parts.
• Physical Size: Compact dimensions — L: 2 × D: 3 cm — and a seated height of 2 cm, helping save board space in chassis-constrained designs.
• Polarization: Polarized electrolytic construction; observe polarity during installation.
• Leakage Current Specification: Leakage current after 5 minutes at 20°C is not more than 3√(C·V) μA (where C is rated capacitance in μF and V is voltage in V), per series specification.
• RoHS Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment: Used in audio amplifier and signal-chain power supplies for smoothing and filtering where replacement of smaller standard capacitors can improve perceived tone quality.
• Power Supply Filtering: Applied to bulk filtering and decoupling in general-purpose power supplies that require a 56 V-rated polarized capacitor with moderate ripple capability.
• Industrial & Consumer Electronics: Fits compact systems that need a snap-in radial electrolytic with a small footprint and reliable performance over −40 to +85°C.

Unique Advantages

• Compact, snap-in form factor: Small L × D footprint and snap-in mounting simplify board assembly and replacement of comparable snap-in capacitors.
• Tone-quality oriented design: Series-level design notes indicate improved tone quality when replacing small standard products, making it suitable for audio-focused applications.
• Measured ripple capability: 1.85 A at 120 Hz provides defined performance for low-frequency ripple environments and power smoothing tasks.
• Engineered endurance: Rated for 1000 hours at 85°C under rated voltage, supporting predictable life-cycle behavior in moderate-temperature applications.
• Clear leakage current spec: Leakage bounded by the 3√(C·V) μA formula after initial application of rated voltage, aiding design verification and margining.
• RoHS compliant: Meets applicable RoHS requirements, supporting regulatory and environmental objectives.
