LKS1K222MESY

The LKS1K222MESY is a snap‑in terminal aluminum electrolytic capacitor designed for audio equipment and general-purpose electronic applications. It provides a 2.2 mF capacitance at an 80 V rating in a radial, can-style snap‑in package.

This part targets designs where replacement of smaller standard capacitors can yield audible tone-quality improvements; it is RoHS compliant and built for operation across a broad temperature range.

Key Features

• Capacitance & Voltage – 2.2 mF nominal capacitance rated at 80 V DC; polarization is required (polar capacitor).
• Tolerance – Capacitance tolerance ±20% (measured at 120 Hz, 20°C).
• Audio-focused design – Snap‑in terminal type specified for audio equipment; the series notes an effect of tone-quality improvement when replacing smaller standard parts.
• Mounting & Package – Radial, can-style snap‑in package for secure PCB mounting.
• Operating Temperature & Endurance – Rated for operation from −40°C to +85°C with an endurance rating of 1000 hours at 85°C (after test, capacitance change within ±20%, tan δ ≤ 200% of initial specified value, leakage current ≤ initial specified value).
• Ripple Current – Rated ripple current of 2.45 A at 120 Hz, suitable for moderate ripple-handling applications.
• Leakage Current Specification – After 5 minutes at rated voltage and 20°C, leakage current is specified as not more than 3√(C·V) μA (where C is μF and V is volts), per the series specification.
• Dimensions – Physical size L: 4.5 × D: 2.0 cm (radial can, snap‑in).
• Environmental Compliance – Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Identification – Marked with silver color printing on a black sleeve.

Typical Applications

• Audio Equipment – Intended for use in audio signal chains and power stages where replacing smaller standard capacitors can improve perceived tone quality.
• General Purpose Electronics – Suitable for general-purpose smoothing and energy-storage roles in electronic power circuits within the specified temperature and voltage ratings.
• Component Upgrades – Used as a drop-in upgrade to small standard electrolytic capacitors to achieve improved performance characteristics noted in the LKS series documentation.

Unique Advantages

• Audio-oriented performance – The LKS series is specified for audio equipment and is documented to provide tone-quality improvement when replacing smaller standard products.
• High voltage rating – 80 V nominal rating provides headroom for higher DC applications within the series limits.
• Robust ripple capability – 2.45 A ripple rating at 120 Hz supports moderate ripple environments commonly found in power supply filtering.
• Durability at elevated temperature – 1000-hour endurance at 85°C with defined limits for capacitance change, dissipation factor, and leakage current.
• Secure snap‑in mounting – Radial snap‑in terminals provide mechanical retention suitable for upright PCB installations.
• Regulatory compliance – RoHS compliance ensures alignment with current restricted-substance requirements.
