The 0805CS221XKLC is a wirewound chip inductor manufactured by Coilcraft. Chip inductors are passive components used in electronic circuits to store energy in a magnetic field when electric current flows through them. They are commonly used for filtering, impedance matching, and tuning circuits. This specific inductor comes in a standard 0805 surface-mount package, indicating its physical dimensions.

Applications

• RF Filters: Used in radio frequency circuits to block unwanted frequencies and allow desired signals to pass.
• Impedance Matching: Employed to match the impedance of different circuit sections to maximize power transfer.
• Oscillator Circuits: Integrated in oscillators to determine the frequency of oscillation.
• Power Supplies: Utilized in power supplies for filtering and energy storage.
• Wireless Communication Devices: Found in smartphones, tablets, and other wireless devices for signal conditioning.

Features

• Inductance: 220 nH (nanohenries). This value determines the inductor's ability to store energy in a magnetic field.
• Tolerance: ±10%. The actual inductance value may vary by up to 10% from the nominal value.
• Self-Resonant Frequency (SRF): High SRF, typically in the hundreds of MHz. This is the frequency at which the inductor's impedance becomes predominantly resistive.
• DC Resistance (DCR): Low DCR. This minimizes power loss due to the inductor's internal resistance.
• Package: 0805 surface-mount package. This is a standard package size that is easy to handle and solder using automated assembly equipment.

Benefits

• Compact Size: The 0805 package allows for high-density circuit designs, saving valuable board space.
• High Performance: The wirewound construction provides high Q factors and low DCR, resulting in efficient energy storage and low losses.
• Reliable Operation: Coilcraft inductors are known for their robust construction and reliable performance.
• Easy to Assemble: The surface-mount package is compatible with automated assembly equipment, reducing manufacturing costs.
