Additional Details

Based on similar Walsin chip inductors, the SF04T2211BCL likely has an inductance value of 220nH (221), with the 'SF04T' likely indicating the case size and series. The 'BCL' might denote specific electrical characteristics or packaging. Multilayer chip inductors are constructed by stacking multiple layers of ceramic material with conductive patterns, creating a compact and efficient inductor.

Key specifications for the SF04T2211BCL would include the inductance value (220nH), tolerance (e.g., ±5%), self-resonant frequency (SRF), DC resistance (DCR), and rated current. The SRF is the frequency at which the inductor's impedance is at its maximum. The DCR is the resistance of the inductor's winding. The rated current is the maximum current that the inductor can safely handle. The Q-factor is a measure of the inductor's efficiency. A higher Q-factor indicates lower losses. Chip inductors are typically available in various case sizes, such as 0402, 0603, and 0805. Walsin Technology Corporation is a leading manufacturer of passive components, and their chip inductors are widely used in various electronic devices. Consult the datasheet for precise specifications, including the inductance value, tolerance, SRF, DCR, and rated current. Proper soldering techniques should be used when mounting the chip inductor to ensure reliable connections. The operating temperature range is typically -55°C to +125°C.
