Fixed inductors play an important role in the electronic application field as a component that stores energy in the form of a magnetic field. The SPD73-242M Inductor is a vertical mounted, shielded inductor series with a wide range of inductance values from .22uH to 1000uH, and is designed for general purpose, power line and EMI applications. This series is perfect for high power applications up to 70A with internal magnetic saturation protection.

The SPD73-242M series has an overall size of 2.42mm x 2.40mm, is lead free, and is RoHS compliant. It is ideal for use in cell phones, DC/DC converters, and has a wide operating temperature range of −40°C to +85°C.

SPD73-242M has two different types of common modes inductors which feature high energy storage capacity, a high common mode impedance, good temperature performance, low DC resistance, LL1608 package size, an inductance range from 0.22uH - 470uH, and operates from 400KHz to 2MHz.

The magnetically shielded SPD73-242M provides a high level of resistance to magnetic fields, providing it with the ability to suppress external interference and ensure high quality operation. It also provides a very wide and linear frequency response up to 1.2MHz.

The working principle of SPD73-242M inductors is based on the principles of electromagnetic induction. When current is applied to a conductor, a magnetic field is created. When the current reaches its steady state, a force is applied to the inductor which is proportional to the rate of change of the magnetic flux. This force then creates a voltage in the coil which opposes the current, thus limiting its rate of change.

The inductance of an inductor can be increased by adding more turns to the coil. This increases the impedance of the inductor which aids in improving the damping of the circuit. It also works with capacitors to form a low pass filter, allowing for the passage of lower frequency signals.

In addition to its use in analog applications, SPD73-242M is also suitable for digital applications. The tight tolerances provided by these inductors make them ideal for use in applications such as switching power supplies (SMPS) and digital signal processors (DSPs).

The SPD73-242M Inductor is a versatile component that is suitable for a wide range of applications from analog filters to digital signal processors. Its own characteristics provide excellent performance up to high frequencies, including power line EMI protection and a high current-carrying capacity.
