This device is manufactured using ceramic ferrite technology and has a maximum DC resistance of 0.47 ohms. The device is rated at an operating temperature range between -40 to 85 degrees Celsius. Its electrical parameters include an inductance value of 33uH, a saturation current of 4.2A, and a nominal current of 11.5A.

Applications

The 12LRS334C is commonly used in power supplies for industrial machinery and automobiles, as well as in various audio equipment. It is also suitable for use in a variety of switching applications, such as motor control circuits. Additionally, the device can be employed in battery charger circuits to provide robust protection against high currents, as well as in applications that require low insertion losses.

Working Principle

The 12LRS334C is a fixed inductor that operates based on the principle of magnetic induction. This principle states that when a current passes through a coil of wire, it produces a magnetic field around the coil. This magnetic field strength is determined by the amount of current flowing through the coil, as well as the number of turns the coil contains.

In the case of the 12LRS334C, its core is made of dry air and its inductance value is determined by the number of turns that the coil contains. When current is applied to the coil, it produces a magnetic field around the core, which in turn induces a voltage in the winding. This voltage is then transferred to the output. The magnitude of this voltage is directly proportional to the amount of current flowing through the winding, as well as the inductance value of the coil.

Conclusion

The 12LRS334C is a fixed inductor type that is designed specifically for use in pulse width modulation applications. It is manufactured using ceramic ferrite technology and has a maximum DC resistance of 0.47 ohms. This device is commonly used in power supplies for industrial machinery and automobiles, as well as in various audio equipment. Its working principle is based on magnetic induction, where the current produces a magnetic field around the coil, which in turn induces a voltage in the winding.
