Fixed inductors are components with a coil of wire having one fixed end and a capacitor used for modulation of signals in electronic circuits. The MILS1812R-274K, a fixed inductor from EPCOS, is designed for electrical applications including power supplies, dc-dc converters, and automotive electronics. This inductor has been designed with the aim of providing high insulation and high power output for various types of high-voltage and high-current components.

The MILS1812R-274K has a maximum direct current rating of 4.5 Amps. It has an inductance of 27.4 uH and a saturation current of 9.0 Amps. Its impedance at 10 kHz is 5.2 Ohms, while its series resistance is 0.015 Ohms. Its capacitance is 0.45 nF and its self-resonance frequency is 2.1 MHz. Additionally, the peak current for which it is designed is 1.3 Amps.

The MILS1812R-274K has a variety of applications, including automotive power management, DC-DC converters, high-speed switching power supplies, and other power system applications. Its inductance and low resistance make it suitable for use in DC-DC converter circuits that need to reduce the voltage for output voltage stabilization.

The working principle of the MILS1812R-274K is based on Faraday\'s law which states that when an electric current passes through a coil of wire, an external magnetic field is created. When this field is coupled with the current in the coil, it produces a magnetic flux, which is captured in the form of inductance. This inductance can be used to modify an electrical signal or control power transfer in an electronic circuit.

The MILS1812R-274K\'s insulation is based on two ceramic cores and an epoxy body. The two ceramic cores serve as traps for the induced current flow when current flow is expected. The epoxy body surround the ceramic cores and prevents any external magnetic forces from entering and interfering the circuit. The inductor features a curved edge layer that reduces electromagnetic interference.

The MILS1812R-274K is a robust inductor that is suitable for many high-power applications. With its high insulation properties and ability to control power transfer, it is an ideal choice for many kinds of applications, including power management, DC-DC converters, high-speed switching power supplies, and other power system applications. It is also reliable and durable enough for various automotive needs, making it an excellent choice for many modern applications.
