Fixed inductors are an important component in modern power electronic circuits. MILS1812-684K are one of the most widely used fixed inductors. They offer high performance, reliability and temperature stability, making them ideal for harsh environments or applications where high power dissipation needs to be handled.

The MILS1812-684K is a high-performance, high-durability, and highly temperature stable, ceramic-core, wire-wound inductor, designed for use in a range of electronic applications, including automotive, power and signal line filtering, switch-mode power supplies, and audio-video equipment. It has a 1μH inductance with a DC resistance of 0.6 ohms. A separate lead is provided for mounting the inductor. The MILS1812-684K is capable of withstanding a high temperature range of -55°C to +150°C, making it suitable for use in challenging environmental and voltage conditions.

The MILS1812-684K provides excellent electrical performance, with low ACR, low drift, and low ESR at both low frequency and high frequency operation. It can handle both high frequency and high current pulses, with a high current capability of 10A. The inductor also maintains high efficiency, with high Q values for both high and low frequency ranges. At high frequencies, the inductance is unaffected, so the inductor can be used in frequency conversion applications.

The MILS 1812-684K’s construction ensures reliable operation in a variety of environmental conditions. It has been designed with a hermetically sealed epoxy potting to seal and protect the copper windings from moisture, dust, and other corrosive materials in the environment. The winding is also designed to provide optimal resistance to temperature-dependent inductance drift. In addition, the inductor has an internal magnetic shielding wall which provides protection from external magnetic fields.

The inductor’s working principle is simple: it works by creating a magnetic field in the vicinity of the inductor when current is applied. This magnetic field induces a change in the inductor’s inductance, which in turn induces a current in the inductor’s output. The output current will be equal to the product of the applied current and the inductance of the inductor. The voltage across the inductor is equal to the product of the applied current and the inductor’s resistance.

The MILS1812-684K is a highly reliable, highly temperature-stable, ceramic-core inductor suitable for a variety of fixed inductor applications in modern electronic circuits. It has a high current capability of 10A, which makes it suitable for high-power applications, while its hermetically sealed construction and internal magnetic shielding wall provide reliable operation and protection against external magnetic fields. Additionally, its low drift, low ESR, and high Q values make it ideal for high- and low-frequency applications. As such, the MILS1812-684K provides an ideal solution for a variety of fixed inductor applications.
