Fixed inductors provide a stable inductance against operating temperature and current. The 18R684C is a segmented wirewound inductor used for a variety of high power applications. This inductor is capable of operating up to 15 A of current, with a maximum inductance of 24 μH. With a tolerance of ±30%, the 18R684C is suitable for RF applications, automotive power supplies, and intermediate power range applications.

The construction of the 18R684C consists of a segmented wirewound inductor encapsulated with resin. This resin encapsulation appears either in resin-molded or bobbin-style. The bobbin style is easier to mount due to its smaller size. Bobbin-style inductors can also take up much higher load currents than resin-mold type inductors.

The 18R684C has a self-supporting coil with low internal resistance. The metal-oxide varistor has an insulation system that is capable of withstanding a high peak current up to 100 A. This ensures stable performance and better protection from electric arcs. The 18R684C offers excellent temperature stability and high inductance. It is also resistant to corrosion and is encapsulated in a strong and durable material.

The working principle of the 18R684C is essentially the same as that of other inductors. When a current flows through the inductor, it stores energy in the form of a magnetic field. This stored energy acts as a counteracting force to opposite changes in current. Thus, when the applied voltage changes, the stored energy strengthens the inductance and increases its impedance, which reduces the rate of change in current. The inductance of a unit of the 18R684C is constant regardless of the value of the current.

The 18R684C is commonly used in DC-DC converters, switching power supplies, UPS systems, and automotive power supplies. Its high inductance and stable performance makes it suitable for applications where the inductance needs to be constant over a wide range of temperatures and currents. Its high peak current rating of 100 A makes it suitable for a wide range of high power applications.

The 18R684C is capable of handling a large variety of inductance related applications, from RF to power supplies. Its high peak current rating and temperature stability make it suitable for high power and intermediate power range applications. With its excellent performance and robust construction, the 18R684C is a reliable and efficient inductor choice for high power applications.
