Fixed Inductors

The PT400R-1750-VM is a type of fixed inductor, an electrical component consisting of a coil of wire, designed to produce a magnetic field. Inductors are used in a wide range of applications, including power supplies, filters, and oscillators. Inductors are often found in the form of a component of a larger circuit, such as the one used in the PT400R-1750-VM\'s intended application.

Application Field

The PT400R-1750-VM is a radial-leaded, 10-ohm, 1mH (10mH) inductor designed for use in the Power over Ethernet (PoE) injector line. PoE is a technology that uses standard Ethernet cables to transfer both data and power. By assigning certain pairs of wires to carry power, PoE eliminates the need for additional power lines, allowing for simplified installations and reduced cost.

The PT400R-1750-VM inductor is specifically designed for PoE applications. Its radial-lead design allows it to fit easily into a tight installation space, while its 10-ohm-rated resistance allows for efficient operation over a wide temperature range (up to 60 degrees Celsius). Additionally, its 1mH inductance value has been carefully chosen to ensure optimal signal transmission and reduce power losses.

Working Principle

The PT400R-1750-VM, like all inductors, works by converting electrical energy into a magnetic field. The inductor is composed of a coil of wire, with one end connected to a power source and the other end connected to a return wire. When an electrical current passes through the coil, it creates a magnetic field. This magnetic field induces a current in the return wire, which is then sent back to the power source.

The PT400R-1750-VM is designed to perform this process efficiently. Its 1mH inductance means that it will create a strong enough magnetic field to induce a strong enough current in the return wire. Additionally, its 10-ohm resistance helps to ensure minimal power losses across the inductor, thus allowing the inductor to function more efficiently.

Conclusion

The PT400R-1750-VM is a radial-leaded, 10-ohm, 1mH inductor designed for use in PoE applications. Its radial-lead design allows it to fit easily into a tight installation space, while its 10-ohm-rated resistance allows for efficient operation over a wide temperature range. Additionally, its 1mH inductance value has been carefully chosen to ensure optimal signal transmission and reduce power losses. This makes the PT400R-1750-VM an ideal choice for PoE applications.
