Fixed Inductors are common in many electronic applications. The P1330-273J is one such device - a surface mount inductor in a leadless package. It is designed to provide high currents (at low operating frequencies) for multiple functions, including RF power delivery, filtering, and balancing.

The P1330-273J is based on a ceramic structure with an iron core. The ceramic body is encased in an epoxy material to provide isolation from the environment and create a reference plane. The core material is a combination of ferrite and iron powder, which allows the device to handle power up to about 20 Watts.

The main feature of the P1330-273J is its high power density. It can operate in temperatures up to 75°C without the need for external heat dissipators, and its power handling extends up to 20 Watts. Despite its high power rating, the inductor has a very small surface footprint which makes it ideal for design in applications with restricted space.

The device is rated for a nominal inductance of 270nH, with a range of +-10%, at a frequency range from 0.1 to 500MHz. The direct current wire test was measured at 12 Amps, and the saturation current at 6 Amps. Being a surface mount component, the device uses a single bottom-connected flat-top contact pad, which allows it to be easily soldered to a PCB with no additional soldering.

The working principle of the P1330-273J is based on Faraday’s law of induction. When an AC voltage is applied to the device, a magnetic flux will be generated which will link with the inductor’s ferromagnetic core, inducing an electromotive force in each turn of the inductor winding. This will cause the inductor to absorb energy from the source, storing it in its magnetic field. This stored energy then dissipates back to the source when the AC voltage is removed from the device.

The P1330-273J is suitable for a variety of applications, including RF power delivery, filtering, clocks, power supplies, balancing, motor drivers, and impedance matching. The device is also ideal for use in Switch Mode Power Supplies, DC-DC converters, and high frequency/voltage regulation circuits.
