Fixed Inductors are electrical components which are used to store energy in the form of a magnetic field. The basic function of a fixed inductor is to introduce a certain amount of inductance into a circuit to help regulate frequency and reduce transient voltage spikes. The PT75-1550HM is a fixed inductor capable of withstanding high voltages and temperature fluctuations, commonly used in a variety of applications including power supplies and motor control.

The PT75-1550HM is a 15 millihenry (mH) fixed inductor rated for 75 volts and 10 amps of current. This inductor has an operating frequency range of 100 - 500 KHz, allowing for a variety of circuit topologies in which to use the device. This device is composed of a ferrite core and wire coil combination, creating the necessary inductance in the circuit. The ferrite core is also designed to be temperature stable and to resist thermal fatigue.

One of the most common and easy-to-implement applications of the PT75-1550HM is for voltage regulation in power supplies. The inductor helps reduce line-level voltage transients, thus increasing the accuracy of the output voltage. This can be seen in a typical buck transformer circuit, where the inductor helps to control the capacitor’s discharge time, and hence the output voltage waveform. Other applications of the device include use as input for motor control circuits, such as three-phase bridge rectifier circuits or for inverters.

The PT75-1550HM also finds application in high frequency switching circuits. In such circuits, the device is used to create the necessary inductance forFilter circuits, RFID or NFC antennas, or power induction charging where the device has to be tightly coupled to the circuit. The PT75-1550HM is designed for use with high frequency switching signals between 100 KHz and 500 KHz and can absorb high surge currents of 10A.

The inductor’s core material, ferrite, is designed for high temperature stability over the operating temperature range of -20°C to +105°C, making it suitable for automotive and consumer applications. The device also has a high insulation resistance value of 30 Megaohms (M ohms), which ensures there is no premature electrical breakdown due to electrostatic charging. In addition, the low DC resistance value of the device enables it to be used to carry high current while still meeting insulation requirements.

In conclusion, the PT75-1550HM is a high performance fixed inductor that is well-suited to various commercial and industrial applications. It is available in an economical surface mount design and easily integrates into production line printed circuit boards. The device offers good thermal and voltage stability, high insulation resistance, low DC resistance, and temperature operation for waves up to 500 KHz.
