Fixed inductors are a type of passive electrical component which operate based on the principle of electromagnetic induction. Generally, inductors store and release energy through a magnetic field which is generated when electrical current is applied. Fixed inductors can be used to provide a range of functions such as filtering out high-frequency signals, providing impedance matching, and transformer isolation.

The PM1038S-R75M-RC fixed inductor is a polyester-film, axial-lead, radial-leaded SMD inductor. Its applications include RF, VHF, TV stereo, HF and VLF coils. The main specifications of the device are the inductance value, DC resistance, quality factor, and dissipation factor. The rated operating temperature range of the inductor is from -40°C to 105°C.

This particular inductor is characterized by its robust construction which ensures high mechanical, electrical and environmental reliability. The built-in substrate of the device ensures improved thermal and mechanical performance and low temperature rise. The inductor has an exceptional flash over voltage and excellent solderability. It provides superior EMC performance in the presence of moisture and can withstand mechanical shock, vibration and temperature cycling.

In terms of the principles of operation, when the device is used in an electromagnetic field, the core of the inductor stores energy in the form of magnetic flux. This flux is then released when the current is removed. This creates an inductive current flow which is proportional to the time-varying rate of change of the flux. The inductor also exhibits high self-resonant frequency and low DC resistance.

In addition to providing high current capacity and withstanding mechanical shock and vibration, the PM1038S-R75M-RC fixed inductor features excellent self-resonant frequency of up to 150MHz, high current capacity and low temperature rise. It also provides superior EMC performance and quick response time. The tuned circuit of the device provides for anti-oscillation at a wide frequency range.

The PM1038S-R75M-RC is an ideal choice for RF, VHF and TV stereo coils. It is suited for applications where the inductors are required to operate within the temperature range of -40°C to 105°C and withstanding the mechanical shock, vibration and temperature cycling. Moreover, the device exhibits high current capacity and low DC resistance along with superior EMC performance and quick response time.
