Fixed Inductors

A Fixed Inductor (or choke, in the older nomenclature) is an electronic component which behaves like a resistor at constant current and has an inductive effect at AC. This makes inductors indispensable components for filtering, tuning circuits, and similar applications requiring electromagnetic properties. In the electronics industry, one of the most commonly found Fixed Inductors is the PM7032S-150M.

PM7032S-150M Application Field and Working Principle

The PM7032S-150M is a surface-mounted Fixed Inductor which is designed for use in a variety of DC-DC power conversion and other power applications. The PM7032S-150M is an excellent choice for applications requiring good frequency control, such as DC-DC buck and boost converters, digital power supplies, and power transducers. It also works well in converter grounding applications.

In terms of its working principle, the PM7032S-150M functions as an inductor, blocking and resisting any changes in current that try to pass through it. Inductors possess the unique characteristic of being able to resist changes in current flow through them, and so, when connected to an AC source, they will act as if they were a resistor. This makes them perfect for filtering and preventing unwanted transient signals from entering a circuit, or for providing stability to circuits by absorbing switching noise from power supplies.

The PM7032S-150M is designed with a saturation current rating of 150mA, a resistance of 1.2Ω, an inductance of 2.2uH, and a DC resistance of 0.04Ω. This makes it an ideal choice for low voltage, low dropout applications such as power banks, USB chargers, and similar applications. Additionally, it features a low temperature coefficient and a high quality factor (Q-factor), which is a measure of the efficiency of the component and helps to ensure reliable operation.

The PM7032S- 150M is also notable for its low profile design, which makes it ideal for use in embedded systems or space-constrained designs. It is also RoHS compliant, complete with a lead-free pure tin finish. Finally, the component is rated for -40°C to +85°C operating temperatures as well as 1000 hours of durability.

Conclusion

Fixed Inductors are indispensable components in the electronics industry, and the PM7032S-150M is a prime example of the technology at the forefront. Designed with a high quality factor and low DC resistance, the component is perfect for low voltage and low dropout applications. The low profile and RoHS compliant design also make the PM7032S-150M an ideal choice for embedded systems and space-constrained designs. With its high durability and operating temperature range, it is sure to offer reliable performance in whatever application it is used for.
