Introduction

PT250R-1200HM is a type of inductor, notably a fixed inductor, in the form factor of a disk or cylinder. The inductor is suitable for applications in power line filters, electronic ballast, DC-DC converters, SMD transformers and automotive circuits. The inductor features flat films, voltage rating of 2KV, temperatures from -40 to 125⁰C, and low DC resistance.

Application Field

The range of applications for the PT250R-1200HM fixed inductor is broad and includes power line filters, electronic ballast, DC-DC converters, SMD transformers, and automotive circuits. In power line filters, the inductor is used to provide electromagnetic interference (EMI) attenuation and ripple noise filtering. Electronic ballast utilizes the inductor’s flat film construction to create compact designs with low losses. DC-DC converters require the inductor’s low DC resistance to ensure efficient conversion. The wide temperature range found in the inductor’s construction allows it to be used in automotive circuits, providing a reliable, fail-safe component in the process.

Working Principle

The principle behind the PT250R-1200HM fixed inductor is that of inductance. When current passes through an inductor, an opposing magnetic field is produced. This is known as reactive power, and it opposes the initial current, causing a voltage drop. This voltage drop is the inductor’s inductance, measured in henries (H). A higher inductance signifies greater voltage drop for the same amount of current. As such, the PT250R-1200HM offers high inductance and low DC resistance, providing the ideal inductance component for power line filters, electronic ballast, DC-DC converters, SMD transformers, and automotive circuits.

Conclusion

In conclusion, PT250R-1200HM fixed inductors offer a range of features that make them suitable for a variety of applications. These include power line filters, electronic ballast, DC-DC converters, SMD transformers, and automotive circuits. Furthermore, the inductor works on the principle of inductance, wherein a magnetic field impedes the current’s flow, thus producing a voltage drop. This voltage drop is the inductance that is measured in henries (H). The higher the inductance, the greater the voltage drop for the same amount of current. Its construction consists of flat films, 2KV voltage rating, temperatures from -40 to 125⁰C, and low DC resistance, making it an ideal component for the aforementioned applications.
