Fixed inductors are electrical components designed to create DC or AC electromagnetic fields. The inductors come in various shapes and sizes, such as flat wire coils, flat-film coils, and cylindrical coils. They are typically constructed with coiled wire wound over a core material, such as ferrite or iron. The material used to form the core determines the inductance, which is the measure of an inductors’ ability to oppose changes in electric current. A higher inductance means that the inductors can produce a stronger magnetic field.

The PTHF100R-40SM is a type of fixed inductor that is designed to provide high efficiency and performance in a compact package. It is particularly well-suited for use in applications involving high current signal applications, where precision impedance control, high-Q performance, and accurate linearity are required. The PTHF100R-40SM has a total size of 40mm and is composed of a core of ferrite and a wire-wound coil. It also features excellent soldering resistance and is compliant with RoHS and REACH standards.

The PTHF100R-40SM is primarily used for RF power amplifiers and communication products such as Wi-Fi, Bluetooth, and other digital signal relays. It is also used for broadband communication, RF front-end, analog-to-digital converter (ADC) components, and for DC-DC converters. The inductors provide a high-inductance rating, making them suitable for higher current applications while also providing frequency accuracy.

The working principle of the PTHF100R-40SM is based on the concept of inductance. As current passes through the inductor, it produces a magnetic field around a core material. This magnetic field opposes any changes in electrical current that might occur, allowing for precise control of the current flow rate. The inductors’ impedance decreases as the frequency of the signal being passed through it increases, making it ideal for high current and high-frequency signal applications.

The PTHF100R-40SM also features an improved dynamic temperature coefficient, meaning that it will not be affected by temperature fluctuations and can provide highly accurate and consistent performance over a wide range of temperatures. It is an extremely reliable inductor with a maximum working temperature of +125°C. The device also has an improved radiation resistance, making it ideal for use in environments with high levels of electromagnetic radiation.

In summary, the PTHF100R-40SM is a type of fixed inductor that provides high efficiency and performance in a compact package. It is widely used in RF power amplifiers and various communication products, due to its high inductance rating and precise frequency accuracy. The PTHF100R-40SM also has an improved dynamic temperature coefficient and radiation resistance, allowing for reliable performance in applications with extreme temperatures and high levels of electromagnetic radiation.
