Fixed Inductors: B78148T1122K9

Fixed Inductors are electrical components that create a magnetic field when current passes through them. In electronic circuits, inductors are used to store and release electrical energy, and to filter out unwanted disruptions or noise. The B78148T1122K9 is a type of fixed inductor, specifically designed for use in noise and interference attenuation circuits.

Application Fields of the B78148T1122K9

The B78148T1122K9 is typically used in mobile phones and other handheld devices, where its wide range of inductance values makes it suitable for use in a variety of applications. It is often used in noise suppression and electromagnetic interference (EMI) attenuation circuits, where it performs an important role in controlling circuit noise both within the device and outside it. As such, the B78148T1122K9 is a critical component in the performance of mobile devices.

Benefits of the B78148T1122K9

The B78148T1122K9 is one of the smallest inductors on the market, with a size of only 0.5 mm³. This tiny yet robust component is highly resistant to shock and vibration, making it an ideal choice for applications in rugged environments. It features an excellent Q factor of up to 100, meaning it can effectively reduce circuit noise, and its low profile makes it suitable for use in areas where space is at a premium. The B78148T1122K9 also benefits from a low DC resistance, low loss, and high thermal stability.

Working Principle of the B78148T1122K9

The B78148T1122K9 is a fixed inductor, meaning it is designed to generate a magnetic field of constant strength in the presence of an electric current. This is achieved by wrapping the component’s copper wire around a cylindrical core made of ferrite. As current passes through the wire, it generates a magnetic field, which is then stored in the core and released in the form of an inductance. It is this inductance that is used in noise and interference suppression circuits.

Conclusion

The B78148T1122K9 is a type of fixed inductor, specifically designed for use in noise and interference attenuation circuits in mobile phones and other handheld devices. Its miniature size, low profile, and excellent performance make it an ideal choice for such applications, as it can effectively reduce circuit noise while taking up minimal space. The component also benefits from a wide range of inductance values and high durability, making it suitable for use in rugged environments.
