Fixed inductors are electrical components that store energy in the form of an electromagnetic field, in other words, they act as tiny coils of wire, conditioning the flow of electricity. One specific type of fixed inductor is the RLF12545T-7R8N5R4-PF. Understanding the application field and working principle of this model can help to incorporate it into a project.

RLF12545T-7R8N5R4-PF Application Field

The RLF12545T-7R8N5R4-PF is a miniature, surface-mount, shielded inductor used primarily in cellular handset applications. It offers a wide operating temperature range between -40C and +85C, low current noise (1.5uV max at 20 - 40MHz), and high efficiency values (68% maximum at 10MHz). Accordingly, this inductor is especially well-suited for power-sensitive, RF circuits that require a small size, low power consumption, and high impedance.

Working Principle

A fixed inductor consists of one or more turns of insulated wire coiled on core material. When a current passes through the wire, it creates a magnetic field in and around the core material which increases in strength as the amount of current passing through it increases. This magnetic field can then be used to induce voltage in other parts of the circuit. This effect is utilized in the RLF12545T-7R8N5R4-PF to act as a buffer in a cellular phone circuit, reducing the power dissipated from the circuit. This helps to extend the battery life of the phone, as power is diverted away from sensitive components.

Conclusion

Understanding the application field and working principle of the RLF12545T-7R8N5R4-PF fixed inductor can help to determine whether or not it is the right choice for a particular project. This model, specifically suited for cellular handset applications, has a wide operating temperature range and offers low noise and high efficiency values for RF circuits that require small size, low power consumption, and high impedance.
