Fixed inductors are a type of electrical component whose inductance is constant with the passage of time and frequency. They are relatively simple components used in numerous applications, including power supplies, amplifiers, radio receivers, and navigation systems. The term ‘fixed’ is used to indicate that the inductance value remains constant regardless of other variables, such as temperature changes. The RCP1317NP-121L is a fixed inductor designed to facilitate signal processing and EMI/RFI filtering applications.

Application Field

The RCP1317NP-121L fixed inductor is primarily used in signal filtering applications. It can also be used for signal coupling and decoupling, and noise suppression applications. Its small footprint allows it to be incorporated into high-density PCBs and used in compact electronic systems. It features a rated current of 1.4A, an inductance of 0.12μH, and an SRF of 17.0MHz. Its low dissipation factor (< 0.002 at 100 kHz), low profile dimensions (2.5 x 5.5mm) and high Q factor (21.3  @100kHz) make it an ideal choice for high frequency circuits, where its high current capacity and low DCR provide significant performance advantages.

Working Principle

The RCP1317NP-121L fixed inductor operates on the principle of electromagnetism. According to this principle, a current flowing through an inductor produces a magnetic field that induces an electromotive force in its core. This electromagnetic force produces a counter-flow current that lags behind the original current, thus producing a reduction in the flow of electric current. In the RCP1317NP-121L, the primary current flowing through the copper coil creates a series of magnetic fluxes of alternating polarity. These flux fields induce a voltage in the secondary coil, producing the desired effect.

The RCP1317NP-121L also features a shielding can, which helps to reduce the amount of EMI/RFI radiation generated by the inductor. The can also serves to reduce the amount of external noise and interference from other components within the system. The combination of the inductor\'s high current capacity and electromagnetic shielding provides a reliable solution for a variety of applications requiring protection from noise and electromagnetic interference.

Conclusion

The RCP1317NP-121L fixed inductor is designed to facilitate signal processing and electromagnetic interference/radio frequency interference (EMI/RFI) filtering applications. Its small footprint allows it to be incorporated in high-density printed circuit boards (PCBs) and used in compact electronic systems, while its high current capacity and low DCR (DC resistance) provide significant performance advantages. Moreover, its shielding can helps reduce EMI/RFI radiation and protect the inductor from external noise and interference. The RCP1317NP-121L can be used for signal filtering, coupling, decoupling, and noise suppression applications in a variety of industries, including telecommunications, automotive, medical, audio applications, and more.
