Fixed Inductors are an essential and key component in circuits ranging from low power analog to high power RF applications. Their use includes high frequency magnetic coupling and energy storage. Among the many types of fixed inductors available, PE-0402CC3N9STT is a type of high performance, miniature, high frequency, surface mount inductor designed by Pulse Electronics Corporation.

The PE-0402CC3N9STT is mainly used in circuit applications such as voltage regulator, low-noise active circuits, and energized audio applications which require intensive energy storage and strong EMI/RFI suppression. The device offers inductance values of 0.1µH, 0.33µH, and 0.47µH and has a maximum DC resistance of 0.2Ω. The device is made of high temperature ferrite core material with a class of "H" in 3-terminal design. It can be used for a wide range of current production such as 3.0A. Additionally, it has excellent solderability along with high thermal shock resistance.

The PE-0402CC3N9STT is designed using a carefully developed and optimized magnetic core that enables it to work within the frequency range up to 6GHz and to provide symmetrical magnetic field which helps minimize signal distortion and noise emission.

The PE-0402CC3N9STT is composed of three parts – primary, secondary, and tertiary with symmetrical windings. The windings are wrapped into the ferrite core induction plate. The current running through the primary winding creates a magnetic field in the ferrite core induction plate. This magnetic field then penetrates into the secondary winding to induce a magnetic flux. The amount of energy stored in the secondary winding is proportional to the amount of energy stored in the primary winding. This energy is then transferred back to the tertiary winding after a certain period of time and delivered to the output.

The working principle of the PE-0402CC3N9STT can be simply explained as the self-induction phenomenon. The device works similarly to a transformer but without exchanging energy between two windings. Instead, the energy is generated from the primary winding and transferred to the tertiary winding. The self-induction phenomenon occurs when a change in current occurs in the primary winding. This causes the magnetic field in the ferrite core induction plate to change and thus inducing energy in the secondary winding.

The PE-0402CC3N9STT provides a cost-effective solution to EMI/RFI suppression in applications that require high frequency and high efficiency performance. The device has a high inductance-to-volume ratio and a wide range of current production options. It is an ideal solution for applications such as voltage regulation, low-noise active circuits, battery chargers, and energized audio applications. The device is suitable for automated surface mount assembly and offers excellent solderability and high thermal shock resistance.
