2474-38K

Fixed Inductors are components that store electrical energy in the form of magnetic fields. They are mainly used in power supplies and for EMI/RFI suppression. The most common type of fixed inductor is the 2474-38K, which is used in many applications.

The 2474-38K is designed to be used in high frequency, low voltage applications and is most appropriate for moderate to low current circuits. It is a non-polarized, two-pole inductor that is designed to have an extremely high Q factor. This type of inductor is ideal for applications such as low-noise audio circuits, RF circuits, and switching power supplies. The 2474-38K also features a self-shielding structure that helps reduce EMI emission.

The working principle of fixed inductors is based on Faraday\'s law of electromagnetic induction. This law states that the voltage induced in an inductor changes with the rate of change of the current passing through it. When current passes through an inductor, it sets up a magnetic field around the inductor\'s core. This magnetic field, in turn, induces a voltage in the inductor, which is referred to as counter emf. Since the counter emf opposes the applied voltage, this results in the inductor\'s resistance increasing with increasing frequency.

The 2474-38K specifically is designed to have a high Q factor which results in higher inductance for a given amount of current. The 2474-38K is also engineered with a shielded core that helps reduce the RF emissions and also acts to reduce the inductor\'s self-resonance frequency. This helps ensure that the inductor will operate at the desired frequency.

The 2474-38K fixed inductor is an ideal device for a variety of applications. It is well suited for use in RF and audio circuits due to its high Q factor and self-shielding feature. The 2474-38K is also well suited for use in switching power supplies and emi/rfi suppression due to its ability to reduce EMI emissions.

In summary, the 2474-38K fixed inductor is an ideal device for a variety of applications. It is designed to have a high Q factor, self-shielding feature and an ability to reduce EMI emissions. As such, it is ideal for use in low-noise audio circuits, RF circuits, and switching power supplies.
