RLB0812-391KL

Fixed inductors are passive components used in a variety of electrical circuits, such as radio receivers, computers, digital systems, and motor drivers. As the name implies, these devices remain in a fixed mode for an extended period of time. They, in turn, are responsible for providing inductance into the circuit and dissipating energy. The RLB0812-391KL is an example of a fixed inductor.

It is a low-profile, surface-mount device, with a size of 0.35mm x 0.30mm x 0.30mm, making it convenient for usage in compact electronic components. Additionally, this unit operates in a temperature range of -25° Celsius to 85° Celsius.

Application field and working principle

The key advantage of RLB0812-391KL is its broad application field, which includes computers, automotive electronics, measuring devices, LCD monitors, and more. It use magnetic pulses to build up and maintain a stable magnetic flux in the surrounding circuit, thus creating an inductance at the desired frequency. It is also important to note that a wide range of output current is reliably supported.

This fixed inductor is used in applications that require an increased voltage or frequency. For instance, an oscillator, which is part of the PLL (Phase-Locked Loop), can potentially reduce the noise and ripple generated by the power supplies. This improves the signal-to-noise ratio in the circuit and enhances the overall performance.

The RLB0812-391KL fixed inductor works in a manner similar to how a transformer works. Whereas a transformer uses AC power input to deliver a higher voltage output, the inductor uses a smaller AC input and delivers back a much higher voltage. It is important to note that both the input and output current of this device remain in phase.

Another advantage of this fixed inductor is its EMI (Electro-Magnetic Interference) shielding, which eliminates any electromagnetic noise generated by other components in the circuit and therefore improves the circuit performance. Furthermore, the RLB0812-391KL also boasts a low profile, low profile Q factoron, and low distributed capacitance, all of which enable increased power density and decreased losses.

In addition, this device also has excellent heat dissipation due to its alumina substrate construction. The substrate dissipates heat away from the inductor and thus prevents any damage to the device.

Overall, the RLB0812-391KL fixed inductor has numerous features that benefit a large variety of applications. Its EMI shielding, low profile, low distributed capacitance, and high power density make it an ideal choice for use in a wide range of circuit designs.
