Fixed Inductors

The SCMD4D08-270 Fixed Inductor is used mainly for instrumentation, signal processing, low-frequency audio amplifier, radio frequency circuitry, power transmission and various other electronics with these requirements. This type of inductor provides a wide range of inductance values with tight tolerance control.

The SCMD4D08-270 is built with a single, high-quality ferrite core. The standard inductance ranges are 7 mH, 8 mH, 10 mH, 11 mH, 15 mH, 17 mH, 19 mH, 21 mH, and 24 mH. The inductance can be adjusted to 6 decimal places (in mH) for accurate tuning.

The SCMD4D08-270 has a very low DC resistance of 30 ohms and no drastic change in inductance due to temperature variations. The inductor features low loss to minimize heat generation and bridge power dissipation. The operating temperature range is-40 to +85, and the Q factor is typically greater than 300 at frequency of 1KHz. The maximum peak current is 13.2A.

The SCMD4D08-270 inductor uses an internal magnetic shield. The enclosure is an epoxy resin and the inductor is sealed with an inner layer of epoxy resin to provide excellent environmental protection. The shielded core results in small variation of inductance tolerances and a very low noisemaking level.

The working principle of the SCMD4D08-270 inductor is based on Faraday’s Law, which states that when a changing magnetic field or electric field is applied to an inductor, an emf is induced in it. In the case of an inductor, the producing of an emf is accomplished by changing the magnetic field in the inductor. This is done by changing the current which passes through the inductor. As the current passes through the inductor, the field lines create a circle of flux around the inductor. The intensity of the flux depends on the amount of current. As the current increases, the flux increases, and vice versa. As the current passes through the coil, the flux is cut by the coil windings, and an emf is induced in the coil.

The SCMD4D08-270 fixed inductor is used in many different types of circuits and devices, including: voltage regulators, power supplies, radio frequency (RF) circuits, instrumentation, communications, and audio amplifiers. It is also used as a bypass capacitor in power supplies to filter out unwanted noise and ripple.

In conclusion, the SCMD4D08-270 fixed inductor is a component which has a wide range of uses in electronics and can be tuned precisely with a high degree of accuracy. Its small size, low DC resistance, and high Q factor make it ideal for many devices.
