Fixed Inductors

Fixed inductors feature winding coils of electrically conductive material which will store energy in the form of a magnetic field when energized. Inductors, also known as choke or coil depending on their application, are components of electrical circuits designed with both inductance and resistance. This enables them to act as a current limiter, filters, reactors and as tuned circuits. The CTX01-19081-R inductor is a part of the CTX01 series from Aligent Technologies designed for high-frequency switch mode power supply (SMPS) applications. The device is constructed on a SLB09467T-182-68P planar core and features enameled copper wire wound on the core, designed to help control or limit the effects of electrical noise caused by rapid changes in current. The device also features a protective coating, self-bonding copper tape on the terminals and a degreased high temperature rating.

Application Fields:

The CTX01-19081-R inductor is designed to be useful for a wide range of SMPS applications, including 50/60Hz switching power supplies, voltage converter regulators, switched capacitor voltage regulators, and power factor controllers. It has a maximum RoHS operating temperature of 125°C and is designed to operate at up to 500 Volts with an inductance value of 68µH.

Working Principle

The device is based upon the principle of inductance, which states that an electrical current generates a magnetic field. The magnitude of the field is then determined by the amount of current passing through it and its geometric size. The copper windings on the CTX01-19081-R are wound in such a way that they produce a very narrow magnetic field, which is known as a high-frequency inductor.

The CTX01-19081-R inductor works by limiting or controlling the current flowing through it. This is done by creating a dissipative power loss in the winding, which experiences a decrease in its electrical charge when the current flow rate increases. This dissipative power loss creates resistance, which effectively limits the amount of current travelling through the inductor. This serves to protect other components in the SMPS circuit, as too much current can damage the components, and reduce the reliability of the system as a whole.

The CTX01-19081-R inductor is designed with a wide operating temperature range, enabling it to perform reliably on a wide range of SMPS designs. This enables it to be used in a multitude of applications, such as low/high-power applications, low/high-voltage applications, automotive applications, and consumer systems.
