Fixed InductorsFixed Inductors are components that are designed to maintain a steady, unchanging flow of electrical current. They are commonly used in applications where either an electrical signal needs to be sent directly to a power source or an electrical signal needs to be kept from changing too quickly for long-term stability and accuracy. Inductors are used in numerous electronic applications including power control, filtering, and motor driving, and are frequently found in power supplies, filters, antennae, control systems, and audio devices. One of the most commonly used inductor designs is the CDR7D28MNNP-331NC type. This fixed inductor does not require any external components such as capacitors and it is rated to operate at temperatures between -40°C and +125°C. It has a rated inductance of 0.33µH and a temperature stability of up to ±30% over the specified operating temperature range. The maximum working voltage of the CDR7D28MNNP-331NC is rated at 50V and its resistance is rated at 6.9mΩ.The working principle for a fixed inductor is based upon the idea of inductance, which is the resistance of a conductor to AC signals. When an electrical signal is introduced into a winding, a coil of wire is formed within the inductor. This coil will then generate a magnetic field in the vicinity of the conductor. As the voltage is increased, the current that is induced by the magnetic field begins to increase as well, which causes a drop in voltage across the inductor and the current flow within it is restricted.This type of inductance is particularly useful whenever a circuit is designed to operate within a limited frequency range. In these applications, the current flow can be restricted within a certain frequency range, thus maintaining reliable and accurate current values over an extended period of time. The resistance of the coil also helps to impede unwanted electronic components from entering into the circuit and interfering with the desired functionality. Furthermore, any sudden or rapid changes in the voltage and current levels are resisted by the inductor, thus providing a higher degree of stability and accuracy within the circuit.The CDR7D28MNNP-331NC is a very reliable and accurate fixed inductor, making it ideal for applications that require high voltage and current levels. Its high temperature stability rating makes it suitable for applications that require a constant, stable performance over extended periods of time. Its maximum working voltage of 50V makes it well-suited for applications in which higher voltage levels are required. In addition, the resistance of the coil helps to protect the circuit from unwanted interference, offering an increased degree of accuracy over extended periods of time. Finally, its wide operating temperature range of -40°C to +125°C ensures that it can be used in a variety of engineering and scientific applications.
