Overview of the Fixed Inductors
The fixed inductors form the backbone of any electrical or electronic system. They are the fundamental components in the main electric circuits. They generally consist of two or more conductive coils or windings represented by inductors, and can be found in numerous applications or implementations for a variety of purposes, including:	
	
Signal transmission in the audio, radio, and communication systems
	
Filtering and the separation of frequencies in the control system
	
Power conversion in switched-mode power supplies and DC-DC converters
	
Mixing in the direct current power and winding systems
	
Connection of two-wire networks and the capacitors
	
Stabilization of the oscillation circuits
	
Switching and protective functions in the high-current circuits
	
PL8400T Inductors
The PL8400T series of three-terminal fixed inductors, which is designed and manufactured by Pulse Electronics, is specifically designed for used in switch-mode power supplies (SMPS) and DC-DC converters. It is a comprehensive product line that comprises of small-profile coils, which are capable of dissipating high heat and managing peak power demands well. It has a wide operating temperature range and provides the users with excellent temperature stability. In addition, PL8400T inductors feature a rugged construction with improved mechanical strength and can easily tolerate high shock currents.
Working Principles of PL8400T Inductors
In a three-terminal fixed inductors, the coil is usually made of a single piece of conductive metal (or a conductive material) with the three terminals connected to each end of the coil. The current is then passed through the coil, creating a magnetized magnetic field and creating an alternating current (AC) signal. This is then fed into a transformer which amplifies the inductance.The magnetic field is further enhanced by the application of a magnetic core (made from ferrite, nickel, iron, or another magnetic material) onto the coil. This increased inductance further amplifies the signal and provides higher power efficiency and voltage stability.The core can also be used as a filter to separate different frequencies, as it can be tuned to a certain frequency. This can help to reduce noise and interference in the signal.
Applications of PL8400T Inductors
The high-performance and power efficiency of PL8400T inductors make them suitable for a wide range of applications.They are often used in electronic control systems for interfacing and connection to various electrical and electronic components, such as switching power supplies, DC-DC converters, actuators, sensors, and signal processing circuitry.They can also be used for signal transmission in the audio, radio, and communication systems as well as in the power converters, motor controllers, and tuning circuits.The PL8400T inductors also prove useful for protecting electrical circuits against overcurrent and short circuiting. Using the appropriate inductors, the power module can be protected against power surges and spikes even in the absence of a fuse.
Conclusion
The PL8400T series of three-terminal fixed inductors offers excellent performance and reliability, making them ideal for a wide range of applications. From power conversion in switched mode power supplies to signal transmission in audio, radio, and communication systems, these inductors are capable of delivering high-power efficiency and increased temperature stability.
