Fixed Inductors: PM1008-1R0K application field and working principleInductors, which are also known as coils or chokes, play an essential role in electrical circuits. They are a type of passive two-terminal electrical component that stores energy in a magnetic field when electric current is running through it. The PM1008-1R0K is a fixed inductor from the PM1008 product series specifically designed for applications in the consumer, automotive, medicine, industrial and aerospace industries. It is an ideal choice for high-current applications due to its robust construction and high-efficiency core material.The PM1008-1R0K inductor is a Type E, surface-mounted component measuring in at only 8.0mm x 8.0mm x 5.8mm. It utilizes a high-temperature bonded ferrite core (BeO or tantalum-nitride), along with copper wire and tin-silver plating. The construction of the PM1008-1R0K is such that it is able to withstand temperatures of up to +105°C without compromising its performance. It operates at a voltage rating of 350VAC and is able to handle up to 650uA of current. This makes it suitable for a wide range of applications, including: mobile phones, DVD players, notebooks, amplifiers and power supplies.The PM1008-1R0K features an inductance rating of 1r0kΩ ±20%, with a maximum DC resistance of 0.05Ω and a low-current DC resistance of 0.028Ω. It also features a high maximum dissipation factor of 1.85 (at 100kHz) and a low maximum temperature rise of +30°C. The PM1008-1R0K is ideal for applications that require high load-drive capacity, such as the switching of large motors.The PM1008-1R0K inductor works based on Faraday\'s Law of electromagnetic induction, which states that the voltage induced in a closed circuit is proportional to the rate of change of the magnetic flux passing through the circuit. The magnetic flux in turn is proportional to the current flowing through the inductor. Thus, when an alternating current (AC) passes through the PM1008-1R0K inductor, the changing flux in the core generates a voltage across its windings which, when integrated, is equal to the current multiplied by the inductance. This voltage opposes the current, thus making the PM1008-1R0K a useful component for controlling AC power. The PM1008-1R0K also has some unique characteristics making it particularly useful in some applications. For example, when connected in parallel with a fixed capacitor, an LC circuit (inductor-capacitor circuit) is formed which can generate a specific frequency. This makes the PM1008-1R0K ideal for use in frequency tuning circuits, which are used in a variety of applications including radio and television tuning.In addition, the PM1008-1R0K can also be used as an adjustable inductor, as its inductance can be easily adjusted by means of a screwdriver. This makes it especially useful for applications that require precise inductance control, such as power filtering or signal processing.Overall, the PM1008-1R0K is an extremely versatile and reliable fixed inductor, and is ideal for a wide range of applications, including consumer, automotive, medicine, industrial and aerospace. It is capable of operating at high temperatures and handling high currents, and is also capable of being used as an adjustable inductor for applications that require precise inductance control.
