Fixed inductors are electric components used in applications such as power supplies, oscillators, and radio-frequency circuits. There are two main types of inductors - those wound from a single continuous wire and those of a laminated construction. The P3519-125K is an example of the latter category. It is an encapsulated fixed inductor with a rated inductance of 125mH and a rated current of 1.2A.The P3519-125K has an operating temperature range of -40°C to +125°C. The component is equipped with two leadframes that are formed of tinned copper and soldered to the substrate. Two insulated coils made of enameled copper wire are wound in the space between the two leadframes. These coils are connected in series to form the inductive element.The primary application of the P3519-125K is in DC-DC converters. It is ideal for this purpose due to its low resistance and high power rating. The 125mH inductance of the component ensures an increased output voltage ripple rejection, making it an excellent choice for DC-DC converters. Additionally, the high operating temperature range allows for increased power dissipation and thus higher efficiency in the device.The working principle of the P3519-125K is based on the magnetic field generated by the two coils. When a current flows through the inductor, it creates a magnetic field. This magnetic field induces an opposing voltage, which is proportional to the rate of change of the current through the inductor. This voltage is added to the source voltage and is known as the self-induced voltage. This self-induced voltage reduces the total voltage seen by the load.The P3519-125K has a wide range of application areas, such as switching regulated power supplies, resonant converters, switching DC-DC converters, broadband amplifiers, sinusoidal oscillators, and TV signal modulators. It is also suitable for use in projects where size and cost are important factors, such as in portable appliances or medical devices.In summary, the P3519-125K is a fixed inductor with a rated inductance of 125mH and a rated operating temperature range of -40°C to +125°C. It is most commonly used in DC-DC converters and is ideal for applications where size and efficiency are important. The working principle of the component is based on the magnetic field generated by two coils, which induces an opposing voltage. This self-induced voltage reduces the total voltage seen by the load. As such, the P3519-125K is a versatile component that is suitable for a wide range of applications.
