Fixed Inductors

Inductors are essential components of various types of electronic circuits, including filters, tuners, and oscillators. Fixed inductors are devices that provide magnetic flux and act as electric current generators. One type of fixed inductor is the P160-472HS, a litz wire wrapped device that exhibits high inductance and high current operation resulting in a wide range of applications.

P160-472HS Application Field

The P160-472HS can be used in various applications, including regulated power supplies, DC motors, switching converters, and signal generators. The device has a wide operating temperature range of -55°C to +125°C and a high self-resonant frequency of 10MHz, making it suitable for high frequency applications. Additionally, it has a high saturation current, low DC resistance, and tight tolerance down to 10%.

As an example of the P160-472HS being used in power supplies, it can be configured as a power factor corrector (PFC). The PFC converts AC power flow into DC and provides an efficient way to transfer energy without dissipating power. By increasing the power factor, the total harmonic distortion of the power waves is minimized while the current system losses are reduced. It can also be used to stabilize the output voltage and reduce the chances of damage from overvoltage.

P160-472HS Working Principle

The P160-472HS uses a litz-wire wrapping technique. This wrapping technique consists of several insulated conductors bundled together that are wound generally around a central core, providing inductance and bypassing high frequency eddy currents that may otherwise increase power losses. Further, it enables maintaining a low temperature rise even at higher power concentrations, enabling high current operation.

The winding of the litz wire around the core also generates a magnetic field. This magnetic field provides magnetic flux, which the P160-472HS uses to store, regulate, and transfer electrical energy. Using the Self Induction principle, if the current through an inductor changes, the voltage across the inductor will change in order to maintain a constant current. This can be used to reducevoltage spikes and to stabilize the output of power supplies.

The P160-472HS also offers outstanding thermal stability which helps the device handle extreme voltage conditions up to 125°C. The device also has an impedance with relatively low DC resistance so that reactive power is minimized. All these properties make it ideal for multiple application fields, including regulating power supplies and DC motors.

Conclusion

The P160-472HS is a type of fixed inductor, a device with multiple applications in regulated power supplies, DC motors, and signal generators. The litz-wire winding technique of the P160-472HS provides high inductance and high current operation, with a wide operating temperature range, high self-resonant frequencies, and high saturation current. With the Self Induction principle, the current through an inductor changes, but the voltage across the inductor stays constant allowing for stabilization in the output of power supplies. This makes the P160-472HS an excellent choice for its application fields.
