Fixed Inductors

Inductors or chokes are passive components. They oppose the flow of electrical current in circuits. They have multiple applications with various configurations. Fixed inductors are those types of inductors that have a fixed inductance value which is determined by their component design, construction materials, and physical parameters.The HKQ0603S4N3C-T is one such type of fixed inductor which is suitable for high current application. The inductance value of this particular type is 4.3nH. These inductors are surface mountable with 6×3 mm package size. Their inductance tolerance is extremely accurate at ±10%.

Application Field of HKQ0603S4N3C-T

The HKQ0603S4N3C-T fixed inductor finds application in a broad range of electronics and communication as voltage regulators, energy storage and switching regulators, in addition to the RF tuners, cellular phones, Bluetooth, WLAN, GPS, WCDMA, power adapters, and other electronic systems. The high peak pulsecurrent rating, reliable range of inductance, and good stability makes this inductor a versatile choice for high current applications.

Working Principle

A fixed inductor is designed to oppose the flow of electrical current in a circuit, while storing energy. When an AC current is applied to the inductor it stores the energy in the form of a magnetic field, which is created around a conductor, and releases it during the negative cycle of the signal waveform. This process is known as inductive reactance, and it is responsible for a significant part of the impedance experienced by the circuit.The inductor blocks any rapid pulses of current from flowing through the circuit while allowing the correct frequency current to be passed. This helps to maintain the circuit stability and durability during extreme-duty applications like those mentioned above.

Safety

When installing or using the HKQ0603S4N3C-T inductor, it is important to keep it away from any heat sources that can cause overheating and damage the unit. Make sure to read and abide by the recommended safety instructions supplied by the manufacturer.

Conclusion

The HKQ0603S4N3C-T fixed inductor is an excellent choice for high current application. Its high peak pulse current rating, reliable range of inductance, and good stability makes it ideal for use in a range of electronics and communication related fields. But it is important to follow the safety instructions provided by the manufacturer to ensure safe and proper use.
