SDE1006A-680K Inductors, Coils, Chokes

Fixed inductors are passive electrical components that often appear in radio frequency circuits. The SDE1006A-680K is one such type of fixed inductor. It has a variety of applications and a relatively simple operating principle. This article will discuss the application field and working principle of the SDE1006A-680K.

Application Field of SDE1006A-680K

The SDE1006A-680K is a miniature inductor with dimensions of 1.03 mm × 0.35 mm × 0.53 mm. According to the manufacturer, it can be used in frequency oscillators, SMPS circuits, RFI energy filtering, mobile phone antennas, and power inverters. As this component is small and lightweight, it is also suitable for compact electronic equipment.

The SDE1006A-680K can handle either DC or AC current. Its inductance value is 0.68μH (min) and its DC resistance is 16mΩ (max). Its impedance characteristic allows the frequency of the signal being transmitted to remain relatively constant. It has a temperature coefficient of 100ppm/°C for DC bias, which ensures its working frequency is not affected by temperature changes in the environment.

Working Principle

The SDE1006A-680K is composed of two parts: a coil and a core. The coil is usually made of a copper or aluminum wire while the core is usually made of a ferromagnetic material. When a current passes through the coil, it creates a magnetic field which in turn produces a voltage on the other side of the coil. This voltage is what allows the SDE1006A-680K to function as a fixed inductor.

The value of the inductance is determined primarily by the number of turns of the coil and the core material. The core material determines the size and strength of the field, while the number of turns of the coil determines the number of cycles the current goes through before completing the circuit. This in turn determines the amount of voltage produced in the circuit.

Conclusion

The SDE1006A-680K is a fixed inductor which is used in a variety of applications such as frequency oscillators, SMPS circuits, RFI energy filtering, mobile phone antennas, and power inverters. It is composed of two parts: a coil and a core, and its inductance value is determined by the number of turns of the coil and the core material. The SDE1006A-680K can handle either DC or AC current and its impedance characteristic allows the frequency of the signal being transmitted to remain relatively constant.
