Fixed inductors are designed for applications that require fixed inductance at a given frequency. An example of this is the B82412A1102K8, which is a high-grade, open-style, shield-type, low-profile surface-mount inductor. The device is built with a core that is made from ferrite and wrapped with a copper or aluminium winding. The result is an inductor that has a high inductance value and excellent power handling capabilities. This makes it an ideal choice for use in power rectification circuits, dc-dc converters, and high-voltage power supplies.The B82412A1102K8 consists of two coils in a double-coil, single-layer configuration. Each coil has a separate, grounded copper conductor attached to its center, which serves as a shield. The coils are insulated with a wax or oil-based insulation material and epoxy-coated for moisture and corrosion protection. The device has a maximum inductance of 121 nH and a maximum rated current of 1.2 A.In terms of dimension, the B82412A1102K8 is 8.15 mm in diameter and 2.3 mm in height with a weight of only 2.6 g. The device boasts a high thermal resistance of 150 °C/W, which makes it suitable for use in high-temperature environments. The device also has a wide operating temperature range of -40 to +125 °C.The device\'s working principle is relatively simple. When an alternating current (AC) flows through the inductor, it creates a magnetic field which in turn induces a voltage in the inductor and generates a back-EMF. This back-EMF opposes the current, resulting in a voltage drop. This voltage drop is proportional to the current flowing, so that the voltage drop decreases when the current decreases. So the key function of the inductor is to produce a voltage drop, which in turn controls the current flowing in the circuit.In summary, the B82412A1102K8 is a high-grade open-style, shield-type low-profile surface-mount inductor. It has a high inductance value and excellent power handling capabilities, making it suitable for applications such as power rectification circuits, dc-dc converters, and high-voltage power supplies. It is capable of withstanding high temperatures and has a wide operating temperature range. Its working principle is based on the fact that an alternating current creates a magnetic field which induces a back-EMF that opposes the current, resulting in a voltage drop. This makes the B82412A1102K8 a useful inductor for a range of power electronics applications.
