SMD power inductors are one of the metallic glass uranium resistors. Common mode inductance, also known as common mode choke, is often used to filter out common mode electromagnetic interference signals in computer switching power supplies. In the design of the circuit board, the common mode inductor also functions as an EMI filter to suppress the electromagnetic wave generated by the high-speed signal line from radiating to the outside. It is a resistor made of a mixture of metal powder and uranium glass powder, which is screen-printed on a high-power SMD power inductor on a substrate. Good wettability, high temperature resistance, low temperature coefficient. The use of nominal assembly technology has been very common, and the proportion of electronic products assembled by SMT has exceeded 90%. my country should have entered SMT skills since the 1980s. With the development of small SMT production equipment, the scope of use of SMT categories has been further expanded. Aviation, aerospace, instrumentation, machine tools and other categories also use SMT to produce various small batches of electronic products or parts.

Resistors are individually called resistors in daily life. A current-limiting element connected to a resistor in a circuit. The resistor has a fixed value of two pins and is used to limit the current flowing through the branch to which it is connected. The resistance whose resistance value cannot be changed is called a fixed resistance. Those with variable resistance are called potentiometers or variable resistors. The virtual resistance is linear, that is, the transient current through the resistance is proportional to the applied transient voltage. Variable resistor for voltage divider. One or two movable metal contacts press tightly on the exposed resistor. The contact position determines the resistance between either end of the resistor and the contact.

Features of SMD power inductor manufacturers’ products
Small size and light weight; · Suitable for reflow soldering and wave soldering; · The motor can be strong and sturdy; · Low assembly cost, matching with active installation equipment; · High mechanical strength and high frequency characteristics. In order to protect the wires, loops and coils from the external magnetic field and reduce the interference effect of the electromagnetic field generated by the circuit on other components, magnetic shielding or electromagnetic shielding methods are usually adopted.
