What role does SMD inductor play in LED energy-saving lamps?

Since chip inductors can extend the service life of many consumer electronic products, improve the quality of products, abnormal quality, and performance, they have been put into use by many manufacturers.

Not only applied to power supply devices, but also audio equipment, terminal equipment, household appliances and other electronic and electrical products, so that electromagnetic signals are not interfered, and at the same time, it does not actively interfere with the signals or electromagnetic radiation emitted by other surrounding equipment. .

Energy-saving lamps are widely used in our lives; and LED energy-saving lamps are mainly composed of semiconductor light-emitting diodes; they are a kind of light that consumes less power and has a relatively long service life.

The internal circuit of the LED energy-saving lamp is a power circuit board, mainly including electrolytic capacitors, resistors, power inductors, ceramic capacitors, etc., of which a relatively small number is chip power inductors, and its role is more important.

is mainly to block AC and DC, and block high frequency and low frequency (filtering). Of course, the power circuit mainly blocks AC and DC. It can be seen that the resistance of chip power inductors to DC is almost zero.

Under the current condition that the circuit allows to pass, the chip inductance hinders the passage of the AC point, protects the circuit board from being damaged, and greatly increases the service life of the LED.
