Magnetic resistance speed sensor of laboratory circuit

The medium and short-range high-frequency wireless communication technology allows non-contact point-to-point data transmission between electronic devices (within ten centimeters); it is used in the fields of access control, public transportation, mobile payment, etc.

At present, the static electricity in the natural environment is everywhere. The electrostatic contact discharge of the human body mode is 8KV, and the air discharge mode is 15KV. In the application of the product, the central office equipment is easily disturbed by the static electricity released by the human body, although it is not noticed by itself, but the bureau The end device chip has to withstand hundreds of electrostatic stresses per day.

For the interface protocol and specification of high-frequency wireless communication, Shanghai Leiqi Electronic Technology successfully developed the electrostatic protection module LC**CI, which is specially applied to high-frequency wireless, which can effectively suppress the static troubles from nature, especially for the bureau of industrial environment. End device.

Product structure diagram is as follows

The product is packaged in SOD323, standard 0805 small package, bidirectional protection, LC**CI's ultra-low capacitance, junction capacitance is only 0.4pF, about 60% of the peer products, can effectively smooth the instantaneous data of high-frequency wireless chip transmission.

LC**CI products are available in a variety of main chip signal voltages, 3V 5V 8V 12V 15V 18V 24V 36V.
