ESD TVS electrostatic protection tube 0201 package 3.3V ultra low capacitance ESD

The ultra-small multimeter is only 40X/80X17MM, which can be easily placed in the pocket of your clothes or hung on your waist.
As shown in the figure, the outline of the ultra-small multimeter is shown as its internal circuit. The head of the circuit adopts the commonly used 91L16 type O~3OOV small voltage meter, and the internal resistance of this small head is 430Ω. The full-scale current is 0.5mA, if the reader's head is not enough for this parameter. Then you need to reset the external component values.
The ultra-small multimeter has six gear positions, namely AC 500V, DC 2.5V, 25V, 250V voltage and RXlkΩ resistance and DC 0.5mA current. The gear position changeover switch K1 is a common two-knife three-position toggle switch. Another knife double position switch K2 is equipped with cooperative function conversion. The battery used for electrical blocking is a VR22 type 12V battery. The pen is made of hard and thick wires, and it can also be welded with a pair of small alligator clips. The electrically blocked zero-potentiometer uses an adjustable resistor with a plastic cap. The resistance of the meter needs to be redrawn.
