Testing and Function of Pattern Braided Sleeve

Pattern Braided Sleeve are one of the basic components of semiconductors. They have the function of current amplification and are the core components of electronic circuits. There are many types of crystal Pattern Braided Sleeve in China, and the arrangement of the pins is different. If you are not sure about the pin arrangement of the Pattern Braided Sleeve during use, you must measure to determine the correct position of each pin, or look up the transistor user manual. Clarify the characteristics of Pattern Braided Sleeve and the corresponding technical parameters and information. Pattern Braided Sleeve are woven from tough environmentally friendly PET monofilaments, which have strong stretchability, wear resistance, flame retardancy and elastic properties.

For the reverse characteristic test, touch the red test lead of the multimeter to the positive electrode of the Pattern Braided Sleeve and the black test lead to the negative electrode of the Pattern Braided Sleeve. If the needle points at infinity or close to infinity, the tube is qualified. To test the positive characteristics, touch the black test lead of the multimeter to the positive electrode of the Pattern Braided Sleeve, and touch the red test lead to the negative electrode of the Pattern Braided Sleeve. If the needle does not swing to 0 but stops in the middle of the dial, the resistance at this time is the forward resistance of the Pattern Braided Sleeve. Generally, the smaller the forward resistance, the better. If the forward resistance is 0, it means the die is damaged by short circuit. If the forward resistance is close to infinity, it means the die is open circuit. Short-circuited and broken pipes cannot be used.
The switching element, the Pattern Braided Sleeve has a very small resistance under the action of the forward voltage and is in the on state, equivalent to an on switch; under the action of the reverse voltage, the resistance is very large and is in the off state, like a disconnected switch. switch. Utilizing the switching characteristics of Pattern Braided Sleeve, various logic circuits can be formed. Knitted sleeves with detection patterns, which play the role of detection in radios. Knitted sleeves with variable volume patterns, used in tuners of television sets. Limiting element, after the Pattern Braided Sleeve is forward-conducted, the forward voltage drop remains basically unchanged (0.7V for the silicon tube and 0.3V for the germanium tube. Using this characteristic, as a limiting element in the circuit, the signal amplitude can be limited to a certain level. Within the range. The relay pattern woven sleeve plays a relay role in the inductance of the switching power supply and in inductive loads such as relays.
