Electrostatic discharge on the 3.5 headphone jack What effect
Electrostatic discharge on the 3.5 headphone jack What effect3.5 Headphone Jack Electrostatic Discharge (ESD) is a charge transfer that occurs when objects with different electrostatic potentials are close to each other or are in direct contact with each other.
When the friction between objects, collision or the occurrence of electric field induction, will cause the surface of the charge accumulation of static electricity.
When the external conditions are appropriate, the accumulation of electric charge will also produce electrostatic discharge, the serious situation can make the socket components of local damage or breakdown, or even cause fire, explosion and other serious consequences.
Especially with the widespread use of polymer materials, more prone to electrostatic phenomena, and 3.5 headphone jack and other components of the trend of miniaturization, making the increasingly serious harm to static electricity.
Sockets and other electronic components in the transport and assembly process may be damaged due to electrostatic discharge, and it is difficult to identify with the eyes out.
So must take electrostatic discharge protection measures.
For example, ESD protection diodes can be used, it is a new rejection of integrated electrostatic discharge protection devices, typical products are DS9502, DS9503. ESD protection diodes should be connected in parallel between the incoming (or outgoing) end of the protected circuit and ground.
