Buttons / Keyboard Protection

Problem: Electrostatic Discharge (ESD)

An electrostatic discharge (ESD) event caused when the user presses the equipment buttons can cause damage to the internal circuitry of the device.

 

Solution: PESD devices

Extremely low capacitance ESD protection devices, such as Raychem PESD devices, help shunt ESD away from sensitive circuitry in electronic devices without inducing signal distortion.
