    It is imperative to protect the electronics in a consumer-removable battery pack from ESD damage. Even an upset without permanent damage may be unacceptable to the end-user. Handheld equipment that contains a transmitter also may require protection to guard against improper measurement and/or upset due to the affect of the radio frequency (RF) on the circuitry. Because the RF field strength varies
