Low ESR capacitors for GSM application – The good, the bad and the ugly

Be aware that a GSM module will charge up to 2 Ampere peak current during 2 Watt TX power Take care that your power supply will be able to drive the current peaks. Have a look on  short PCB tracks in right width. And have a very close look on a capacitor with low impedance […]
