※MLE ESD series the capacitance could according to customer request!
Capacitance 5PF~3000PF)
size(0402~1210)
General, people will use diode in USB 1.0, therefore in USB 2.0 the speed increase, the capacitance is the major key. Our products meet IEC61000-4-2 LEVEL 4 specification and very good protection in ESD problem.
