ADSL Modem-Product application

Item suggestion

CH series

For instead of SIDACtor series and cost down, FOR FCC PART 68SURGE and surge could up to 6KV(10/1000 test up to 1500A) the respond time is 0.5ns, good protection.

Telecommunication charger application information

※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.
