IPP IPK For circuits that utilize additional series resistance, the surge current rating (IPP) of the TeleLink SM Fuse should be greater than or equal to the available surge currents associated with the lightning immunity tests of the applicable regulatory requirement (IPK (available)). IPP IPK (available) The maximum available surge current is calculated by dividing the peak surge voltage (VPK) by the total circuit resistance (RTOTAL). IPP IPK (available) = VPK/RTOTAL For longitudinal surges (TIP-GND, RING-GND), RTOTAL is calculated for both TIP and RING. RTOTAL = RTIP + RSOURCE RTOTAL = RRING + RSOURCE For metallic surges (TIP-RING): RTOTAL = RTIP + RRING + RSOURCE To select the most appropriate TeleLink SM Fuse / SIDACtor TVS combination, simply decide what regulatory requirement your equipment will need to meet and refer to the following table.

A 1oz. .025" width is recommended, but reference to the IPC D 275 standard may provide more precise details. For UL1950 compliance, design considerations must be given to the test conditions of Annex NAC. In particular, test 3 and 3A are intended to produce the maximum heating effects. Therefore, PCB layout design should compensate appropriately.
