Edited by the Electronicstalk editorial team Nov 5, 2003
In response to pending European regulations on hazardous substances, Microtherm now offers an eco-friendly thermal fuse with more temperature ranges and more rated currents.
In response to pending European regulations on hazardous substances, Microtherm now offers an eco-friendly thermal fuse with more temperature ranges and more rated currents.
Two Sefuse types are available.
The current SF type does not contain lead (Pb) but uses cadmium (Cd) in the sliding contact.
The material of the sliding contact for the new SF type does not contain cadmium and uses an organic thermosensitive material as the thermal element.
The current SM type contains lead and some contain cadmium.
For the new SM type a new fusible alloy material has been developed and does not contain lead and cadmium.
There are three new temperature ranges available - 87, 142 and 151C - for the SM/G, SM/B and SM/A Series.
Extended current ranges include: the new SF/K 6A version; the SF/E 10A version; and the SF/Y 15A version.
All are rated at 250V AC and, most importantly, cadmium free.
