RCD’s TF Series construction consists of a thermal fuse welded in
series with a resistor element. The assembly is potted inside a
ceramic case (model TFR fuse is mounted externally in order to
provide field-replaceability of the fuse). Under overload conditions, the
thermal fuse “senses” the temperature rise of the resistor element
and opens upon reaching a predetermined temperature. Devices can
be custom tailored to specific fault conditions and do not require the
large power overloads necessary with other fuse resistors to achieve
proper fusing. Thus, the TF Series offers great safety, since high
temperatures are not involved to achieve fusing. Typical applications
include telecom line cards, repeaters, trunk carrier systems, RFI
suppression, power supply, medical, and automotive circuits.
