ABSTRACT:
A surge protector, particularly for protecting components in a telecommunication system, has a thin ceramic substrate on a surface of which is formed a surge protector resistor having a spiral pattern in the form of a double spiral having two parallel resistor paths in series, the width of the paths and the distance between adjacent path lengths being relatively narrow. Resistance trimming links are provided for increasing the length of a resistor path, there being substantially even distribution of surge effects under surge conditions.
