Surface-Mount ESD protection component by Firstohm: ESD Surge Absorber MELF (ESM)

2019-11-30
Introduced in 2010, Firstohm Spark Gap Surge Absorber SGS series as most of you may already know, is the first non-resistor product by Firstohm. SGS protects the circuits (and other components) by acting as a switch and
short-circuiting unwanted electrostatic
discharge (ESD) through the porous layer
when the spark-over voltage is exceeded.
Eliminating gas tubes (or ceramic tubes) and
special gas that are essential for the conventional gas discharge tubes, SGS series would help
reduce surge protection related costs in a network setup. Furthermore, Firstohm SGS has the
advantages of high insulation resistance, low capacitance, and fast response time.
This year, in response to increasing market demand for smaller circuit designs with unaffected,
or sometimes even more powerful, performance, Firstohm further introduced ESD absorber in
surface-mount cylindrical packaging - ESD Surge Absorber MELF (ESM series).
