thick film resistor element
■
Anti-leaching nickel barrier terminations
■
Superior to chip resistor of RK73 series in surge
withstanding voltage and pulse withstanding voltage
■
If tight tolerances (down to ±0.5%) are requested, the
SG73S
(for surge)
and the
SG73P (for pulse)
are ideal
■
Ideal for use in E.C.U’s and in circuits to catch
inductive lightning surge
■
Rated ambient temperature: +70° C
■
Operating temperature range: -55° C … +155° C
■
Parts are tested according to AEC-Q200 requirements
■
Meets or exceeds IEC 60 115-8, JIS C 5201-8, EIAJ RC-2134C
■
Suitable for reflow and wave soldering
