FLAT CHIP
SURGE CURRENT
THICK FILM
SG73 • SG73S • SG73P
FEATURES
■ RuO2 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 SP73P (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
■ Meets or exceeds IEC 60 115-8, JIS C 5201-8, EIAJ RC-2134A
■ Suitable for reflow and wave soldering
