KOA has recently optimised the resistive material and the production process, and is now able to offer the SG73S, SG73P and SG73Gseries also with tighter tolerances of ±1%, ±0.5% and ±0.25%.
The KOA SG73S series is a special anti-surge resistor which is suitable for high peak voltages with short duration (e.g. ESD/CR discharge/rush current).
The SG73P series is a pulse-proof resistor which is suitable in case of higher power than rated power and pulse voltage is applied comparatively long (e.g. gate resistor of FET).
The SG73G series is a high precision pulse-proof resistor with T.C.R. ±50 ppm/K and the same one-pulse characteristics than the SG73P series.
Key features:
- Pulse proof property
- Higher power ratings than std. FC’s
- Supposedly excellent in ESD characteristic (SG73, SG73S)
- High component and equipment reliability
- Resistance range 1Ω to 10MΩ
- Resistance tolerances down to ±0.25%
- Operating temperatures up to 155°C
- Tested acc. to AEC-Q200 requirements
- Anti-sulfuration type also available (SG73S/P_RT).
