Integrated circuit block
Main characteristic
- The response speed is fast
When the electric current has appeared in a , on the b line, microelectronic switch movements of the integrated circuit, response time is smaller than ten microseconds , than such 1 million times faster the above of the components and parts as PTC,etc., one grade is protected and protected faster than second, realize the protection of the equipment effectively fast;
- Performance consistency is good
FA9-220J type
The products data are dispersed and small, benefit quality control, every performance is safe , steady , reliable ;
- Excessive pressure , pass while shedding outputting the warning signal
In passing it flow> 150mA at can last warning signal,favorable to computer lab management of, prevent the accident from occurring
- Excessive pressure , passing to flow to resume time short
FA9-220J1 type
The electric current passes to assault and resume time <1S; The overvoltage assaults and resumes time ¡Ü 30mS
- Surface temperature is low
 FA9-220J2 type
Overvoltage integrate pieces of low surface temperature at passing electric current, reduce Protective unit excessive pressure, pass when flowing is it in charge of surface temperature to be too high and out of shape and catching fire to discharging;
Protective unit a, resistance of b line are smaller than 4¦¸, and too steady to change with temperature level , have reduced the impact on circuit pad control;
- Protect the improvement of the qualified rank
When the power line of 10¦¸¡¢ 220V (AC ) is touched , improve from qualified standard C grade for qualified standard B grade, and can output the warning signal ;
- Have long performance life
 FA9-220J3 type The extension of service life , has reduced the operating cost relatively. |
