I am looking at TVS diodes suitable of passing the ISO16750-2 Load dump test A. For a 12v system 79V<Us<101v. Just to confirm the max voltage of the pulse can be from 79v not 79+Ua= 93 with Ua =14v
I am testing an output of a hall effect sensor using a wurth ferrite bead 742792662.
Testing to ISO11452-2 RF immunity,the immunity if 200Mz but passing at 400mhz upwards
I'm looking at the effect of ferrite bead on a pcb to improve Susepability when EMC testing.
Looking at the curves on the data sheets .
The peak resistance seems to be around the 2mhz range.
Does this mean the ferrite bead will filter out frequencys around this range ie the higher the...
Hi Zapper,
Yes I know they are too low. The reason for the circuit is I'm using a switch with a min wetting current of 10mA. the switch contacts are between R8and R9 . ,so i can make them a value that say delivers 20mA .
I was just playing with the values of R8 and R9 . I just...
Yes I'm using LTspice and it works perfectly on the simulation. I know there is no minimum source drain current , just wanted to confirm I'm not missing anythnig silly really.
I need to switch some ressitors into a resistance network, but this means I have a resistive load on my source as well as drain of the fet. Can I do this??
see attachment
I have a switch which specifes the minimum switching current is 10mA at 12VDC. Now my circuit switches 11mA at 5V.
Does the power need to match ie IxV 0.01 x 12 = 120mW or would the 11mA at 5v BE SUFFICIENT???
