current hogging การใช้

If multiple BJT transistors are connected in parallel ( which is typical in high current applications ), a current hogging problem can occur.
This can cause one MOV in a group to conduct more ( a phenomenon called current hogging ), leading to overuse and eventually premature failure of that component.
This technique can work well, but is susceptible to a phenomenon called "'current hogging "', in which the current is not shared equally across all devices.
Devices with an intrinsic positive temperature coefficient ( PTC ) of electrical resistance are less prone to current hogging, but thermal runaway can still occur because of poor heat sinking or other problems.
In power transistors ( which effectively consist of many small transistors in parallel ), current hogging can occur between different parts of the transistor itself, with one part of the transistor becoming more hot than the others.
