i was going to use the 2W 0.1ohm carbon film resistor as load balancing in parallel mosfets working in linear region (emitter follower, or "source" follower). but after reading the net and here, the weight is more heavy on the answer that the jelly-bean resistor is a NTC, so its not suitable for the job. hence i ditch out the idea of load balancing and just connect the mosfets source pin together. thanks all guys for your reply.
