Wat effect does temperature have on resistors and semiconducters?

Question

its a physic question

that the whole question no more to it.

plz plz help

Answer 1

Resistors, temperature coefficient depends on type.

.... thick film resistors are typically ±200 or ±250 ppm/K

.....thin film resistors 25 ppm/K

....metal film 25 or 50 ppm/K

Junction transistors, diodes

.....leakage goes up with temp, doubles every 10C

..........(applies to all semiconductors)

....VF goes down 2 mV per degree C

....HFE goes up with temperature
