That small a value, from my experience, will be hard to find by salvaging a component. You'd also need to know its wattage rating.Where can I salvage an equivalent resistor? This was for the power supply circuit for an LCD
No way to know without a schematic of the circuit it is (or was) in when it failed - if that's what happened.How much difference in ohm can I get away with?
Thanks.My guess is a 0.22 Metal Oxide resistor, http://www.digikey.com/product-search/en/resistors/through-hole-resistors/66690?k=.22+metal+oxide&k=&pkeyword=.22+metal+oxide&pv1=1327&FV=fff40001,fff80482&mnonly=0&newproducts=0&ColumnSort=0&page=1&quantity=0&ptm=0&fid=0&pageSize=25 on the order of 1 W.
Metal oxide resistors are typically used as safety resistors because they usually vaporize. Metal film resistors tend to puddle. If it's wire wound resistor, you should be able to tell. The other types are carbon film and carbon composition.
Each has an intended use and carbon composition is the lowest cost.
