Wire wound resistors make lower noise than carbon composition resistors. Their performance is well in overload conditions. they're reliable and versatile and may be used with DCand audio range. The disadvantage of wire wound resistors is that they're costly and can't be utilized in high-frequency equipment Better resistors can be made using a thin film process to deposit resistive material on the chip surface but that adds even more cost. That is sometimes done for high accuracy analog circuits such as the ladder network in some D/A converters. Not open for further replies
