線繞電阻的線材直接決定了電阻的溫飄和阻值的大小，也影響電阻的短時(shí)過(guò)載能力和阻值的長(zhǎng)期穩(wěn)定性。

鎳鉻合金是最常用的線材，但各個(gè)線材供應(yīng)廠家的質(zhì)量和工藝千差萬(wàn)別，合金中微量元素的成份也不盡相同。

高質(zhì)量的線材在高溫?zé)Y(jié)的過(guò)程中電性能變化很少，質(zhì)量穩(wěn)定。

同樣大小的基體繞制不同等級(jí)的線材所得到的阻值范圍差別很大。這就是為什么同等功率的線繞電阻，國(guó)內(nèi)廠家往往只能做到千歐級(jí)別，國(guó)外廠家可以做到上百千歐甚至幾十兆歐姆。不同的阻值，不同的功率，需要選擇不同的線號(hào)。

盛雷城精密電阻有限公司使用優(yōu)質(zhì)的進(jìn)口特種合金絲上次高精密線繞電阻，阻值范圍大，溫度系數(shù)低，穩(wěn)定性高。

Thunder Precision Resistor Co., Ltd. make precision wire wound resistors with the high quality alloy wire imported to keep the high stablility of the precision wire wound resistors as well as high resistance range.

All resistors come with a tolerance value, which is given as a percentage. The tolerance value tells us how close to the nominal value a resistance can vary. For example, a 500? resistor that has a tolerance value of 10%, may have a resistance that is somewhere between 10% above 500? (550?) or 10% below 500? (450?). If the same resistor has a tolerance of 1%, its resistance will only vary by 1%. Therefore, a 500? resistor can then vary between 495? and 505?.

盛雷城精密電阻有限公司專業(yè)生產(chǎn)高精度電阻器，電阻精度高于0.1%，電阻穩(wěn)定性指標(biāo)高于0.05%
