高精密電阻器是什么？

很多工程技術(shù)人員都認(rèn)為，精度高的電阻就是高精密電阻器，百度百科也錯(cuò)誤地收錄了這樣的信息，以至于以訛傳訛，誤導(dǎo)了大家。

What is high precision resistors? Almost all techniciens think the resistors with tight tolerance are high precision resistors. It is not correct since the real meaning of high precision resistors are the resistors with high stability since without stability the tolerance is meaningless!

High precision resistors are made by professional manufacturers instead of sorting by most manufacturers or dealers from normal resistors since there is no real requeset of stability for normal reistors!

高精密電阻器真正的定義應(yīng)該是具有高穩(wěn)定性的電阻器，高精密電阻器的電阻阻值精度可以是0.01%，0.05%， 甚至可以是1%，但是，高精密電阻器的穩(wěn)定性指標(biāo)不論其實(shí)際精度都是一樣的，不論是0.01%，0.05%， 甚至是1%，其年度漂移指標(biāo)都要小于50ppm！

盛雷城精密電阻有限公司生產(chǎn)制造的 EE 系列超高穩(wěn)定性金屬膜電阻器是使用高溫模壓封裝，絕緣性能和抗潮濕性能都很高，標(biāo)準(zhǔn)溫度系數(shù)測(cè)量溫度區(qū)間減少為 60 °C，如果需要零下溫度性能，則可以提供負(fù)溫溫度系數(shù)測(cè)試。溫度系數(shù)可到 ±2 PPM/°C，阻值覆蓋至 5 Ohm。提供給設(shè)計(jì)工程師的軍事合格品質(zhì)的精密電阻元器件。

金屬膜精密電阻 EE 系列是 Vishay，IRC，松下理想的替代元件，并提供更有競(jìng)爭(zhēng)力的價(jià)格和快速交貨服務(wù)。聯(lián)系我們與您的特定需求。
