Abstract

Standard inductors manufactured by General Radio (GR) are widely used by NMIs. The temperature coefficient for these standard inductors is 30 ± 5 ppm/°C, as per manufacturer. NPL India (NPLI) had earlier determined the temperature coefficient of standard inductors by measuring change in inductance. Now by measuring change in resistance, temperature coefficient of inductors is re-determined. Temperature coefficients determined from the two methods are reported here.

通过测量电感和电阻的变化比较标准电感的温度系数

通用无线电公司(GR)生产的标准电感器被nmi广泛使用。根据制造商的要求，这些标准电感器的温度系数为30±5 ppm/°C。印度国家物理研究所(NPLI)早些时候通过测量电感的变化来确定标准电感的温度系数。现在，通过测量电阻的变化，可以重新确定电感器的温度系数。这里报告了用这两种方法确定的温度系数。
