Product Description
CR Series General Purpose Thick Film Resistors
Product Overview
The CR Series General Purpose Thick Film Resistors are designed for a wide range of applications, offering stable performance over temperature and good power dissipation capabilities. Constructed with an alumina substrate and featuring a tin plating over nickel termination, these resistors ensure excellent solderability. They are available in various sizes from 01005 to 2512 and offer TCR as low as 100ppm. Some values are also available for conductive epoxy applications, making them suitable for specialized uses like MRI applications.
