CR Series General Purpose Thick Film Resistors
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. These resistors feature an alumina substrate with a resistive layer and are available with standard 100% matte Tin (Sn) plating over Nickel, ensuring excellent solderability. Some values are also suitable for conductive epoxy applications, making them ideal for MRI environments. The series offers a broad range of sizes from 01005 to 2512, with TCR as low as 100ppm.
