The BMF provides an inher ently low and predictable Temperature Coefficient of Resistance (TCR) and excellent load life stability for high precision analog applications. Model VSH offers low TCR, excellent load life stability, tight tolerance, excellent shelf life stability, low current noise and low voltage coefficient, all in the same resistor. Our application engineering department is available to advise and make recommendations. For non-standard technical requirements and special applications, please contact us using the e-mail address in the footer below.
