PFC chip resistor series provides the high precision and ultra stable performance of tantalum nitride resistive
lm system in 0402, 0603, 0805 and 1206 sizes. The unique characteristics of the passivated tantalum nitride
film ensure long term life stability and reliability in most environments.
Qualified for resistance to sulfur bearing gases, the PFC series is an excellent solution for automotive and
heavy equipment applications where precision, exceptional reliability with anti-sulfuration characteristics
is imperative.
