Product Overview
The TFCR Series Precision Thin Film Resistors are designed for high-performance applications requiring precise resistance values and excellent stability. These resistors offer TCR as low as 25ppm, superior noise characteristics compared to standard thick film resistors, and higher operating frequencies due to reduced parasitics. They meet reference standards of EIA and JIS C 5201-1, providing tolerances as low as 0.1%. The standard termination is 100% matte Tin over Nickel.
