High Frequency Chip Resistor Terminators IRC Advanced Film Division Wraparound termination with non-leaching Nickel barrier PFC HF Series • Long life self-passivating TaNFilm® element • Frequency performance characterized to 6GHz • Available in 0402, 0603, 0805 and 1206 chip sizes • Standard Sn/Pb and Pb-free terminations available Ultra stable Tantalum Nitride resistor film system The PFC-HF series of high frequency chip terminators are available in standard chip resistor sizes. Available in 0402, 0603, 0805 and 1206 chip sizes, the PFC-HF is a drop-in replacement for poorer performing standard size chips. With operation characterized to 6GHz, the PFC-HF series is suitable for RF and microwave transmission line termination as well as high speed digital line termination. Applications include SCSI bus termination, DDR memory termination, RF and microwave transmit and receive line terminations and general high speed transmission line termination.
