PRN111

CAMDs PRN101/111 Bussed Resistor Termination Networks offer high integration and performance in a miniature QSOP or SOIC package, which saves critical board area and provides manufacturing cost and reliability efficiencies. This part is well-suited as a general purpose replacement for all popular MLCC resistor chips and larger size thick film technology packages.

Why thin film resistor networks? A terminating resistor is used to reduce or eliminate unwanted reflections on atransmission line or in some cases provide DC pull-up/ pull-down. It can perform this function only when its resistance value is closely matched to the characteristic impedance of the transmission line. The resistors used for terminating transmission lines must be noiseless, stable, and functional at high frequencies. Unlike thin film-based resistor networks, conventional thick film resistors used for this purpose are not as stable over temperature and time, and may have functional limitations when used in high frequency applications.
