Product Description
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 a
transmission 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 limita-
tions when used in high frequency applications.

California Micro Devices can develop a fully customized solution which embodies the configuration shown in this data sheet or modified to
suit specific application requirements. Very precise TCR, TCR tracking and resistor tolerances, and resistor-to-resistor ratio matching can
also be provided. A Non-Recurring Engineering (NRE) charge will apply for all fully customized requirements and a minimum order/lot will be
required.
Please direct your detailed circuit configuration and specification requirements to your local CAMD representative or to the factory for a
quotation.
