Product Description
The PAC™RPI series terminator network offers highperformance, high reliability, and low cost throughmanufacturing efficiency. The resistor termination
elements are fabricated using state-of-the-art thin filmmanufacturing. The resistor elements are specified at1% tolerance for the most demanding termination
requirements. This integrated solution† is silicon-based
and has the same reliability characteristics as any oftoday’s microprocessor products. The thin film resistorshave excellent stability over temperature, applied
voltage, and product life. In addition, the QSOP industrystandard packaging is easy to handle in manufacturingand provides interconnect reliability on par with othercommon semiconductor components.
