PRN155

The PRN103/153/125/PRN155 is a high performance Integrated Passive Device (IPD) designed to eliminate transmission line effects on high-speed data lines on a special bus called SCSI (Small Computer Systems Interface). SCSI is a bus interface covered by an ANSI standard that allows for an input/output bus to connect small computers with a variety of peripheral devices.

Proper resistor termination requires a resistor PRN155 whose value closely matches the characteristic impedance of the transmission line. Thin film networks offer significant advantages over conventional thick film processes in terms of tighter absolute and ratio tolerances, greater stability, lower noise, and Temperature Coefficient of Resistance (TCR). Furthermore, they offer superior high frequency performance with minimal parasitic inductance and capacitance. Integrated thin film networks also offer the benefits of board space savings, reduced assembly costs, and increased reliability with fewer components.
