RT2405B7TR13

RT2405B7TR13 Description

The RT2405B7TR13 from CTS Resistor Products is a high-performance 18-resistor network in a compact 36-pin LBGA package, designed for precision termination in DDR SDRAM applications. With a 22Ω resistance per element and a tight ±1% tolerance, this dual-terminator network ensures signal integrity in high-speed memory interfaces. Its ±200ppm/°C temperature coefficient and 50mW power rating per resistor provide stable performance under varying thermal conditions. The 0.354" x 0.157" (9.00mm x 4.00mm) footprint and 1.34mm profile make it ideal for space-constrained designs.
