RT1402B6TR7

RT1402B6TR7 Description

The RT1402B6TR7 is an 18-resistor network array from CTS Resistor Products' ClearONE™ series, designed for high-performance termination in DDR SDRAM applications. This surface-mount device (SMD) features a compact 27-pin LBGA package with dimensions of 11.43mm x 3.81mm (0.450" x 0.150") and a low profile of 1.47mm (0.058"), making it suitable for space-constrained PCB designs. Each resistor in the array offers a 50Ω resistance with a tight ±1% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying operating conditions. The dual-terminator circuit configuration and 50mW power rating per element enhance signal integrity in high-speed memory interfaces.
