RT1400B7PTR7

RT1400B7PTR7 Description

The RT1400B7PTR7 from CTS Resistor Products (a division of CTS Corporation) is a high-density 18-resistor network array designed for precision termination in DDR SDRAM applications. Housed in a compact 27-pin LBGA package with dimensions of 9.00mm x 3.00mm (0.354" x 0.118"), this surface-mount device offers a dual-terminator circuit configuration with resistances of 25Ω and 50Ω at a tight ±1% tolerance. Its ±200ppm/°C temperature coefficient ensures stable performance across varying thermal conditions, while the 50mW power rating per element supports reliable operation in high-speed memory systems.

RT1400B7PTR7 Features

• High Integration: Combines 18 resistors in a space-saving LBGA package, reducing PCB footprint.
• Precision Performance: ±1% tolerance and low TCR (±200ppm/°C) for consistent signal integrity.
• DDR-SDRAM Optimized: Dual-terminator design minimizes signal reflection in memory buses.
• Robust Construction: MSL 1 (Unlimited) moisture sensitivity and REACH Unaffected compliance ensure reliability.
• Efficient Packaging: Supplied in Tape & Reel (TR) for automated assembly.

RT1400B7PTR7 Applications

Ideal for high-speed digital systems, the RT1400B7PTR7 excels in:

• DDR2/DDR3/DDR4 SDRAM modules for precise bus termination.
• Server/workstation memory interfaces requiring low-ESR, high-frequency stability.
• Embedded computing designs where space and signal fidelity are critical.
• Automotive/industrial electronics needing robust, temperature-resistant components.
