RT1400B7TR13

RT1400B7TR13 Description

The RT1400B7TR13 from CTS Corporation is a high-precision 18-resistor network designed for DDR SDRAM termination applications. Housed in a compact 27-pin LBGA package, it features a dual-terminator circuit with resistances of 25Ω and 50Ω, ensuring optimal signal integrity in high-speed memory systems. With a ±1% tolerance and ±200ppm/°C temperature coefficient, this device delivers stable performance across varying environmental conditions. Its ultra-low profile (1.34mm max height) and surface-mount design make it ideal for space-constrained PCB layouts. The product is REACH unaffected and complies with EAR99 export controls, though it is currently marked as obsolete.

RT1400B7TR13 Features

• 18 resistors in a single 9.00mm x 3.00mm package, saving board space.
• Dual-termistor circuit for precise DDR SDRAM termination, reducing signal reflections.
• ±1% tolerance and ±200ppm/°C thermal stability for reliable operation.
• 50mW power rating per element, suitable for low-power applications.
• MSL 1 (Unlimited) moisture sensitivity, easing handling and storage.
• Tape & Reel (TR) packaging for automated assembly efficiency.
• Part of the ClearONE™ series, known for high-density integration.

RT1400B7TR13 Applications

• DDR memory modules: Ensures clean signal termination in high-speed data buses.
• Server and workstation motherboards: Minimizes crosstalk and EMI in dense layouts.
• Embedded systems: Compact footprint suits space-limited designs.
• Networking equipment: Provides stable termination for high-frequency signals.

Conclusion of RT1400B7TR13

The RT1400B7TR13 excels in high-speed memory applications with its precision resistors, compact form factor, and robust thermal performance. While obsolete, its ClearONE™ technology and dual-termination capability make it a legacy solution for DDR-based systems requiring reliable signal integrity. Engineers should evaluate alternative CTS offerings for new designs but may consider this model for legacy maintenance or specific use cases.
