RT2402B7TR7

RT2402B7TR7 Description

The RT2402B7TR7 from CTS Resistor Products (a division of CTS Corporation) is a high-performance 18-resistor network 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 features a dual-terminator circuit configuration, ensuring optimal signal integrity in high-speed memory systems. With a 50Ω resistance per element and a tight ±1% tolerance, it delivers consistent performance across demanding environments. The ±200ppm/°C temperature coefficient further enhances stability under thermal variations.

RT2402B7TR7 Features

• 18-resistor array with 50mW power rating per element, ideal for distributed power dissipation.
• RoHS compliant and REACH unaffected, meeting stringent environmental standards.
• Moisture Sensitivity Level (MSL) 1, suitable for unlimited floor life in humid conditions.
• ClearONE™ series design ensures low parasitic effects, critical for high-frequency applications.
• Tape & Reel (TR) packaging for automated assembly efficiency.
• Obsolete status may require alternative sourcing for new designs, but remains reliable for legacy systems.

RT2402B7TR7 Applications

• DDR SDRAM termination: Minimizes signal reflection and overshoot in memory modules.
• High-speed PCB designs: Provides impedance matching for data buses and clock lines.
• Embedded systems: Ensures signal integrity in compact, high-density layouts.
• Industrial electronics: Stable performance in temperature-varying environments.

Conclusion of RT2402B7TR7

The RT2402B7TR7 excels in precision termination for DDR memory systems, offering low tolerance, thermal stability, and compact form factor. While obsolete, its ClearONE™ technology and robust construction make it a preferred choice for legacy or niche applications requiring reliable resistor networks. Engineers should evaluate replacement options for future-proof designs but can leverage its proven performance in existing implementations.
