RT1200B7TR7

RT1200B7TR7 Description

The RT1200B7TR7 from CTS Resistor Products (a division of CTS Corporation) is a high-density 16-resistor network array designed for precision termination in compact electronic systems. Housed in a 32-pin LBGA package with dimensions of 8.00mm x 4.00mm (0.315" x 0.157"), this surface-mount device offers a 10Ω resistance per element with a ±5% tolerance and a ±200ppm/°C temperature coefficient. Part of the ClearONE™ series, it features a dual terminator circuit configuration, delivering 50mW power dissipation per resistor. The component is REACH compliant and rated MSL 1 (Unlimited) for moisture sensitivity, ensuring reliability in harsh environments.

RT1200B7TR7 Features

• High-Density Integration: 16 resistors in a compact LBGA package, optimizing PCB space.
• Stable Performance: Low ±200ppm/°C thermal drift ensures consistent operation across temperature ranges.
• Dual Terminator Design: Ideal for impedance matching in high-speed digital circuits.
• Robust Construction: 1.34mm (0.053") seated height suits low-profile applications.
• Tape & Reel (TR) Packaging: Enables automated assembly, reducing manufacturing costs.
• Obsolete Status: While discontinued, it remains a reliable choice for legacy systems like CompactPCI®.

RT1200B7TR7 Applications

This resistor network excels in termination, pull-up/pull-down, and voltage division tasks, particularly in:

• CompactPCI® backplanes for signal integrity management.
• Telecom infrastructure requiring precise impedance matching.
• Embedded systems with space constraints but demanding stable resistance values.
• Legacy industrial controls where repeatability and durability are critical.

Conclusion of RT1200B7TR7

The RT1200B7TR7 balances density, precision, and reliability, making it a standout for high-speed digital termination despite its obsolete status. Its low-profile, high-power handling (50mW/resistor), and automation-friendly packaging cater to demanding applications in telecom and embedded electronics. Engineers maintaining or designing legacy CompactPCI® systems will find this component indispensable for ensuring signal fidelity and system longevity.
