RT1300B6

RT1300B6 Description

The RT1300B6 from CTS Corporation is a high-precision surface-mount resistor network designed for LVD SCSI (Low Voltage Differential Small Computer System Interface) applications. Part of the ClearONE™ series, this 27-resistor array integrates a dual terminator circuit with a compact footprint of 11.43mm x 5.08mm (0.450" x 0.200") and a low-profile height of 1.47mm (0.058"). It offers a ±1% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance in demanding environments. With a 50mW power rating per element and 121Ω/475Ω resistance values, it is optimized for signal integrity in high-speed data transmission systems.

RT1300B6 Features

• 27-Pin BGA Package: Ideal for dense PCB layouts, providing space efficiency and reliable connectivity.
• Dual Terminator Circuit: Reduces signal reflection and noise in LVD SCSI applications.
• High Precision: ±1% tolerance and ±200ppm/°C TCR ensure consistent performance across temperature variations.
• Low-Profile Design: 1.47mm seated height suits slimline and space-constrained designs.
• Bulk Packaging: Facilitates automated assembly processes, improving manufacturing efficiency.
• Moisture Sensitivity Level 1 (Unlimited): No baking required before use, simplifying storage and handling.

RT1300B6 Applications

The RT1300B6 excels in high-speed data communication systems, particularly:

• SCSI Terminations: Ensures signal integrity in enterprise storage systems and server backplanes.
• Network Equipment: Used in routers, switches, and other devices requiring precise impedance matching.
• Industrial Electronics: Suitable for automation controls and instrumentation due to its robust tolerance.
• Obsolete but Legacy-Compatible: While marked obsolete, it remains critical for maintaining legacy LVD SCSI infrastructure.

Conclusion of RT1300B6

The RT1300B6 resistor network combines precision, compactness, and reliability, making it a standout choice for LVD SCSI terminations and other high-speed signal applications. Its dual terminator design, tight tolerance, and low-profile form factor address key challenges in modern electronics, though designers should note its obsolete status and plan for alternatives in new designs. For legacy systems, it remains a high-performance solution from CTS’s proven ClearONE™ series.
