RT2250B7TR7

RT2250B7TR7 Description

The RT2250B7TR7 from CTS Resistor Products (a division of CTS Corporation) is a high-performance 16-resistor network array designed for precision termination applications. Packaged in a compact 24-pin LBGA (0.315" x 0.118") with a low-profile 1.34mm height, this surface-mount component is optimized for space-constrained PCB designs. It features dual-termistor functionality with resistances of 82.5Ω and 127Ω at a tight ±1% tolerance, ensuring consistent signal integrity in high-speed circuits. The ±200ppm/°C temperature coefficient and 60mW/66mW power rating per element make it suitable for stable operation under varying thermal conditions.

RT2250B7TR7 Features

• ClearONE™ Series: Combines high-density integration with low parasitic effects for superior signal fidelity.
• Dual-Terminator Design: Supports LVPECL applications, reducing reflection and overshoot in high-speed differential lines.
• RoHS Compliance & MSL1: Environmentally friendly and suitable for unlimited shelf life with no baking requirements.
• Tape & Reel Packaging: Enables automated pick-and-place assembly, streamlining production efficiency.
• Obsolete Status: While no longer in active production, remaining stock is ideal for legacy system maintenance or long-lifecycle designs.

RT2250B7TR7 Applications

This resistor network excels in:

• High-Speed Communication: Termination for LVPECL interfaces in networking equipment, servers, and telecom infrastructure.
• Signal Conditioning: Impedance matching in FPGA/ASIC-based systems to minimize signal degradation.
• Embedded Systems: Dense PCB layouts requiring reliable, low-profile passive arrays with minimal footprint.
• Legacy Upgrades: Replacement or repair of aging hardware where original specifications must be maintained.

Conclusion of RT2250B7TR7

The RT2250B7TR7 offers a robust solution for precision termination, balancing compactness, thermal stability, and electrical performance. Its dual-resistance values and LVPECL optimization make it stand out for high-speed digital designs, though its obsolete status necessitates inventory planning for future needs. Engineers valuing low parasitics, tight tolerances, and automated assembly compatibility will find this component a reliable choice for critical signal integrity applications.
