GS4B0190R9GT

GS4B0190R9GT Description

The GS4B0190R9GT from TT Electronics/IRC is a high-reliability 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable performance under varying conditions. Featuring a 90.9Ω resistance per element with a tight ±2% tolerance and a ±100ppm/°C temperature coefficient, this ceramic-based thin-film resistor network ensures consistent operation across a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C. Its 0.05W (1/20) power rating per resistor and 0.4W total power handling make it suitable for low-power circuits, while the 100V maximum voltage rating enhances versatility in signal conditioning and voltage division applications.

GS4B0190R9GT Features

• Ceramic substrate for superior thermal stability and durability.
• Bussed (BUS) configuration simplifies circuit design by interconnecting resistors.
• Thin-film technology delivers low noise and high precision.
• Gull-wing termination ensures reliable surface-mount (SMD) compatibility.
• Compact SOIC package (4.9mm × 5.99mm × 1.45mm) with tight tolerances (±0.1mm length/height, ±0.2mm depth).
• Non-automotive (PPAP: No) but ideal for industrial and telecom applications.
• Non-RoHS compliant, suitable for legacy or specialized designs.

GS4B0190R9GT Applications

This resistor network excels in:

• Voltage dividers and pull-up/down circuits in embedded systems.
• Signal conditioning for sensors and ADCs in measurement equipment.
• Bus termination in communication interfaces (e.g., I2C, SPI).
• Power supply feedback networks requiring stable resistance over temperature.
• Industrial control systems where ceramic construction resists environmental stress.

Conclusion of GS4B0190R9GT

The GS4B0190R9GT stands out for its precision, compact form factor, and robust ceramic construction, making it a preferred choice for engineers designing high-density PCBs or systems demanding thermal stability. While not automotive-grade, its 2% tolerance and bussed topology reduce component count in bus-oriented circuits, streamlining BOMs. Ideal for telecom, test equipment, and industrial electronics, this network balances performance with cost-effectiveness in non-RoHS applications.
