GS4B032490BT

GS4B032490BT Description

The GS4B032490BT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring a 249Ω resistance value with an ultra-tight ±0.1% tolerance, this ceramic-based thin-film resistor network ensures exceptional stability and accuracy. Its ±25ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments requiring minimal drift. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in precision circuits.

GS4B032490BT Features

• Ceramic SOIC-C Series Construction: Offers superior thermal and mechanical stability compared to polymer-based networks.
• Bussed Circuit Design: Simplifies layout in bus-line applications, reducing component count.
• Thin-Film Technology: Delivers low noise and high precision, ideal for analog signal processing.
• Gull Wing Termination: Ensures robust surface-mount compatibility with a 1.27mm terminal pitch.
• Extended Temperature Range: Operates from 70°C to 125°C with derated power, suited for industrial and automotive (non-PPAP) applications.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).

GS4B032490BT Applications

This resistor network excels in:

• Precision Voltage Dividers: Critical in ADC/DAC reference circuits due to its ±0.1% tolerance.
• Bus Termination Networks: Minimizes signal reflection in high-speed data lines (e.g., CAN, SPI).
• Industrial Control Systems: Stable performance in harsh environments (e.g., PLCs, sensor interfaces).
• Test & Measurement Equipment: Low TCR ensures accuracy over temperature fluctuations.

Conclusion of GS4B032490BT

The GS4B032490BT stands out for its ceramic thin-film construction, bussed design, and military-grade precision, making it a superior choice over epoxy-based networks in high-reliability applications. While non-compliant with EU RoHS, its 0.1% tolerance and ±25ppm/°C TCR cater to niche markets where performance outweighs regulatory constraints. Ideal for engineers prioritizing miniaturization, stability, and repeatability in analog or mixed-signal designs.
