GS4B021150JDT

GS4B021150JDT Description

The GS4B021150JDT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. With a 115Ω resistance value (±5% tolerance) and ±50ppm/°C temperature coefficient, it ensures reliable performance across a 70°C to 125°C operating range. The ceramic substrate enhances thermal stability, while the gull-wing termination facilitates robust surface-mount assembly. Rated for 100V maximum voltage and 0.4W total power dissipation, this network is ideal for compact, high-density PCB designs.

GS4B021150JDT Features

• Bussed Network Design: Simplifies circuit layout with a shared common terminal (BUS) for streamlined signal routing.
• Thin-Film Technology: Delivers superior accuracy (±5% absolute, ±0.5% ratio tolerance) and low noise.
• High-Temperature Resilience: Operates up to 125°C with derated power handling.
• Mechanical Robustness: Ceramic case and SOIC package ensure durability in harsh environments.
• Space-Efficient: Compact dimensions (4.9mm × 5.99mm × 1.45mm) with tight tolerances (±0.1mm height/length).
• Automation-Friendly: Tube packaging and 1.27mm pitch enable efficient pick-and-place assembly.

GS4B021150JDT Applications

• Voltage Division & Pull-Up/Down Circuits: Optimized for bus termination in digital systems (e.g., I²C, SPI).
• Sensor Signal Conditioning: Stable resistance for precision analog front-ends in industrial sensors.
• Power Management Modules: Used in DC-DC converters and load-sharing networks due to low TCR.
• Automotive & Industrial Electronics: Suitable for non-automotive applications requiring thermal endurance (e.g., motor drives, HVAC controls).

Conclusion of GS4B021150JDT

The GS4B021150JDT excels in high-reliability, space-constrained designs where stable resistance and thermal performance are critical. Its ceramic construction, thin-film accuracy, and bussed topology offer distinct advantages over polymer-based networks, particularly in industrial and communication systems. While not PPAP or RoHS compliant, it remains a cost-effective solution for non-automotive precision circuits. Engineers should evaluate its 5% tolerance against application requirements, though the ±0.5% ratio tolerance ensures consistency across matched resistors.
