GS4B021400JT

GS4B021400JT Description

The GS4B021400JT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) package, designed for precision applications requiring stable thin-film resistance. With a 140Ω resistance value and ±5% tolerance, it ensures reliable performance in demanding circuits. The ceramic case construction enhances thermal stability, supporting operation from 70°C to 125°C at derated power. Its ±50ppm/°C temperature coefficient minimizes resistance drift, while the 100V maximum voltage rating and 0.4W total power dissipation (0.05W per resistor) suit compact, power-sensitive designs.

GS4B021400JT Features

• Bussed Network: 7 resistors connected in a bus configuration, simplifying PCB layout for common-node applications.
• Thin Film Technology: Delivers low noise and high stability compared to thick-film alternatives.
• Robust Packaging: Ceramic SOIC-C case ensures durability and efficient heat dissipation.
• Precision Tolerance: ±5% absolute tolerance and tight ±0.1mm length/height tolerances for consistent placement.
• Wide Temperature Range: Operates up to 125°C, ideal for industrial environments.
• Gull Wing Termination: Facilitates reliable surface mounting with 1.27mm pitch.

GS4B021400JT Applications

This resistor network excels in:

• Voltage Divider Circuits: Stable resistance values ensure accurate signal conditioning.
• Bus Termination: Protects high-speed digital lines (e.g., SPI, I2C) from reflections.
• Industrial Controls: Withstands harsh conditions in motor drives or PLCs.
• Automotive Electronics (Non-Automotive Rated): Auxiliary systems where EU RoHS compliance isn’t mandatory.
• Compact Consumer Electronics: Space-constrained designs like wearables or IoT modules benefit from its 4.9mm × 5.99mm footprint.

Conclusion of GS4B021400JT

The GS4B021400JT combines ceramic durability, thin-film precision, and bussed topology to address challenges in signal integrity and space efficiency. While not PPAP or automotive-qualified, its 125°C rating and low TCR make it a versatile choice for industrial, telecom, and consumer applications. Engineers will appreciate its balance of performance and cost in high-density PCBs requiring reliable passive networks.
