GS4B034702GT

GS4B034702GT Description

The GS4B034702GT 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. This ceramic-based resistor network offers a 47KΩ resistance per element with a tight ±2% tolerance and an ultra-low ±25ppm/°C temperature coefficient, ensuring minimal drift across its operating range of -70°C to +125°C. Rated for 100V maximum voltage and 0.4W total power dissipation, it features gull-wing terminations for reliable surface-mount (SMD) assembly. The SOIC-C series construction provides robust mechanical stability, with dimensions of 4.9mm (L) × 5.99mm (D) × 1.45mm (H) and tight tolerances (±0.1mm height/length).

GS4B034702GT Features

• Bussed Network Design: 7 resistors connected to a common bus, simplifying PCB layout in voltage-divider or pull-up/down circuits.
• Thin-Film Technology: Delivers superior accuracy (±2%) and low TCR (±25ppm/°C) vs. thick-film alternatives.
• High-Temperature Resilience: Operates at derated power up to 125°C, ideal for harsh environments.
• Compact SOIC Package: Space-saving 8-pin narrow SOIC (1.27mm pitch) with ceramic substrate for thermal stability.
• Automation-Friendly: Tube packaging ensures compatibility with pick-and-place systems.
• Non-Automotive/Non-PPAP: Suitable for industrial, telecom, and instrumentation (not automotive-qualified).

GS4B034702GT Applications

• Precision Voltage Division: Used in ADC/DAC reference circuits due to low TCR and matched resistance.
• Signal Conditioning: Ideal for sensor interfaces where stability across temperature is critical.
• Pull-Up/Down Networks: Simplifies bus termination in digital systems (e.g., I²C, SPI).
• Industrial Controls: Reliable performance in PLCs, power supplies, and test equipment.
• Telecom Hardware: Compact footprint suits high-density PCBs in routers/switches.

Conclusion of GS4B034702GT

The GS4B034702GT excels in applications demanding high precision, thermal stability, and space efficiency. Its thin-film ceramic construction and bussed architecture reduce component count while maintaining performance, outperforming generic thick-film networks. Though not RoHS-compliant or automotive-grade, it’s a cost-effective choice for industrial and telecom systems where reliability under thermal stress is paramount. Engineers should verify compatibility for mission-critical designs due to its "Unconfirmed" part status.
