GS4A034870GBT

GS4A034870GBT Description

The GS4A034870GBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 487Ω and a tight ±2% absolute tolerance. Its ±25ppm/°C temperature coefficient ensures minimal resistance drift across the operating range of -70°C to +125°C, making it suitable for demanding environments. The SOIC-C series construction offers excellent mechanical durability, with a compact footprint (4.9mm × 5.99mm × 1.45mm) and gull-wing termination for reliable surface-mount assembly.

GS4A034870GBT Features

• Isolated Resistor Network: Four independent resistors (487Ω each) with ±0.1% ratio tolerance for precision voltage division or signal conditioning.
• High-Temperature Stability: Operates up to 125°C with derated power (0.1W per resistor, 0.4W total).
• Robust Construction: Ceramic substrate and thin-film technology ensure low noise, high reliability, and 100V maximum voltage rating.
• Tight Tolerances: ±0.1mm length/height tolerances and ±0.2mm depth tolerance for consistent PCB placement.
• Non-Automotive, Non-PPAP: Ideal for industrial and commercial applications where automotive-grade certification is not required.

GS4A034870GBT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces in test/measurement equipment.
• Signal Isolation: Isolated signal paths in communication modules or mixed-signal PCBs.
• High-Temperature Environments: Industrial controls, power supplies, and aerospace systems where thermal stability is critical.
• Space-Constrained Designs: Compact SOIC package suits densely populated boards in medical devices or IoT hardware.
