GS4B026490BT Description

The GS4B026490BT 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 649Ω resistance value with an ultra-tight ±0.1% tolerance, this ceramic-based thin-film network ensures exceptional stability and accuracy. Its SOIC-C series construction offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations, ideal for space-constrained PCB designs. The device operates over a -55°C to +125°C range (derated to 70°C–125°C) with a ±50ppm/°C temperature coefficient, making it suitable for environments requiring minimal drift. Rated for 100V maximum voltage and 0.4W total power dissipation, it balances performance with robustness.

GS4B026490BT Features

• Precision Thin Film Technology: Delivers ±0.1% tolerance and low TCR (±50ppm/°C) for critical analog/digital circuits.
• Bussed Network Design: Simplifies PCB layout with shared connections (BUS circuit designator).
• High-Temperature Resilience: Ceramic case and 125°C max operating temperature ensure reliability in harsh conditions.
