GS4B021211BBT Description

The GS4B021211BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 7-resistor BUS-configuration array offers a 1.21KΩ resistance value per resistor with an exceptional ±0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Housed in a ceramic SOIC-8 package, it features gull-wing SMD terminations for reliable surface-mount assembly. With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it operates reliably in environments up to 125°C. The EU RoHS non-compliant designation should be noted for regulatory considerations.

GS4B021211BBT Features

• Precision Performance: Ultra-tight 0.1% tolerance and ±50ppm/°C TCR for stable operation in precision circuits.
• Robust Construction: Ceramic substrate and thin-film technology ensure durability and long-term reliability.
• Space-Efficient: Compact SOIC-8 package (4.9mm × 5.99mm × 1.45mm) with 1.27mm pitch for high-density PCB layouts.
• High-Temperature Capability: Rated for 125°C continuous operation, with derated power up to 70–125°C.
