GS4B018451GT

GS4B018451GT Description

The GS4B018451GT 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 resistance values and compact form factors. This ceramic-based thin-film resistor network offers a 8.45KΩ resistance per element with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring reliable performance across a -70°C to +125°C operating range. With a 0.05W (1/20W) power rating per resistor and a 100V maximum voltage rating, it is engineered for surface-mount (SMD) applications in demanding environments. The SOIC-C series construction provides robust mechanical stability, while the gull-wing termination ensures secure PCB mounting.

GS4B018451GT Features

• Bussed Network Design: 7 resistors connected in a common bus configuration for simplified circuit routing.
• High-Temperature Stability: Operates reliably up to 125°C with derated power handling.
• Precision Thin-Film Technology: Delivers low TCR (±100ppm/°C) and ±2% tolerance for accuracy-critical designs.
• Compact & Robust: 4.9mm × 5.99mm × 1.45mm ceramic SOIC package with ±0.1mm height/length tolerances.
• Automotive-Grade Alternatives: While not PPAP/automotive-certified, its wide temperature range suits industrial and telecom applications.
• High Voltage Handling: 100V rating per resistor, ideal for signal conditioning and divider networks.
