GS8B034991FDT Description

The GS8B034991FDT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 16-pin narrow SOIC package, this bussed (BUS) configuration device integrates 15 thin-film resistors, each with a 4.99KΩ resistance and a tight ±1% absolute tolerance. Its ±25ppm/°C temperature coefficient ensures minimal resistance drift across a broad operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The SOIC-C series construction features a rectangular ceramic case with gull-wing terminations, optimized for surface-mount assembly. With a 0.8W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances performance and reliability in compact designs.

GS8B034991FDT Features

• Precision Thin-Film Technology: Delivers stable ±0.5% ratio tolerance for matched resistor performance.
• Robust Ceramic Package: Enhances thermal stability and mechanical durability in harsh conditions.
• High-Density Integration: 15 resistors in a 9.91mm × 5.99mm footprint, ideal for space-constrained PCBs.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power up to 125°C.
• Automotive-Grade Alternatives: While not PPAP-certified, its ±0.1mm height tolerance and 1.27mm terminal pitch suit industrial and instrumentation use.
• Non-RoHS Compliant: For applications exempt from lead-free requirements.

GS8B034991FDT Applications
