GS8B034992DDT Description

The GS8B034992DDT is a high-precision ceramic resistor network from TT Electronics/IRC, designed for demanding applications requiring stable performance under varying thermal conditions. This 16-pin Narrow SOIC (SOIC-C Series) device integrates 15 bussed resistors with a 49.9KΩ resistance value, offering an absolute tolerance of ±0.5% and a ratio tolerance of ±0.5%. Its thin-film technology ensures low noise and high accuracy, while the ±25ppm/°C temperature coefficient guarantees minimal resistance drift across a wide operating range of -70°C to +125°C. The 0.05W (1/20) power rating per resistor and 100V maximum voltage rating make it suitable for precision analog and digital circuits.

GS8B034992DDT Features

• High Precision: Tight tolerances (±0.5%) and low TCR (±25ppm/°C) ensure reliable performance in critical applications.
• Robust Construction: Ceramic case and gull-wing termination provide mechanical durability and ease of surface-mount assembly.
• Space-Efficient: Compact SOIC package (9.91mm × 5.99mm × 1.45mm) with a 1.27mm terminal pitch optimizes PCB real estate.
• Thermal Stability: Operates reliably up to 125°C, with derated power handling up to 70°C–125°C.
• Bussed Configuration: Simplifies circuit design by connecting multiple resistors to a common node (BUS designator).

GS8B034992DDT Applications

This resistor network is ideal for:

• Precision Voltage Dividers: Used in sensor interfaces and ADC/DAC circuits where ratio matching is critical.
• Industrial Electronics: Suitable for harsh environments due to its ceramic construction and wide temperature range.
• Medical Devices: Low noise and high accuracy support sensitive instrumentation.
• Automotive Systems (non-Automotive PPAP): Engine control units (ECUs) and infotainment systems benefit from its stability.
• Telecommunications: Signal conditioning and impedance matching in RF and baseband circuits.
