GS7B014990FBT Description

The GS7B014990FBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 14-pin narrow SOIC (SOIC-C series) device integrates 13 bussed resistors, each with a 499Ω resistance value and a tight ±1% absolute tolerance. Its thin-film technology ensures low noise and high stability, while the ±100ppm/°C temperature coefficient guarantees reliable performance across a wide operating range of 70°C to 125°C. The network is housed in a rectangular ceramic package with gull-wing terminations, making it ideal for surface-mount assembly. With a power rating of 0.7W (0.05W per resistor) and a maximum voltage rating of 100V, it balances compactness with robust electrical characteristics.

GS7B014990FBT Features

• High Precision: ±1% tolerance and ±0.1% ratio tolerance for accurate signal conditioning.
• Thermal Stability: ±100ppm/°C TCR ensures minimal resistance drift.
• Robust Construction: Ceramic case enhances durability and heat dissipation.
• Space-Efficient: Compact SOIC package (8.66mm × 5.99mm × 1.45mm) with 1.27mm terminal pitch.
• Bussed Design: Simplifies circuit layout by connecting multiple resistors to a common node (BUS).
• Wide Voltage Range: Supports up to 100V, suitable for industrial and automotive environments (though not PPAP/AEC-Q200 certified).
• Non-RoHS: May be preferred for legacy or high-reliability systems requiring leaded components.
