GS7B028200GFT

GS7B028200GFT Description

The GS7B028200GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. Packaged in a 14-pin narrow SOIC (SOIC-C series), this bussed (BUS) network integrates 13 thin-film resistors, each with a 820Ω resistance value and a tight ±2% absolute tolerance (±1% ratio tolerance). Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -55°C to +125°C, with derated power handling up to 70–125°C. The 0.05W (1/20W) power rating per resistor and 0.7W total power rating make it suitable for low-power, high-density designs. The 100V maximum voltage rating and gull-wing termination enable reliable surface-mount assembly in compact layouts.

GS7B028200GFT Features

• Ceramic substrate for enhanced thermal stability and durability.
• Thin-film technology delivers precision and low noise.
• Bussed (BUS) topology simplifies circuit design by interconnecting resistors.
• 14-pin SOIC package (8.66mm × 5.99mm × 1.45mm) with ±0.1mm length/height tolerances for consistent PCB fit.
• Wide temperature range (-55°C to +125°C) with derated power up to 125°C.
• Low TCR (±50ppm/°C) minimizes resistance drift under thermal stress.
• RoHS non-compliant (contains lead), suitable for legacy or specialized applications.

GS7B028200GFT Applications

Ideal for precision analog circuits, voltage dividers, and signal conditioning in:

• Industrial control systems requiring stable resistance under thermal cycling.
• Medical instrumentation where low noise and accuracy are critical.
• Telecommunications hardware (e.g., line drivers, filters) benefiting from bussed networks.
• Automotive test/validation setups (though not PPAP/AEC-Q200 qualified).
• Legacy equipment maintenance due to its robust ceramic construction.

Conclusion of GS7B028200GFT

The GS7B028200GFT stands out for its ceramic-based reliability, tight tolerances, and bussed design, offering a balance of precision and simplicity. While not suited for automotive or RoHS-compliant designs, its wide temperature range and low TCR make it a robust choice for industrial, medical, and telecom applications. Engineers will appreciate its drop-in compatibility with SOIC footprints and consistent performance in harsh environments.
