GS8A0228R7GT Description

The GS8A0228R7GT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a 16-pin SOIC ceramic package, it offers 28.7Ω resistance per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The isolated (ISOL) circuit design provides independent resistors, making it ideal for signal conditioning and impedance matching. With a 0.8W total power rating (0.1W per resistor) and 100V maximum voltage rating, this surface-mount device (SMD) is engineered for reliability in demanding environments. Its gull-wing termination ensures robust solder joints, while the ceramic case enhances thermal and mechanical durability.

GS8A0228R7GT Features

• Thin Film Technology: Delivers superior accuracy and stability compared to thick-film alternatives.
• Ceramic SOIC Package: Combines high thermal conductivity with compact dimensions (9.91mm x 5.99mm x 1.45mm).
• Isolated Resistors: Each of the 8 resistors operates independently, enabling flexible circuit designs.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power performance.
• Low TCR (±50ppm/°C): Minimizes resistance drift under thermal stress.
• Gull-Wing Termination: Facilitates automated PCB assembly and improves mechanical stress resistance.
• High Voltage Rating (100V): Suitable for industrial and automotive-grade applications (though not PPAP/automotive certified).
