GS7A0178R7JGT Description

The GS7A0178R7JGT from TT Electronics/IRC is a high-performance 7-resistor isolated network in a 14-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. With a 78.7Ω resistance value and ±5% absolute tolerance, this ceramic-based network ensures reliable performance in demanding environments. Its isolated circuit design (ISOL) allows independent resistor operation, minimizing crosstalk. The device operates over a wide temperature range (-70°C to +125°C) with a ±100ppm/°C temperature coefficient, making it suitable for thermally variable conditions. Encased in a rectangular ceramic SOIC package, it offers robust mechanical stability and 0.7W total power dissipation (0.1W per resistor).

GS7A0178R7JGT Features

• High Precision: Thin-film technology ensures ±5% tolerance and ±2% ratio tolerance for matched resistance values.
• Robust Construction: Ceramic case and gull-wing termination provide durability and ease of surface-mount assembly.
• Thermal Stability: Operates at up to 125°C with derated power handling, ideal for high-temperature environments.
• Isolated Design: Seven independent resistors reduce interference in multi-channel circuits.
• Compact Form Factor: 8.66mm × 5.99mm × 1.45mm dimensions with tight tolerances (±0.1mm height/length) suit space-constrained PCBs.
• High Voltage Rating: Supports 100V maximum voltage, suitable for industrial and automotive-grade applications (though non-automotive PPAP).
