GS8A021273CBT

GS8A021273CBT Description

The GS8A021273CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 127K Ohm resistance per element with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin SOIC package with gull-wing SMD termination, it offers excellent electrical isolation (ISOL circuit designator) and mechanical durability due to its ceramic case construction. With a 0.8W total power rating (0.1W per resistor) and 100V maximum voltage rating, it is ideal for precision analog and mixed-signal circuits.

GS8A021273CBT Features

• High Precision: ±0.25% tolerance and ±50ppm/°C TCR for stable performance in critical applications.
• Robust Construction: Ceramic case and thin-film technology ensure reliability under thermal stress.
• Space-Efficient: Compact SOIC-16 package (9.91mm × 5.99mm × 1.45mm) with 1.27mm terminal pitch for high-density PCB layouts.
• Isolation-Centric Design: ISOL circuit configuration minimizes crosstalk in multi-channel systems.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C for high-temperature environments.
• Surface-Mount Compatibility: Gull-wing termination facilitates automated assembly processes.

GS8A021273CBT Applications

• Industrial Automation: Precision voltage dividers and sensor signal conditioning in harsh environments.
• Medical Electronics: Isolation networks for patient monitoring equipment requiring high accuracy.
• Telecommunications: Impedance matching and filtering in RF and baseband circuits.
• Test & Measurement: Calibration references and analog front-end networks.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical systems where precision is key.

Conclusion of GS8A021273CBT

The GS8A021273CBT excels in applications demanding high precision, thermal stability, and electrical isolation. Its ceramic SOIC package, thin-film technology, and ISOL design make it superior to standard epoxy-coated networks, particularly in environments with thermal cycling or stringent accuracy requirements. While not PPAP or automotive-qualified, it is a cost-effective solution for industrial, medical, and telecom systems where reliability and performance are critical.
