GS8A012872GT

GS8A012872GT Description

The GS8A012872GT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications requiring stable resistance values and reliable isolation. Encased in a ceramic SOIC-16 package, it features 28.7KΩ resistance per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring minimal drift across operating temperatures (70°C to 125°C). Rated for 0.1W per resistor (0.8W total), it supports 100V maximum voltage and employs gull-wing SMD termination for robust surface-mount assembly. The ceramic substrate enhances thermal stability, while the isolated circuit design (ISOL) prevents crosstalk, making it ideal for signal conditioning and voltage division in harsh environments.

GS8A012872GT Features

• Precision Thin Film Technology: Delivers stable, low-noise performance with ±100ppm/°C TCR.
• High Power Handling: 0.8W total dissipation (0.1W per resistor) in a compact 9.91mm × 5.99mm × 1.45mm footprint.
• Robust Construction: Ceramic case ensures superior thermal management and mechanical durability.
• Isolated Resistors: Independent circuits (ISOL) eliminate interference, critical for analog signal chains.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Automotive-Grade Alternatives: While not PPAP-certified, its 125°C rating suits industrial and telecom applications.

GS8A012872GT Applications

• Signal Conditioning: Precision voltage dividers in sensor interfaces (e.g., strain gauges, RTDs).
• Medical Electronics: Isolation networks for patient monitoring equipment.
• Industrial Controls: Feedback loops in PLCs and motor drives, where temperature stability is critical.
• Telecom Infrastructure: Impedance matching in RF modules and baseband circuits.
• Test & Measurement: Calibration circuits requiring low TCR and high voltage tolerance.

Conclusion of GS8A012872GT

The GS8A012872GT excels in high-reliability applications demanding precision, thermal resilience, and electrical isolation. Its ceramic SOIC package and thin film technology offer a competitive edge over polymer-based networks, particularly in high-temperature or noise-sensitive environments. While not RoHS-compliant or automotive-qualified, it remains a top choice for industrial, medical, and telecom designs where performance outweighs regulatory constraints. Engineers will appreciate its balance of power handling, stability, and compactness in space-constrained PCBs.
