GS7A011781DT

GS7A011781DT Description

The GS7A011781DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 7-resistor array features a 1.78KΩ resistance value per resistor with a tight 0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a 14-pin SOIC package with gull-wing SMD termination, it offers 0.7W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and mixed-signal circuits. The ceramic case style enhances thermal stability, while the isolated (ISOL) circuit design provides electrical separation between resistors.

GS7A011781DT Features

• High Precision: 0.5% tolerance and ±100ppm/°C TCR for accurate signal processing.
• Robust Construction: Ceramic substrate ensures durability and thermal performance.
• Space-Efficient: Compact 8.66mm × 5.99mm × 1.45mm SOIC package ideal for dense PCB layouts.
• Reliable Termination: Gull-wing leads enable secure surface mounting with a 1.27mm pitch.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power.
• Isolated Design: Independent resistors (ISOL configuration) for flexible circuit integration.
• Non-Automotive: Suitable for industrial and commercial applications (PPAP not required).

GS7A011781DT Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and DAC/ADC interfaces.
• Signal Isolation: Buffering and conditioning in sensor interfaces or communication systems.
• Medical Electronics: Patient monitoring equipment requiring stable, low-drift resistors.
• Test & Measurement: Calibration tools and instrumentation where accuracy is critical.
• Industrial Controls: PLCs and automation systems needing robust, temperature-resistant components.

Conclusion of GS7A011781DT

The GS7A011781DT excels in applications demanding high precision, thermal stability, and electrical isolation. Its thin-film technology, ceramic construction, and gull-wing SMD compatibility make it a superior choice over thicker-film or less stable alternatives. While not RoHS-compliant, it remains ideal for specialized industrial and commercial systems where performance outweighs regulatory constraints. Engineers will appreciate its balance of accuracy, power handling, and compact form factor, particularly in analog signal chains and isolation-critical designs.
