GS7A0226R1GGT

GS7A0226R1GGT Description

The GS7A0226R1GGT 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 resistance values under varying thermal conditions. Featuring a 26.1Ω resistance per element with a tight ±2% absolute tolerance and ±2% ratio tolerance, this thin-film ceramic-based network ensures reliable performance in demanding environments. Its ±50ppm/°C temperature coefficient minimizes resistance drift across the -70°C to +125°C operating range, while the 100V maximum voltage rating and 0.1W power rating per resistor (0.7W total) make it suitable for low-power, high-voltage circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration.

GS7A0226R1GGT Features

• Isolated Resistor Network: 7 independent thin-film resistors in a single SOIC package, reducing board space and simplifying design.
• High Stability: Ceramic substrate and thin-film technology ensure low TCR (±50ppm/°C) and long-term reliability.
• Precision Tolerance: ±2% absolute and ratio tolerance for consistent performance in matched circuits.
• Robust Construction: SOIC-C series ceramic case offers superior thermal and mechanical durability vs. polymer-based networks.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power, ideal for industrial and automotive (non-AEC-Q200) applications.
• Compact Dimensions: 8.66mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).

GS7A0226R1GGT Applications

• Voltage Dividers & Sensor Interfaces: Precision resistance matching for ADC/DAC reference circuits.
• Isolation Circuits: Signal conditioning in medical or industrial isolation barriers.
• Power Supply Feedback Networks: Stable feedback loops in DC/DC converters.
• Test & Measurement Equipment: High-accuracy instrumentation requiring low drift.
• Aerospace & Defense: Reliable performance in extended temperature environments (note: non-PPAP).
