GS4B027681DDT Description

The GS4B027681DDT from TT Electronics/IRC is a high-precision 7.68K Ohm thin-film resistor network designed for surface-mount (SMD) applications. Housed in an 8-pin SOIC package with gull-wing terminations, this ceramic-based network features 7 resistors in a BUS configuration, offering a tight tolerance of ±0.5% and a low ±50ppm/°C temperature coefficient. With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it operates reliably across a 70°C to 125°C derated temperature range. The rectangular package (4.9mm x 5.99mm x 1.45mm) ensures compatibility with automated assembly processes.

GS4B027681DDT Features

• Precision Performance: 0.5% tolerance and ±50ppm/°C TCR ensure stability in demanding circuits.
• Robust Construction: Ceramic case and thin-film technology provide excellent thermal and electrical reliability.
• Space-Efficient: Compact SOIC-8 footprint (4.9mm length) suits high-density PCB designs.
• Automation-Friendly: Gull-wing leads and ±0.1mm length/height tolerances enable precise placement.
• Wide Voltage Range: Supports up to 100V, ideal for industrial and instrumentation use.
• Non-Automotive: Compliant with EAR99 (ECCN) but not PPAP/automotive-grade.

GS4B027681DDT Applications

• Signal Conditioning: Precision voltage dividers in DAQ systems and sensor interfaces.
• Medical Electronics: Stable resistance networks for patient monitoring equipment.
• Test & Measurement: High-accuracy circuits in calibration instruments and multimeters.
• Industrial Controls: PLC modules and process controllers requiring low-drift performance.
• Communications: Impedance matching in RF front-end circuits (non-extreme environments).

Conclusion of GS4B027681DDT

The GS4B027681DDT excels in applications demanding precision, compactness, and thermal stability. Its ceramic SOIC package and thin-film resistors offer superior performance over thicker-film networks, while the BUS configuration simplifies circuit design. Though not RoHS-compliant or automotive-rated, it remains a cost-effective choice for industrial, medical, and test equipment where accuracy and reliability are critical. Engineers should verify unconfirmed status for production use.
