GS4B037681CBT Description

The GS4B037681CBT from TT Electronics/IRC is a high-precision 7.68K Ohm thin-film resistor network designed for demanding electronic applications. Housed in an 8-pin SOIC package with gull wing terminations, this ceramic-based network features 7 resistors in a BUS configuration, offering exceptional stability and accuracy with a tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient. Its 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating ensure reliable performance in compact, surface-mount designs. The SOIC package (4.9mm x 5.99mm x 1.45mm) with ±0.1mm length/height tolerances makes it suitable for high-density PCB layouts.

GS4B037681CBT Features

• Precision Thin Film Technology: Delivers high accuracy (±0.25%) and low TCR (±25ppm/°C) for stable performance across -70°C to +125°C.
• Robust Ceramic Case: Enhances thermal and mechanical durability compared to polymer-based networks.
• Optimized Power Handling: 0.4W total dissipation (0.05W/resistor) balances compact size with thermal efficiency.
• Automotive-Grade Alternatives: While not PPAP or automotive-qualified, its 125°C max operating temperature suits industrial and telecom applications.
• Strict Dimensional Tolerances: ±0.1mm (L/H) and ±0.2mm (D) ensure compatibility with automated SMT processes.

GS4B037681CBT Applications

• Signal Conditioning: Ideal for precision voltage dividers in ADC/DAC circuits.
• Industrial Controls: Stable performance in PLCs, sensor interfaces, and power management systems.
• Telecom Infrastructure: Reliable for RF matching networks and line termination.
• Test & Measurement Equipment: Low TCR minimizes drift in calibration circuits.

Conclusion of GS4B037681CBT

The GS4B037681CBT excels in applications requiring high precision, compactness, and thermal resilience. Its ceramic construction, tight tolerances, and thin-film technology provide a competitive edge over polymer-based networks, particularly in environments with wide temperature fluctuations. While not RoHS-compliant, it remains a robust choice for industrial and telecom designs where reliability outweighs regulatory constraints.
