GS4B033091CBT Description

The GS4B033091CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 7-resistor BUS-configuration network features a 3.09KΩ resistance value per resistor with an exceptional ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a ceramic SOIC-8 package, it offers 0.4W total power dissipation (0.05W per resistor) and operates reliably within a -70°C to +125°C temperature range, making it suitable for industrial and precision electronics.

GS4B033091CBT Features

• Precision Thin Film Technology: Delivers superior stability and accuracy (±0.25%) compared to thick-film alternatives.
• Robust Ceramic Package: Enhances thermal performance and durability in harsh environments.
• High Voltage Rating: Supports up to 100V, ideal for signal conditioning and voltage division.
• Gull Wing Termination: Ensures reliable surface-mount (SMD) compatibility with a 1.27mm pitch for automated assembly.
• Low TCR (±25ppm/°C): Minimizes resistance variation under thermal stress, critical for precision analog circuits.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm) for space-constrained designs.

GS4B033091CBT Applications

This resistor network excels in:

• Analog Signal Processing: Precision dividers, feedback networks in op-amp circuits.
• Industrial Control Systems: Sensor calibration, PLCs, and instrumentation requiring long-term stability.
• Automotive Electronics: Despite non-automotive PPAP status, its 125°C rating suits under-hood modules (if RoHS compliance is not mandated).
• Medical Equipment: Low-noise, high-reliability signal paths in diagnostic devices.
• Test & Measurement: Reference circuits where tolerance and TCR are critical.

Conclusion of GS4B033091CBT

The GS4B033091CBT stands out for its precision, compactness, and rugged ceramic construction, offering engineers a reliable solution for high-accuracy applications.
