GS4B032872FCT Description

The GS4B032872FCT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for surface-mount applications. Encased in a ceramic SOIC-8 package, it offers a 28.7KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. The network is rated for 0.4W total power dissipation (0.05W per resistor) and supports a maximum voltage of 100V, making it suitable for demanding circuit designs. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB mounting, while the ceramic substrate enhances thermal and mechanical durability.

GS4B032872FCT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Ceramic SOIC Package: Combines high thermal conductivity with compact dimensions (4.9mm × 5.99mm × 1.45mm).
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power up to 125°C.
• BUS Circuit Designator: Optimized for bus termination, voltage division, or pull-up/down applications.
• Robust Construction: Gull-wing leads and ±0.1mm height/length tolerances ensure consistent SMD assembly.
• Non-Automotive Grade: Ideal for industrial, telecom, and instrumentation where PPAP compliance is not required.
