GS8B034321CCT

GS8B034321CCT Description

The GS8B034321CCT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerance and stability. Housed in a 16-pin narrow SOIC package, this bussed (BUS) network integrates 15 thin-film resistors, each with a 4.32KΩ resistance and an absolute tolerance of ±0.25%. The device operates over a wide temperature range (-70°C to +125°C) with a low temperature coefficient of ±25ppm/°C, ensuring minimal resistance drift. Its 0.05W (1/20) power rating per resistor and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The SOIC-C series construction features a rectangular ceramic case with gull-wing termination, optimized for surface-mount assembly.

GS8B034321CCT Features

• High Precision: ±0.25% tolerance and ±25ppm/°C TCR for stable performance in varying environments.
• Robust Construction: Ceramic substrate enhances thermal and mechanical durability.
• Space-Efficient: Compact 9.91mm × 5.99mm × 1.45mm footprint with 1.27mm terminal pitch.
• Bussed Design: Simplifies PCB layout by connecting multiple resistors to a common node (BUS).
• Wide Operating Range: Derated power up to 125°C, ideal for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• Low Power Dissipation: 0.8W total power rating (0.05W per resistor) balances performance and energy efficiency.

GS8B034321CCT Applications

• Precision Voltage Dividers: Critical in ADC/DAC reference circuits due to tight ratio tolerance (±0.25%).
• Signal Conditioning: Stable resistance values ensure accuracy in sensor interfaces and instrumentation.
• Industrial Controls: Reliable operation in harsh environments (e.g., PLCs, motor drives).
• Medical Electronics: Low drift and high tolerance meet stringent medical device requirements.
• Communications Equipment: Used in RF matching networks and filter circuits.

Conclusion of GS8B034321CCT

The GS8B034321CCT excels in applications demanding high precision, thermal stability, and compactness. Its ceramic thin-film technology and bussed architecture offer superior performance over polymer-based networks, particularly in high-temperature or precision-critical systems. While not automotive-grade, its 125°C rating and tight tolerances make it a versatile choice for industrial, medical, and telecom designs. Engineers will appreciate its balance of size, accuracy, and robustness, though RoHS non-compliance may limit use in eco-regulated markets.
