GS7B017321CAT

GS7B017321CAT Description

The GS7B017321CAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding surface-mount applications. This 14-pin narrow SOIC package features 13 bussed (BUS) thin-film resistors, each with a 7.32KΩ resistance and an exceptional ±0.25% absolute tolerance (±0.05% ratio tolerance). Its SOIC-C series construction ensures reliability in compact PCB layouts, with a rectangular ceramic case offering superior thermal stability. Rated for 0.7W total power dissipation (0.05W per resistor), it operates across a wide temperature range of -70°C to +125°C, making it suitable for harsh environments. The ±100ppm/°C temperature coefficient and 100V maximum voltage rating further enhance its performance in precision circuits.

GS7B017321CAT Features

• High Precision: ±0.25% tolerance and ±0.05% ratio tolerance for critical analog/digital applications.
• Robust Construction: Ceramic substrate with gull-wing termination ensures durability and solderability.
• Thermal Performance: Thin-film technology and 125°C maximum operating temperature enable stable performance under load.
• Compact Design: 8.66mm × 5.99mm × 1.45mm dimensions with tight tolerances (±0.1mm height/length, ±0.2mm depth) for space-constrained designs.
• Automation-Friendly: Tube packaging and 1.27mm terminal pitch simplify pick-and-place assembly.
• Non-Automotive/Non-PPAP: Ideal for industrial, medical, and instrumentation use where automotive compliance isn’t required.

GS7B017321CAT Applications

This resistor network excels in:

• Precision Voltage Dividers: Due to its low ratio tolerance, it’s perfect for ADC/DAC reference circuits.
• Signal Conditioning: Stable performance in sensor interfaces and feedback loops.
• Industrial Controls: Withstands high temperatures in PLCs and motor drives.
• Medical Devices: Ceramic construction resists moisture and contaminants.
• Test & Measurement Equipment: Low TCR (±100ppm/°C) minimizes drift in calibration systems.

Conclusion of GS7B017321CAT

The GS7B017321CAT combines precision, compactness, and thermal resilience, outperforming generic resistor arrays in critical applications. Its ceramic SOIC package and bussed topology simplify design while meeting stringent tolerance requirements. While not RoHS-compliant or automotive-grade, it’s a cost-effective solution for industrial and medical electronics where reliability and accuracy are paramount. Engineers will appreciate its balance of performance and manufacturability in high-density PCBs.
