GS4B028200FT

GS4B028200FT Description

The GS4B028200FT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed with thin-film technology on a ceramic substrate, it offers a 820Ω resistance per element with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient. The device operates over a wide temperature range (-70°C to +125°C) and delivers a 0.4W total power rating (0.05W per resistor). Its 100V maximum voltage rating and gull-wing termination make it suitable for precision applications requiring stable performance under varying conditions. The SOIC-C series construction ensures durability, while the non-compliant EU RoHS status may be noted for specific regulatory considerations.

GS4B028200FT Features

• Ceramic Case & Thin Film Tech: Ensures high reliability, low noise, and stable performance in harsh environments.
• Bussed Network (7R/8-Pin): Simplifies PCB layout by reducing discrete component count.
• Precision Specifications: ±1% tolerance, ±50ppm/°C TCR, and 0.05W/resistor power handling.
• Robust Packaging: SOIC-8 with 1.27mm pitch and surface-mount design for automated assembly.
• Wide Temp Range: Operates from -70°C to +125°C (derated above 70°C), ideal for industrial and automotive-grade designs (though not PPAP/automotive-certified).
• Non-RoHS: May be preferred for legacy or exempt applications.

GS4B028200FT Applications

This resistor network excels in:

• Signal Conditioning: Voltage dividers, pull-up/down networks in IoT devices, sensors, and communication modules.
• Industrial Controls: PLC systems, motor drives, and power management circuits requiring stable resistance under thermal stress.
• Test & Measurement Equipment: Precision reference circuits due to low TCR and tight tolerance.
• Legacy Electronics: Non-RoHS compliance suits military/aerospace or niche industrial systems with exemption requirements.

Conclusion of GS4B028200FT

The GS4B028200FT stands out for its ceramic-based durability, precision thin-film resistors, and compact SOIC-8 footprint. While not automotive-grade, its wide temperature range and bussed design make it a cost-effective solution for high-density PCBs demanding reliability. Ideal for engineers prioritizing performance-per-space efficiency in industrial, instrumentation, or legacy systems. For non-RoHS applications, it offers a viable alternative to compliant models without sacrificing technical rigor.
