GS4B012802JT

GS4B012802JT Description

The GS4B012802JT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. Packaged in an 8-pin narrow SOIC (SOIC-C Series), this 7-resistor bussed network offers a 28KΩ resistance per element with a ±5% tolerance and a ±100ppm/°C temperature coefficient. Its thin-film technology ensures stable performance across a wide temperature range (70°C to 125°C derated, 125°C max operating). The device features a 0.4W total power rating (0.05W per resistor) and supports 100V maximum voltage, making it suitable for low-power, high-reliability designs. The gull-wing termination and surface-mount (SMD) compatibility facilitate easy PCB integration.

GS4B012802JT Features

• Ceramic substrate for enhanced thermal stability and durability.
• Bussed circuit design (BUS) simplifies routing in multi-resistor applications.
• Compact SOIC package (4.9mm × 5.99mm × 1.45mm) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Low TCR (±100ppm/°C) ensures minimal resistance drift under temperature fluctuations.
• RoHS non-compliant (note for restricted applications).
• Tube packaging for automated assembly processes.

GS4B012802JT Applications

Ideal for signal conditioning, voltage division, and bus termination in:

• Industrial control systems requiring stable resistance under thermal stress.
• Telecommunications equipment where space-efficient networks are critical.
• Test and measurement devices demanding precision and repeatability.
• Automotive subsystems (non-AECQ qualified; verify suitability for non-safety-critical roles).

Conclusion of GS4B012802JT

The GS4B012802JT stands out for its ceramic construction, tight tolerances, and bussed architecture, offering reliability in compact designs. While not PPAP or automotive-grade, its thin-film technology and robust thermal performance make it a cost-effective choice for industrial and telecom applications. Engineers should evaluate RoHS compliance for regulated markets.
