GS4B028250CBT Description

The GS4B028250CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding circuit applications. This 7-resistor BUS-configuration array offers a 825Ω resistance per element with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Housed in a ceramic SOIC-8 package, it features gull-wing SMD terminations for reliable surface mounting. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, this non-automotive, non-PPAP compliant component is ideal for precision analog and digital systems.

GS4B028250CBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive circuits.
• Compact & Robust: 4.9mm × 5.99mm × 1.45mm ceramic SOIC package with ±0.1mm length/height tolerances ensures consistent PCB integration.
• High Power Density: 0.4W total dissipation (1/20W per resistor) in a small footprint.
• Wide Temperature Range: Operates from -70°C to +125°C with derated performance up to 125°C.
• Low TCR: ±50ppm/°C minimizes resistance drift in variable environments.
• BUS Configuration: Simplifies circuit design for voltage division, pull-up/down networks, and impedance matching.

GS4B028250CBT Applications

• Precision Instrumentation: Ideal for DAC/ADC reference networks, medical devices, and test equipment.
• Industrial Controls: Suitable for PLCs, sensor interfaces, and power management circuits.
• Telecom & Networking: Used in line termination, signal conditioning, and RF modules.
• Consumer Electronics: High-end audio/video systems requiring low-tolerance resistor arrays.

Conclusion of GS4B028250CBT

The GS4B028250CBT excels in applications demanding tight tolerance, low TCR, and compact packaging. Its ceramic construction and thin-film technology provide superior reliability compared to thick-film alternatives, while the SOIC-8 gull-wing design ensures compatibility with automated assembly. Though not RoHS-compliant, it remains a top choice for industrial and precision electronics where performance outweighs regulatory constraints.
