GS4B021402CCT

GS4B021402CCT Description

The GS4B021402CCT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for surface-mount applications. Encased in a ceramic SOIC-8 package, it delivers 14KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, it features gull-wing terminations with a 1.27mm pitch for reliable PCB mounting. The ceramic substrate enhances thermal performance, while the compact dimensions (4.9mm x 5.99mm x 1.45mm) suit space-constrained designs.

GS4B021402CCT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±0.25%) for critical analog circuits.
• Robust Ceramic Construction: Superior heat dissipation and mechanical durability vs. polymer-based arrays.
• BUS Circuit Designator: Optimized for bus termination, voltage division, and pull-up/down networks.
• Extended Temperature Range: Stable performance from 70°C to 125°C with derated power handling.
• Automotive-Grade Alternatives: While not PPAP-certified, its 125°C rating makes it suitable for industrial and telecom applications.
• EU RoHS Non-Compliance: Note: Contains restricted materials; verify compatibility with environmental regulations.

GS4B021402CCT Applications

• Signal Conditioning: Ideal for ADC/DAC reference networks and sensor interfaces requiring low drift.
• Bus Termination: Used in high-speed digital systems (e.g., DDR memory, CAN buses) to reduce reflections.
• Medical Electronics: Precision dividers in patient monitoring equipment due to low TCR and high stability.
• Industrial Controls: PLC I/O modules benefit from its compact footprint and reliability under thermal stress.
• Test & Measurement: Calibration circuits where sub-1% tolerance is critical.

Conclusion of GS4B021402CCT

The GS4B021402CCT excels in precision analog and mixed-signal designs, combining thin film accuracy, ceramic ruggedness, and space-efficient packaging. Its 14KΩ BUS configuration and 0.25% tolerance make it a standout for termination, biasing, and signal integrity tasks. While not RoHS-compliant, it remains a robust choice for industrial, medical, and telecom systems demanding long-term stability. Engineers should evaluate alternative models (e.g., RoHS-compliant variants) for eco-sensitive applications.
