GS4B021542DBT Description

The GS4B021542DBT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for BUS circuit applications. Encased in a ceramic SOIC-8 package, it offers a 15.4KΩ resistance per resistor with an exceptional ±0.5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic substrate enhances thermal performance and durability.

GS4B021542DBT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±0.5%) for critical analog/digital circuits.
• Robust Ceramic Package: Superior heat dissipation and mechanical strength compared to polymer-based arrays.
• Wide Temperature Range: Stable performance from -70°C to +125°C, even at derated power.
• High-Density Integration: 7 resistors in a compact 4.9mm × 5.99mm footprint, saving board space.
• Automation-Friendly: Gull-wing leads and 1.27mm pitch align with standard SMD assembly processes.
• Non-Automotive PPAP: Ideal for industrial/consumer applications where PPAP compliance isn’t required.

GS4B021542DBT Applications

This resistor network excels in:

• Voltage Division/Current Limiting: Precision dividers in sensor interfaces or ADC reference circuits.
• Bus Termination/Impedance Matching: Critical for high-speed data lines (e.g., CAN, I2C) to reduce reflections.
• Medical/Test Equipment: Where low TCR (±50ppm/°C) ensures long-term calibration stability.
• Power Supply Feedback Networks: Thin film’s low noise minimizes ripple in regulation loops.
• Industrial Controls: Ceramic construction withstands harsh environments (vibration, thermal cycling).

Conclusion of GS4B021542DBT

The GS4B021542DBT stands out for its precision, ruggedness, and space efficiency, making it a top choice for engineers prioritizing reliability in compact designs. While not RoHS-compliant, its ceramic SOIC package and thin film technology offer superior performance over epoxy-based alternatives in high-temperature or precision-critical applications. Ideal for industrial, medical, and communication systems, this network balances cost and performance for non-automotive use cases.
