GS4B0161R9GT

GS4B0161R9GT Description

The GS4B0161R9GT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable resistance values under varying conditions. Built with ceramic substrate and thin-film technology, it offers a 61.9Ω resistance per element with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring reliable performance across a -70°C to +125°C operating range. The SOIC-C series construction provides robust mechanical stability, while the gull-wing termination facilitates easy surface mounting. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, this network is engineered for efficiency in compact designs.

GS4B0161R9GT Features

• Bussed Network Design: Simplifies circuit layout by connecting resistors in a common bus configuration, reducing component count.
• High-Temperature Stability: Operates reliably up to 125°C, with derated power handling up to 70°C.
• Precision Thin Film: Delivers low noise and excellent resistance stability compared to thick-film alternatives.
• Compact SOIC Package: 4.9mm × 5.99mm × 1.45mm dimensions with ±0.1mm length/height tolerances, ideal for space-constrained PCBs.
• Automated Assembly Friendly: 1.27mm terminal pitch and gull-wing leads optimize pick-and-place compatibility.
• Non-Automotive Grade: Suitable for industrial, telecom, and consumer electronics where PPAP compliance is not required.

GS4B0161R9GT Applications

This resistor network excels in:

• Voltage Divider Circuits: Precision attenuation in sensor interfaces or ADC front-ends.
• Bus Termination: Impedance matching in low-power digital communication lines (e.g., I²C, SPI).
• Signal Conditioning: Stable biasing for op-amps or comparators in measurement equipment.
• Power Management: Current limiting in distributed power systems with derated thermal requirements.
• Industrial Controls: Harsh-environment applications benefiting from ceramic substrate durability.

Conclusion of GS4B0161R9GT

The GS4B0161R9GT stands out for its combination of precision, compactness, and thermal resilience, making it a superior choice over generic thick-film networks in mission-critical analog circuits. Its bussed architecture reduces PCB complexity, while the thin-film ceramic construction ensures long-term reliability. Though not RoHS-compliant, it remains a cost-effective solution for non-automotive sectors demanding stable performance in moderate-temperature environments. Engineers will appreciate its balance of tight tolerances, low TCR, and ease of integration in high-density designs.
