GS8A018250BT

GS8A018250BT Description

The GS8A018250BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features an 825Ω resistance value per resistor with an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 16-pin SOIC package with gull-wing termination, it offers 0.8W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating. The ceramic substrate enhances thermal stability, while the isolated (ISOL) circuit design minimizes crosstalk.

GS8A018250BT Features

• Precision Thin Film Technology: Delivers ±0.1% tolerance and ±100ppm/°C TCR for critical analog circuits.
• Robust Construction: Ceramic case ensures high thermal conductivity and mechanical durability.
• Space-Efficient Design: 9.91mm × 5.99mm × 1.45mm SOIC package with 1.27mm pitch for high-density PCB layouts.
• Isolated Resistors: Independent resistors (ISOL design) prevent signal interference in multi-channel systems.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power handling.
• Surface-Mount Gull Wing Terminals: Facilitates automated assembly and secure PCB mounting.

GS8A018250BT Applications

This resistor network is ideal for:

• Precision Voltage Dividers in test & measurement equipment.
• Signal Isolation in industrial PLCs and process control systems.
• Analog Front-Ends for medical devices (e.g., patient monitoring).
• Feedback Networks in high-accuracy DC/DC converters.
• Sensor Conditioning Circuits where minimal drift is critical (e.g., automotive sensors, though non-automotive qualified).

Conclusion of GS8A018250BT

The GS8A018250BT excels in applications requiring high precision, thermal stability, and electrical isolation. Its ceramic substrate, thin-film technology, and isolated design make it superior to standard epoxy-based networks in harsh environments. While not PPAP or automotive-qualified, it is a cost-effective solution for industrial, medical, and instrumentation designs where reliability and accuracy are paramount. The tube packaging ensures protection during handling and assembly.
