GS8A016490BT

GS8A016490BT Description

The GS8A016490BT from TT Electronics/IRC is a high-precision 8-resistor thin film network in a 16-pin SOIC package, designed for isolation (ISOL) circuit applications. With a 649Ω resistance value and tight 0.1% tolerance, it ensures exceptional accuracy in signal conditioning and voltage division. The ceramic-based construction offers superior thermal stability, operating across a -70°C to +125°C temperature range with a low ±100ppm/°C TCR. Rated for 0.8W total power dissipation (0.1W per resistor) and 100V maximum voltage, it suits demanding environments. The gull-wing termination and surface-mount design facilitate automated PCB assembly, while the tube packaging ensures handling protection.

GS8A016490BT Features

• Precision Performance: 0.1% tolerance and ±100ppm/°C TCR for stable operation in temperature-variable environments.
• Robust Construction: Ceramic case and thin film technology enhance durability and long-term reliability.
• High Power Handling: 0.8W total power rating (0.1W per resistor) with derating up to 125°C.
• Compact & Standardized: SOIC-16 footprint (9.91mm x 5.99mm x 1.45mm) with ±0.1mm dimensional tolerances.
• Isolation-Centric Design: ISOL circuit configuration minimizes crosstalk in multi-channel systems.
• Non-Automotive Grade: Ideal for industrial and telecom applications where PPAP compliance is not required.

GS8A016490BT Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor signal conditioning.
• Test & Measurement Equipment: High-accuracy instrumentation requiring stable resistance values.
• Industrial Control Systems: Isolated signal paths in PLCs and motor drives.
• Telecom Infrastructure: Impedance matching and filtering in base stations.
• Medical Electronics: Low-drift circuits in diagnostic devices (note: EU RoHS non-compliant).

Conclusion of GS8A016490BT

The GS8A016490BT excels in applications demanding precision, thermal resilience, and compact integration. Its ceramic SOIC package and isolated thin film resistors provide a competitive edge over polymer-based networks in high-temperature or high-reliability scenarios. While not suited for automotive use, it is a cost-effective solution for industrial, telecom, and test equipment where tight tolerances and low TCR are critical. Engineers should verify RoHS compliance for eco-sensitive designs.
