GS8A0154R9DDT

GS8A0154R9DDT Description

The GS8A0154R9DDT from TT Electronics/IRC is a high-precision 8-resistor network in a 16-pin narrow SOIC package, designed for isolated circuit applications (ISOL). Built with ceramic substrate and thin-film technology, it delivers stable performance with a 54.9Ω resistance per element, ±0.5% absolute tolerance, and ±100ppm/°C temperature coefficient. The SOIC-C series construction ensures robustness in demanding environments, with a 0.1W power rating per resistor (0.8W total) and 100V maximum voltage rating. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the rectangular ceramic case offers superior thermal and mechanical stability.

GS8A0154R9DDT Features

• Precision Network: 8 isolated resistors with ±0.5% ratio tolerance for matched performance.
• High-Temperature Operation: Rated for 125°C max operating temperature (derated power: 70–125°C).
• Stable Thin-Film Technology: Low TCR (±100ppm/°C) ensures minimal drift under thermal stress.
• Compact & Durable: 9.91mm × 5.99mm × 1.45mm dimensions (±0.1mm tolerance) in a ceramic SOIC package for high reliability.
• Automotive-Grade Alternatives: While not PPAP/automotive-certified, its 100V rating and wide temp range suit industrial applications.
• Non-RoHS Compliant: Ideal for legacy or specialized systems requiring non-compliant materials.

GS8A0154R9DDT Applications

• Signal Conditioning: Precision voltage dividers or feedback networks in test equipment and DAQ systems.
• Isolation Circuits: Buffering or impedance matching in medical isolation barriers or industrial control systems.
• Power Management: Current sensing or load balancing in power supplies and DC-DC converters.
• Legacy Electronics: Repair or replacement in military/aerospace systems where RoHS compliance is not mandated.
