GS4A018662JBT Description

The GS4A018662JBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. Housed in an 8-pin narrow SOIC (SOIC-C) package, this 4-resistor isolated network features 86.6KΩ resistance per element with an absolute tolerance of ±5% and an exceptional ratio tolerance of ±0.1%. Its thin-film technology ensures low noise and high reliability, while the ceramic case provides excellent thermal conductivity and mechanical durability. Rated for 0.1W (1/10W) power dissipation per resistor (0.4W total), it operates across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments.

GS4A018662JBT Features

• Isolated Circuit Design (ISOL): Independent resistors minimize crosstalk, ideal for signal isolation.
• High Precision: ±100ppm/°C temperature coefficient ensures stability under thermal stress.
• Robust Construction: Ceramic substrate and gull-wing termination enhance solderability and mechanical strength.
• Surface-Mount (SOIC) Package: Compact 4.9mm x 5.99mm footprint with a 1.63mm profile suits space-constrained PCBs.
• Wide Voltage Rating: Supports up to 100V, accommodating industrial and automotive-grade applications (though non-automotive PPAP).
• Strict Tolerances: ±0.1% ratio tolerance critical for differential amplifiers and precision dividers.
