GS8A011780FFT

GS8A011780FFT Description

The GS8A011780FFT from TT Electronics/IRC is a high-performance 8-resistor isolated network in a 16-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. Encased in a ceramic SOIC-C series housing, it offers excellent thermal stability with a ±100ppm/°C temperature coefficient and ±1% absolute tolerance. Each resistor features a 178Ω value, rated for 0.1W (1/10W) per element (0.8W total), and operates within a 70°C to 125°C derated power range, peaking at 125°C. Its 100V maximum voltage rating and gull-wing termination ensure reliable surface-mount integration. The 9.91mm × 5.99mm × 1.45mm compact form factor (±0.1mm length/height tolerance) suits space-constrained designs.

GS8A011780FFT Features

• Isolated Circuit Design: Independent resistors (no common terminal) for flexible circuit configurations.
• High Precision: 1% tolerance on both absolute and ratio values, critical for differential signal processing.
• Robust Construction: Ceramic substrate with thin-film technology ensures low noise and long-term stability.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated above 70°C).
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its ceramic packaging offers superior thermal handling vs. plastic counterparts.
• EU RoHS Status: Non-compliant, making it suitable for legacy or specialized industrial systems.

GS8A011780FFT Applications

Ideal for precision analog circuits, medical instrumentation, and test/measurement equipment where resistor matching and isolation are critical. Commonly used in:

• Voltage dividers and current sensing networks requiring tight tolerance ratios.
• Isolated signal conditioning in industrial PLCs and motor drives.
• A/D converter reference circuits benefiting from low TCR drift.
• Aerospace and defense systems (where ceramic packaging excels in harsh environments).

Conclusion of GS8A011780FFT

The GS8A011780FFT stands out for its ceramic-based isolation, tight tolerances, and thin-film reliability, making it a superior choice over polymer-based networks in high-temperature or precision-demanding scenarios. While not automotive-grade, its 125°C rating and low TCR cater to industrial and instrumentation needs. Engineers should evaluate RoHS compliance requirements but can leverage its stable performance in critical analog designs.
