GS4A012212FT

GS4A012212FT Description

The GS4A012212FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a 22.1 kΩ resistance and a tight ±1% tolerance. The device operates over a wide temperature range of 70°C to 125°C with a derated power rating, ensuring reliability in demanding environments. Its ±100 ppm/°C temperature coefficient minimizes resistance drift, while the 100V maximum voltage rating and 0.1W power rating per resistor make it suitable for low-power circuits. The SOIC-C series construction offers robust ceramic case durability, ideal for surface-mount applications requiring stability and precision.

GS4A012212FT Features

• Isolated Resistors: Four independent resistors (22.1 kΩ each) with 1% absolute tolerance for precise signal conditioning.
• High-Temperature Stability: Operates up to 125°C with a derated power profile (0.1W per resistor).
• Low TCR: ±100 ppm/°C ensures minimal resistance variation across temperature fluctuations.
• Robust Packaging: Ceramic SOIC case with gull-wing termination for reliable surface-mount (SMD) assembly.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).
• High Voltage Rating: Supports up to 100V, suitable for industrial and automotive-grade designs (though non-automotive per PPAP).

GS4A012212FT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring stable resistance values.
• Signal Isolation: Isolated resistor banks in data acquisition systems or medical instrumentation.
• Industrial Controls: Robust performance in PLC modules, power supplies, and test equipment.
• Telecom & Networking: Signal conditioning in high-frequency PCBs due to low parasitic effects of thin-film technology.

Conclusion of GS4A012212FT

The GS4A012212FT combines high precision, thermal stability, and compact form factor, making it a superior choice for engineers prioritizing reliability in harsh environments. Its ceramic SOIC package and isolated design offer distinct advantages over polymer-based networks, particularly in applications demanding low TCR and high voltage tolerance. While not PPAP-certified for automotive use, it remains ideal for industrial, telecom, and precision electronics where consistent performance is critical.
