GS4A021270JFT

GS4A021270JFT Description

The GS4A021270JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 4-resistor network is housed in an 8-pin narrow SOIC (SOIC-C) package, featuring isolated elements for enhanced signal integrity. With a 127Ω resistance value and a ±5% absolute tolerance, it ensures consistent performance in demanding circuits. The thin-film technology and ±50ppm/°C temperature coefficient provide excellent stability across a wide operating temperature range of -70°C to +125°C. Its 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for low-power, high-voltage environments.

GS4A021270JFT Features

• Ceramic Construction: Ensures durability and thermal stability in harsh conditions.
• Isolated Resistors (4x): Prevents crosstalk, ideal for precision analog/digital circuits.
• Thin-Film Technology: Delivers low noise and high accuracy (±5% tolerance, ±1% ratio tolerance).
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power up to 125°C.
• SOIC Package (4.9mm x 5.99mm x 1.45mm): Compact, surface-mountable design with gull-wing leads for easy PCB integration.
• Low TCR (±50ppm/°C): Minimizes resistance drift under thermal stress.
• 100V Maximum Rating: Suitable for industrial and automotive-grade voltage levels (though not PPAP/AEC-Q200 certified).

GS4A021270JFT Applications

• Isolation Circuits: Used in op-amp feedback networks, DAC/ADC interfaces, and signal conditioning where isolation is critical.
• Medical Electronics: Precision dividers and sensor interfaces due to low TCR and stable thin-film performance.
• Industrial Controls: PLC modules, motor drivers, and power management systems requiring high-voltage tolerance.
• Test & Measurement Equipment: Calibration circuits and reference networks benefiting from ±1% ratio tolerance.
• Telecom Infrastructure: Line termination and impedance matching in high-frequency PCBs.
