GS4A021503JT

GS4A021503JT Description

The GS4A021503JT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding environments. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 150 kΩ resistance and a ±5% tolerance. The device operates within a wide temperature range of 70°C to 125°C, with a ±50 ppm/°C temperature coefficient, ensuring stable performance under thermal stress. Encased in a rectangular ceramic SOIC package, it offers excellent durability and 0.4W total power dissipation (0.1W per resistor). Its 100V maximum voltage rating and gull-wing termination make it suitable for surface-mount PCB designs, while its compact dimensions (4.9mm x 5.99mm x 1.45mm) enable high-density layouts.

GS4A021503JT Features

• Isolated Resistor Network: Four independent resistors in an 8-pin SOIC package, ideal for signal isolation.
• High Stability: ±50 ppm/°C TCR and ceramic substrate ensure minimal drift under thermal or electrical stress.
• Robust Construction: Thin-film technology provides superior accuracy and long-term reliability.
• Space-Efficient: Ultra-thin 1.45mm profile and 1.27mm terminal pitch for compact designs.
• Wide Operating Range: -55°C to +125°C (derated above 70°C) suits industrial and automotive-grade applications.
• Non-Compliant with EU RoHS, which may be preferable for certain legacy or high-reliability systems.

GS4A021503JT Applications

• Signal Conditioning: Precision voltage dividers or pull-up/down networks in analog circuits.
