GS4B024220JDT Description

The GS4B024220JDT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. Encased in a ceramic substrate, it delivers excellent thermal stability with a ±50ppm/°C temperature coefficient and a 5% absolute tolerance (±0.5% ratio tolerance). The network operates across a wide temperature range (-70°C to +125°C) and supports a maximum voltage rating of 100V, making it suitable for demanding environments. Its 0.05W (1/20) power rating per resistor and 0.4W total power dissipation ensure reliable performance in compact designs. The gull-wing termination and surface-mount (SOIC) form factor facilitate easy PCB integration.

GS4B024220JDT Features

• Bussed Network Design: 7 resistors connected in a single bus configuration (422Ω each), simplifying circuit layout.
• High Stability: Thin-film technology with ±50ppm/°C TCR ensures minimal resistance drift.
• Robust Construction: Ceramic case enhances thermal and mechanical durability.
• Precision Tolerance: ±5% absolute tolerance (±0.5% ratio tolerance) for consistent performance.
• Wide Operating Range: Functions reliably from -70°C to +125°C (derated power).
• Compact Footprint: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length).
• Surface-Mount Ready: 1.27mm terminal pitch and gull-wing leads for automated assembly.

GS4B024220JDT Applications

Ideal for precision analog circuits, voltage dividers, and sensor signal conditioning in:

• Industrial Control Systems: Stable resistance for PLCs and instrumentation.
• Automotive Electronics: Despite non-automotive PPAP status, suitable for non-safety-critical modules.
• Medical Devices: Reliable performance in diagnostic equipment.
• Telecom Infrastructure: Signal processing in base stations and routers.
• Power Management: Current-limiting and bias networks in DC/DC converters.

Conclusion of GS4B024220JDT

The GS4B024220JDT excels in applications demanding tight tolerance, thermal stability, and compact integration. Its ceramic construction and thin-film technology offer superior reliability over standard thick-film networks, while the bussed design reduces component count. Though non-RoHS compliant, it remains a robust choice for industrial and telecom systems where precision and durability are critical. Engineers will appreciate its balance of performance, size, and cost in space-constrained designs.
