GS4B021782JDT

GS4B021782JDT Description

The GS4B021782JDT 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 SOIC-C series housing, it offers a 17.8KΩ resistance per element with an absolute tolerance of ±5% and a tight ratio tolerance of ±0.5%, ensuring consistent performance in differential circuits. The device operates over a wide temperature range of 70°C to 125°C with a derated power profile, maintaining reliability under thermal stress. Its ±50ppm/°C temperature coefficient minimizes drift, while the 100V maximum voltage rating and 0.4W total power dissipation (0.05W per resistor) suit medium-power designs. The gull-wing termination and 1.27mm pitch enable robust surface-mount assembly, with dimensions of 4.9mm (L) × 5.99mm (D) × 1.45mm (H).

GS4B021782JDT Features

• Bussed Network Architecture: Simplifies PCB layout by connecting resistors in a common bus configuration.
• High Stability: Thin-film technology and ceramic case ensure low noise and long-term reliability.
• Precision Tolerance: ±5% absolute and ±0.5% ratio tolerance for matched performance in differential pairs.
• Robust Construction: SOIC package with 1.63mm seated height withstands mechanical stress.
• Wide Operating Range: -55°C to +125°C (full power up to 70°C) for harsh environments.
• Low TCR: ±50ppm/°C minimizes resistance shift with temperature.

GS4B021782JDT Applications

• Analog Signal Conditioning: Ideal for op-amp feedback networks and voltage dividers in instrumentation.
• Industrial Controls: Used in PLCs and sensor interfaces where stable resistance ratios are critical.
• Automotive Electronics: Suitable for non-safety-critical modules (e.g., infotainment) despite non-automotive PPAP status.
• Power Management: Balances current in multi-channel DC/DC converters.
• Medical Devices: Precision networks for diagnostic equipment due to low drift.

Conclusion of GS4B021782JDT

The GS4B021782JDT excels in applications demanding tight tolerance ratios, thermal stability, and compact form factor. Its ceramic SOIC package and thin-film resistors provide superior performance over polymer-based networks, while the bussed design reduces component count. Though non-compliant with EU RoHS, it remains a cost-effective choice for industrial and commercial systems where precision and durability are paramount. Engineers will value its balance of power handling, voltage tolerance, and ease of integration in space-constrained designs.
