GS4B033321JBT Description

The GS4B033321JBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor network features a 3.32KΩ resistance value per resistor with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in an 8-pin SOIC ceramic package, it offers a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for compact, high-density circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its rectangular ceramic case enhances thermal and mechanical durability.

GS4B033321JBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Robust Ceramic Package: Ensures superior heat dissipation and mechanical strength compared to plastic alternatives.
• BUS Circuit Designator: Optimized for bus line termination, voltage division, and pull-up/down applications.
• Tight Tolerances: ±0.1mm length/height tolerances and ±0.2mm depth tolerance for consistent placement.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• Non-Automotive Grade: Ideal for industrial, telecom, and instrumentation use where PPAP compliance isn’t required.

GS4B033321JBT Applications

• Signal Conditioning: Precision voltage dividers in ADC/DAC circuits.
• Bus Line Termination: Impedance matching in high-speed data lines (e.g., SPI, I²C).
• Power Management: Load sharing in low-power DC/DC converters.
• Industrial Controls: Feedback networks in sensor interfaces or PLCs.
• Test & Measurement Equipment: Stable reference resistors for calibration systems.

Conclusion of GS4B033321JBT

The GS4B033321JBT excels in applications requiring compact size, high reliability, and tight electrical tolerances. Its ceramic SOIC package and thin-film construction provide a competitive edge in thermal performance and longevity over polymer-based networks. While not RoHS-compliant, it remains a top choice for non-automotive industrial systems where precision and durability are critical. Engineers will appreciate its balance of performance, ease of assembly, and cost-effectiveness in medium-complexity designs.
