GS4B033010JT

GS4B033010JT Description

The GS4B033010JT 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 offers superior thermal stability with a ±25ppm/°C temperature coefficient and a 5% tolerance on its 301Ω resistance value. Rated for 0.4W total power dissipation (0.05W per resistor), it operates across a wide temperature range of -70°C to +125°C, making it suitable for harsh environments. The gull-wing termination ensures reliable surface-mount assembly, while its 100V maximum voltage rating and non-compliant EU RoHS status cater to industrial and legacy designs.

GS4B033010JT Features

• Ceramic Construction: Enhances thermal conductivity and durability.
• Bussed Network (BUS): Simplifies circuit design with shared connections.
• Thin-Film Technology: Delivers low noise and high precision (±5% tolerance).
• High-Temp Operation: Reliable performance up to 125°C with derating up to 70°C.
• Compact SOIC Package: 4.9mm × 5.99mm × 1.45mm dimensions with tight tolerances (±0.1mm height/length).
• Automotive-Grade Alternatives: While not PPAP/automotive-certified, its robustness suits industrial analogs.

GS4B033010JT Applications

Ideal for:

• Voltage Divider Networks: Precision dividers in test equipment.
• Signal Conditioning: Analog/digital interfaces where stability is critical.
• Legacy Industrial Systems: Non-RoHS compliant designs requiring high-voltage tolerance.
• Power Management: Auxiliary circuits in power supplies (derated power handling).
• Harsh Environments: Ceramic casing resists thermal stress in aerospace or defense subsystems.

Conclusion of GS4B033010JT

The GS4B033010JT excels in precision, thermal resilience, and space efficiency, distinguishing itself from polymer-based networks. Its ceramic SOIC package and bussed architecture reduce PCB complexity, while the thin-film technology ensures long-term reliability. Though not automotive-qualified, it’s a cost-effective solution for industrial, instrumentation, and high-temperature applications demanding stable performance under stress. Engineers should verify compatibility for RoHS-restricted designs.
