GS7B015490CT

GS7B015490CT Description

The GS7B015490CT from TT Electronics/IRC is a high-precision Ceramic Resistor Network designed for demanding electronic applications. Housed in a 14-pin Narrow SOIC package, this bussed (BUS) network integrates 13 thin-film resistors with a 549Ω resistance value and an exceptional ±0.25% absolute tolerance. Its ±100ppm/°C temperature coefficient ensures stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The SOIC-C series construction features a rectangular ceramic case with gull-wing terminations, optimized for surface-mount (SMD) assembly. With a 0.7W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances compactness with reliability.

GS7B015490CT Features

• Precision & Stability: 0.25% tolerance and ±100ppm/°C TCR for consistent performance in precision circuits.
• Robust Construction: Ceramic substrate enhances thermal dissipation and mechanical durability.
• Space-Efficient: 8.66mm × 5.99mm × 1.45mm dimensions with 1.27mm terminal pitch suit high-density PCB designs.
• High-Temperature Operation: Rated for 125°C maximum temperature, ideal for industrial or automotive-adjacent applications (though not PPAP/automotive-certified).
• Bussed Configuration: Simplifies circuit design by connecting multiple resistors to a common node.
• Non-RoHS (EU): Note for compliance-sensitive designs.

GS7B015490CT Applications

• Analog Signal Conditioning: Precision voltage dividers or sensor interfaces in test equipment.
• Medical Electronics: Stable resistor networks for diagnostic devices where accuracy is critical.
• Industrial Controls: Motor drives or power supplies requiring high-temperature resilience.
• Communications Infrastructure: RF modules or filtering circuits benefiting from low TCR drift.
• Legacy Systems: Non-RoHS compliance may suit specific industrial or military refurbishments.

Conclusion of GS7B015490CT

The GS7B015490CT excels in applications demanding tight tolerance, thermal stability, and compact integration. Its ceramic thin-film technology and bussed architecture reduce component count while maintaining precision, offering a competitive edge over polymer-based or lower-tolerance networks. While not automotive-grade, its 125°C rating and high-voltage capability make it a versatile choice for industrial, medical, and communication systems. Engineers should evaluate RoHS compliance needs but will appreciate its reliability in harsh environments.
