GQ8B0146R4FT Description

The GQ8B0146R4FT from TT Electronics/IRC is a high-precision thin-film resistor network designed for surface-mount applications requiring stable performance in demanding environments. This 16-pin QSOP package integrates 15 resistors with a 46.4Ω resistance value, offering a tight 1% tolerance and a low ±100ppm/°C temperature coefficient. The ceramic case ensures excellent thermal stability, while the gull-wing termination facilitates reliable PCB mounting. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is engineered for high-density circuits where space and reliability are critical.

GQ8B0146R4FT Features

• Precision Thin Film Technology: Delivers superior accuracy (±1%) and low TCR (±100ppm/°C) for stable performance across 70°C to 125°C.
• Robust Ceramic Construction: Enhances thermal management and mechanical durability in harsh conditions.
• High-Density QSOP Package: Compact 4.9mm × 6.02mm × 1.47mm footprint with 0.64mm pitch, ideal for space-constrained designs.
• BUS Circuit Designator: Optimized for bus termination, voltage division, and pull-up/down applications.
• Non-Automotive, Non-PPAP: Suitable for industrial, telecom, and instrumentation use where automotive compliance is not required.
• Non-RoHS (Not Compliant): May be preferred for legacy or specialized applications exempt from RoHS restrictions.
