GQCA034301BT

GQCA034301BT Description

The GQCA034301BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 4.3K Ohm resistance and an ultra-tight tolerance of 0.1%. Encased in a ceramic package, it offers excellent thermal stability and durability, with a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) compatibility, while the ±25ppm/°C temperature coefficient guarantees minimal resistance drift across a wide temperature range (70°C to 125°C). With a power rating of 1W total (0.1W per resistor) and a maximum voltage rating of 100V, this network is ideal for precision analog and digital circuits.

GQCA034301BT Features

• High Precision: 0.1% tolerance and ±25ppm/°C TCR ensure consistent performance in critical applications.
• Robust Construction: Ceramic case provides superior thermal and mechanical stability.
• Isolated Design: 12 resistors with isolated circuit design (ISOL) reduce crosstalk and interference.
• Surface-Mount Ready: Gull-wing terminals and QSOP package enable easy PCB integration.
• Wide Operating Range: Functions reliably from 70°C to 125°C with derated power handling.
• High Voltage Tolerance: Supports up to 100V, making it suitable for industrial and automotive-grade systems (though not PPAP or Automotive certified).
