RACF324DJT1K80

RACF324DJT1K80 Description

The RACF324DJT1K80 is a high-performance resistor network from Stackpole Electronics Inc's RACF Series, designed for precision surface-mount applications. This 4-resistor array features isolated circuit topology with a 1.8kΩ resistance per element, offering a ±5% tolerance and ±200ppm/°C temperature coefficient for stable operation across varying thermal conditions. Encased in a compact 2010 (5025 Metric) concave long-side terminal package, it measures 0.200" x 0.118" (5.08mm x 3.00mm) with a low-profile 0.028" (0.70mm) height, making it ideal for space-constrained PCB designs. The device is RoHS3 compliant and REACH unaffected, ensuring environmental and regulatory compatibility.

RACF324DJT1K80 Features

• 4 isolated resistors in a single 8-pin package, reducing board space and assembly complexity.
• 125mW power rating per element, suitable for moderate-power applications.
• Concave long-side terminals enhance solder joint reliability and mechanical stability.
• Tape & Reel (TR) packaging for automated pick-and-place assembly efficiency.
• Moisture Sensitivity Level (MSL) 1 (Unlimited), allowing extended floor life without dry storage requirements.
• Wide operating temperature range supported by a robust ±200ppm/°C thermal coefficient.

RACF324DJT1K80 Applications

This resistor network excels in precision analog/digital circuits, including:

• Voltage dividers and pull-up/pull-down networks in microcontrollers and FPGAs.
• Signal conditioning for sensors and data acquisition systems.
• Impedance matching in communication modules (e.g., RF, IoT devices).
• Power supply feedback loops requiring stable resistance values.
  Its obsolete status may limit new designs but remains viable for legacy system maintenance or inventory-driven projects.

Conclusion of RACF324DJT1K80

The RACF324DJT1K80 combines compactness, reliability, and moderate power handling, making it a versatile choice for embedded systems and industrial electronics. While obsolete, its concave terminal design and isolated resistor configuration provide distinct advantages over flat-terminal arrays in vibration-prone environments. Engineers should evaluate alternative active-series parts for new designs but can leverage this model for cost-effective repairs or proven circuit replication.
