RACF324DJT51R0

RACF324DJT51R0 Description

The RACF324DJT51R0 is a 4-resistor network from Stackpole Electronics Inc's RACF series, designed for surface-mount applications in compact electronic assemblies. This obsolete yet reliable component features a 2010 (5025 Metric) concave package with long-side terminals, offering a 51Ω resistance per element at ±5% tolerance. Its isolated circuit type ensures independent resistor functionality, while the ±200ppm/°C temperature coefficient provides stable performance across varying thermal conditions. With a 125mW power rating per element and ROHS3 compliance, it meets modern environmental standards. The 0.028" (0.70mm) low-profile height and 5.08mm x 3.00mm footprint make it ideal for space-constrained designs.

RACF324DJT51R0 Features

• 4 isolated resistors in a single 8-pin package, reducing PCB footprint.
• Concave, long-side terminal design for improved solder joint reliability.
• Wide operating tolerance (±5%) and ±200ppm/°C thermal stability for consistent performance.
• 125mW power dissipation per resistor, suitable for low-power circuits.
• ROHS3 compliant and REACH unaffected, adhering to environmental regulations.
• MSL 1 (Unlimited) moisture sensitivity, ensuring ease of handling and storage.
• Tape & Reel (TR) packaging for automated assembly efficiency.
