RACF164DJT39R0

RACF164DJT39R0 Description

The RACF164DJT39R0 from Stackpole Electronics, Inc. is a 4-resistor network in a 1206 (3216 Metric) concave, long-side terminal package, designed for surface mount applications. This obsolete yet reliable component features a 39Ω resistance per element with a ±5% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The compact 0.126" x 0.063" (3.20mm x 1.60mm) footprint and 0.030" (0.75mm) profile make it ideal for space-constrained PCB designs. With 62.5mW power dissipation per resistor and an isolated circuit configuration, it offers robust performance in signal conditioning and voltage division applications.

RACF164DJT39R0 Features

• High-Density Integration: Combines 4 isolated resistors in a single 1206 package, reducing board space and assembly complexity.
• Stable Performance: ±200ppm/°C temperature coefficient ensures minimal resistance drift under thermal stress.
• RoHS3 Compliance: Meets environmental standards, making it suitable for modern electronics.
• Concave Terminal Design: Enhances solder joint reliability and mechanical stability during mounting.
• MSL 1 (Unlimited): No moisture sensitivity concerns, simplifying storage and handling.
• Tape & Reel Packaging: Optimized for automated pick-and-place assembly processes.

RACF164DJT39R0 Applications

This resistor network excels in precision analog circuits, voltage dividers, and pull-up/pull-down networks in:

• Consumer Electronics: Signal conditioning in audio/video equipment.
• Industrial Controls: Sensor interfacing and feedback loops.
• Automotive Systems: ECU signal processing (non-safety-critical).
• Telecom Infrastructure: Impedance matching in RF modules.
  Its isolated design prevents crosstalk, making it ideal for multi-channel signal paths where independent resistor performance is critical.

Conclusion of RACF164DJT39R0

The RACF164DJT39R0 offers a balance of compact integration, stable performance, and ease of assembly, making it a practical choice for legacy or cost-sensitive designs. While obsolete, its RoHS3 compliance and robust construction ensure reliability in demanding applications. Engineers seeking a space-efficient, high-performance resistor array for analog or mixed-signal systems will find this component a viable solution despite its discontinued status.
