RACF648RJT4K70

RACF648RJT4K70 Description

The RACF648RJT4K70 from Stackpole Electronics, Inc. is a high-performance 8-resistor bussed network designed for precision surface-mount applications. Encased in a compact 2512 (6432 Metric) concave package with long-side terminals, it offers a 4.7kΩ resistance per element with a ±5% tolerance and ±200ppm/°C temperature coefficient. With a 62.5mW power rating per resistor and a low-profile 0.028" (0.70mm) seated height, this RoHS3-compliant network is ideal for space-constrained designs. Its bussed circuit configuration simplifies PCB layout by connecting resistors in a single common node, reducing component count. The Tape & Reel (TR) packaging ensures compatibility with automated assembly processes.

RACF648RJT4K70 Features

• Compact Design: Measures 0.252" x 0.122" (6.40mm x 3.10mm), optimizing board space.
• High Reliability: MSL 1 (Unlimited) moisture sensitivity ensures durability in humid environments.
• Stable Performance: ±200ppm/°C TCR minimizes resistance drift across temperature fluctuations.
• Efficient Power Handling: 62.5mW per resistor supports moderate power applications.
• Automation-Friendly: Concave terminals enhance solder joint reliability, while TR packaging streamlines pick-and-place assembly.
• Compliance: REACH unaffected and ROHS3 compliant, meeting global environmental standards.

RACF648RJT4K70 Applications

This resistor network excels in:

• Voltage Division Circuits: Precision dividers in sensor interfaces or ADC reference networks.
• Pull-Up/Pull-Down Arrays: Simplifies biasing for microcontrollers, FPGAs, or communication buses (e.g., I2C).
• Consumer Electronics: Dense PCBs in smart devices, wearables, and IoT modules.
• Industrial Controls: Signal conditioning in PLCs or motor drivers, where space and reliability are critical.
• Automotive Electronics: Non-safety-critical systems like infotainment, leveraging its robust construction.

Conclusion of RACF648RJT4K70
