RACF648RJT2K20

RACF648RJT2K20 Description

The RACF648RJT2K20 is an 8-resistor bussed network array from Stackpole Electronics Inc, designed for high-density surface-mount applications. Part of the RACF series, it features a compact 2512 (6432 Metric) concave package with long-side terminals, measuring 0.252" x 0.122" (6.40mm x 3.10mm) and a low-profile height of 0.028" (0.70mm). Each resistor offers a 2.2kΩ resistance with a ±5% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The array is rated for 62.5mW power per element and is RoHS3 compliant, meeting modern environmental standards.

RACF648RJT2K20 Features

• High-Density Integration: Combines 8 resistors in a single 2512 package, saving PCB space.
• Concave, Long-Side Terminals: Enhances solder joint reliability and mechanical stability.
• Wide Operating Range: Suitable for applications with ±200ppm/°C thermal stability.
• Surface-Mount Design: Optimized for automated assembly processes (Tape & Reel packaging).
• Low Moisture Sensitivity (MSL 1): Ideal for environments requiring extended shelf life or minimal baking.
• Bussed Circuit Configuration: Simplifies design for common-node applications like pull-up/pull-down networks.

RACF648RJT2K20 Applications

This resistor array excels in:

• Voltage Division Circuits: Precision dividers in sensor interfaces or ADC reference networks.
• Signal Conditioning: Termination or impedance matching in communication modules (e.g., IoT devices).
• Consumer Electronics: Space-constrained designs like wearables or compact PCBs.
• Industrial Controls: Robust performance in PLCs or motor drives due to its REACH unaffected status.
• Power Management: Distributed decoupling or bias networks in power supplies.

Conclusion of RACF648RJT2K20

The RACF648RJT2K20 balances compactness, reliability, and performance, making it a versatile choice for modern electronics. While obsolete, its ROHS3 compliance, low-profile design, and bussed architecture remain advantageous for legacy or niche applications requiring standardized resistor networks. Engineers should evaluate alternative RACF-series models for active designs but can leverage this array for cost-effective, high-volume production where its specifications align.
