RACF648RJT10K0

RACF648RJT10K0 Description

The RACF648RJT10K0 from Stackpole Electronics Inc is an 8-resistor bussed network array designed for high-density surface-mount applications. Housed in a compact 2512 (6432 Metric) concave long-side terminal package, it offers a 10kΩ 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 array is ideal for space-constrained designs. The ROHS3-compliant and REACH-unaffected device is supplied in Tape & Reel (TR) packaging, ensuring compatibility with automated assembly processes. Though marked as Obsolete, its robust performance and standardized footprint make it a reliable choice for legacy or low-risk applications.

RACF648RJT10K0 Features

• High-Density Integration: 8 resistors in a single 2512 package (6.40mm x 3.10mm) reduce PCB footprint.
• Stable Performance: ±200ppm/°C thermal stability ensures reliability across temperature variations.
• Automation-Friendly: Tape & Reel (TR) packaging supports high-volume pick-and-place assembly.
• Low-Profile Design: 0.028" (0.70mm) max height suits thin or multilayer PCB designs.
• Bussed Circuit Configuration: Simplifies layout for common-node applications like pull-up/down networks.
• Compliance: ROHS3 and REACH compliant, with MSL 1 (Unlimited) moisture sensitivity for extended shelf life.

RACF648RJT10K0 Applications

• Voltage Division: Precision divider networks in sensor interfaces or ADC circuits.
• Pull-Up/Down Arrays: Simplifies biasing for microcontrollers, FPGAs, or communication buses (I2C, SPI).
• Legacy Systems: Maintenance or repair of older electronics where obsolescence is manageable.
• Power Management: Signal conditioning in low-power DC/DC converters or load-sharing circuits.
• Industrial Controls: Durable performance in -55°C to +125°C environments, suitable for PLCs or motor drives.

Conclusion of RACF648RJT10K0

The RACF648RJT10K0 resistor network balances compactness, stability, and ease of integration, making it a pragmatic choice for bussed-resistor applications. While obsolete, its standardized 2512 footprint and 62.5mW power handling ensure backward compatibility. Ideal for designers prioritizing space efficiency and batch assembly, it remains a viable solution for industrial, automotive, and consumer electronics where thermal drift and density are critical. For new designs, verify alternatives, but for legacy support, this array delivers proven performance.
