RACF164DJT3K90

RACF164DJT3K90 Description

The RACF164DJT3K90 from Stackpole Electronics, Inc. is a 4-resistor network array designed for high-density surface-mount applications. This obsolete but REACH-unaffected component features isolated resistors with a resistance value of 3.9kΩ (±5% tolerance) and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying thermal conditions. Encased in a 1206 (3216 Metric) concave long-side terminal package, it measures 0.126" x 0.063" (3.20mm x 1.60mm) with a low profile of 0.030" (0.75mm), making it suitable for space-constrained PCB designs. The array is RoHS3 compliant, rated for 62.5mW power per element, and packaged in Tape & Reel (TR) for automated assembly efficiency.

RACF164DJT3K90 Features

• Compact Design: Concave long-side terminals in a 1206 footprint optimize PCB space utilization.
• Stable Performance: Low ±200ppm/°C thermal drift ensures reliability in temperature-sensitive applications.
• High Compatibility: MSL 1 (Unlimited) moisture sensitivity allows extended storage without baking.
• Automation-Ready: Tape & Reel packaging supports high-speed pick-and-place assembly.
• Isolated Circuitry: Independent resistors reduce crosstalk, ideal for precision signal division.

RACF164DJT3K90 Applications

This resistor array excels in:

• Voltage Division Circuits: Precision attenuation in sensor interfaces or ADC front-ends.
• Consumer Electronics: Space-efficient designs in smart home devices or wearables.
• Industrial Controls: Stable performance in PLCs or motor drive feedback networks.
• Telecom Hardware: Signal conditioning in compact RF modules or baseband PCBs.

Conclusion of RACF164DJT3K90

The RACF164DJT3K90 balances miniaturization with performance, offering designers a reliable, space-saving solution for isolated resistor networks. While obsolete, its RoHS3 compliance, low thermal drift, and automation-friendly packaging make it a pragmatic choice for legacy or low-risk applications requiring consistent 3.9kΩ resistance. Its niche lies in cost-sensitive, high-volume production where standardized footprints and proven reliability are prioritized.
