RACF164DJT220K

RACF164DJT220K Description

The RACF164DJT220K is a high-density, surface-mount resistor network from Stackpole Electronics Inc's RACF series, designed for compact PCB applications. This 4-resistor array integrates isolated 220kΩ resistors (±5% tolerance) in a 1206 (3216 Metric) concave package with long-side terminals, optimizing space efficiency. With a 62.5mW power rating per element and a ±200ppm/°C temperature coefficient, it balances stability and performance in moderate-power circuits. The RoHS3-compliant device is packaged in Tape & Reel (TR) for automated assembly, featuring an MSL 1 (Unlimited) rating for moisture resistance.

RACF164DJT220K Features

• Compact Design: 3.20mm x 1.60mm footprint and 0.75mm profile suit high-density layouts.
• Reliable Performance: ±5% tolerance and 200ppm/°C TCR ensure consistent operation in varying temperatures.
• Isolated Circuitry: Independent resistors reduce crosstalk, ideal for precision signal conditioning.
• Automation-Friendly: TR packaging and concave terminal design enhance pick-and-place efficiency.
• Compliance: Meets REACH and RoHS3 standards, with EAR99 and HTSUS 8533.21.0020 classifications for global use.

RACF164DJT220K Applications

• Signal Division/Attenuation: Voltage dividers in sensor interfaces or ADC front-ends.
• Pull-Up/Down Networks: Bus termination or logic level stabilization in digital circuits.
• Industrial Controls: PLCs and automation systems requiring stable resistor arrays.
• Consumer Electronics: Space-constrained devices like wearables or IoT modules.
• Legacy System Maintenance: Suitable for obsolete-design replacements due to its discontinued status.

Conclusion of RACF164DJT220K

The RACF164DJT220K excels in applications demanding miniaturization, isolation, and moderate power handling. Its concave terminal design improves solder joint reliability, while the 1206 package balances size and manufacturability. Though obsolete, it remains a pragmatic choice for legacy designs or cost-sensitive projects requiring proven performance. Engineers should evaluate alternatives for new designs but can leverage this array for repairs or low-volume production.
