CRA04S08318R0FTD

CRA04S08318R0FTD Description

The CRA04S08318R0FTD from Vishay Dale is a high-precision, surface-mount resistor network designed for compact electronic applications. Part of the CRA04 series, this 4-resistor array features an 18Ω resistance per element with a tight ±1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. Encased in an 0804 convex long-side terminal package, it measures just 2.00mm x 1.00mm (L x W) with a 0.55mm profile, making it ideal for space-constrained PCB designs. The isolated circuit configuration allows independent resistor operation, while its 62.5mW power rating per element balances efficiency and reliability.

CRA04S08318R0FTD Features

• Compact Design: Ultra-thin 0.022" (0.55mm) height and miniature footprint for high-density layouts.
• Precision Performance: ±1% tolerance and ±100ppm/°C TCR for consistent signal integrity.
• Robust Construction: ROHS3-compliant and MSL1 (unlimited) rated for environmental resilience.
• Efficient Packaging: Supplied in tape & reel (TR) for automated assembly compatibility.
• Versatile Configuration: Isolated resistors enable flexible circuit design without crosstalk.

CRA04S08318R0FTD Applications

This resistor array excels in precision analog and digital circuits, including:

• Voltage dividers and pull-up/pull-down networks in microcontrollers.
• Signal conditioning for sensors and IoT devices.
• Impedance matching in high-frequency communication systems.
• Consumer electronics (e.g., wearables, smartphones) requiring miniaturized components.
  Its obsolete status suggests replacement planning but remains viable for legacy designs.

Conclusion of CRA04S08318R0FTD

The CRA04S08318R0FTD combines precision, compactness, and reliability, making it a strong choice for applications demanding tight tolerances and space efficiency. While obsolete, its Vishay Dale pedigree ensures quality for existing deployments. Engineers should evaluate alternatives for new designs but can leverage its isolated 4-resistor architecture and 0804 form factor for legacy or niche requirements.
