ATV321CR-072DBL

Attenuators Overview

The YAGEO ATV321CR-072DBL is a chip resistor RF attenuator designed for surface-mount applications. It provides a nominal attenuation of 2 ±0.3 dB, ensuring precise signal level control in radio frequency circuits. The component utilizes a compact 0404 (1010 metric) package, facilitating integration into space-constrained PCB layouts. Supplied in a 7-inch tape reel format, this device supports automated assembly processes. It is constructed to meet RoHS compliance standards, making it suitable for environmentally conscious electronic designs requiring reliable RF performance.

Attenuators Feature Summary

• Provides fixed 2 dB attenuation for RF signal management
• Utilizes compact 0404 surface-mount package for high-density layouts
• Designed for automated pick-and-place assembly via tape reel supply

Attenuators Applications

• RF signal path attenuation in communication modules
• Impedance matching networks in wireless devices
• Signal conditioning in test and measurement equipment

Attenuators Procurement Notes

Verify the specific ordering suffix 'L' confirms the 7-inch tape reel packaging configuration as documented in the manufacturer datasheet. Ensure that the required attenuation tolerance of ±0.3 dB aligns with the circuit design specifications before procurement. Confirm RoHS compliance status if environmental regulations are a strict constraint for the final product assembly.

Attenuators Selection Notes

Select this component when a fixed low-value attenuation is required in an RF chain. The 0404 footprint offers a smaller alternative to standard 0603 or 0805 packages. Consider the power handling capabilities inherent to thin-film attenuators in this size. Verify that the operating frequency range of the application falls within the effective performance limits of the 2 dB attenuator structure.

Attenuators Part Context

This part belongs to the ATV321 series of chip resistors specifically engineered as RF attenuators by YAGEO Corporation. These components bridge the gap between standard passive resistors and complex active RF circuits. The series is characterized by stable attenuation values across defined frequency bands, serving as fundamental building blocks for signal integrity management in modern electronics.

Attenuators Replacement Considerations

Panasonic Industry EXB-24AT2AR3X is identified as a parameter-equivalent substitute. Verify mechanical footprint compatibility and electrical performance equivalence before substitution.
