Attenuators Procurement Notes

Verify the specific ordering suffix AS3 against the manufacturer's current datasheet to confirm packaging configuration. Confirm RoHS compliance status and environmental documentation prior to integration. Ensure that the 1 W power rating aligns with the thermal management requirements of the target application environment.

Attenuators Selection Notes

Select this component when a precise 3 dB attenuation value is required within a 50 Ohm system up to 20 GHz. The 0603 footprint allows for dense PCB layouts. Consider the ±0.75 dB tolerance for critical signal path accuracy. The high-temperature capability makes it suitable for harsh industrial or automotive environments where standard components may fail.

Attenuators Part Context

This part belongs to the KYOCERA AVX AT series of thin-film RF attenuators. These components are engineered for broadband applications requiring stable attenuation values over wide frequency ranges. The series offers various attenuation values and packages, providing designers with flexible options for integrating passive RF control into modern electronic systems.

Attenuators Replacement Considerations

Cross-reference with other 0603, 3 dB, 20 GHz attenuators from manufacturers such as Mini-Circuits or Qorvo. Verify that substitute parts match the 50 Ohm impedance, 1 W power rating, and ±0.75 dB tolerance. Ensure the replacement component supports the same -55°C to +150°C operating temperature range.
