AT0603C10ECAC7

Attenuators Overview

The AT0603C10ECAC7 is a fixed RF/microwave attenuator manufactured by KYOCERA AVX. It provides a nominal attenuation of 10 dB with a tolerance of ±0.75 dB. The component operates within a frequency range from DC to 20 GHz and maintains a characteristic impedance of 50 Ohms. It features a maximum Voltage Standing Wave Ratio (VSWR) of 1.25. The device is rated for a power handling capacity of 0.75 W, although some sources cite 1 W. It utilizes surface mount technology in a 0603 (1608 metric) package. The operational temperature range spans from -55°C to +150°C.

Attenuators Procurement Notes

Verify the specific power rating classification, as documentation varies between 0.75 W and 1 W for this part number. Confirm the manufacturing origin and lot traceability requirements prior to ordering. Ensure that the 0603 package dimensions align with the target PCB land pattern specifications. Check for RoHS compliance status if environmental regulations apply to the end product. Request updated datasheets directly from KYOCERA AVX to confirm current production status and any recent parameter updates.

Attenuators Selection Notes

Select this component when a fixed 10 dB attenuation is required across a broad DC to 20 GHz bandwidth. The 50 Ohm impedance matches standard RF transmission lines. Consider the 0603 size constraint for space-limited designs. Evaluate the thermal management capabilities given the +150°C maximum operating temperature. Compare against other series members like the AT0603T03ECAC7 if different attenuation values are needed.

Attenuators Part Context

This part belongs to the KYOCERA AVX AT series of ceramic chip attenuators. These components are designed for high-reliability applications in the wireless and microwave sectors. The series offers various attenuation values and power ratings in standardized SMT packages. The AT0603C10ECAC7 specifically addresses the need for compact, high-frequency signal attenuation solutions.

Attenuators Replacement Considerations

Direct substitutes include other KYOCERA AVX models with identical 10 dB attenuation and 0603 packaging, such as variations in the AT0603 series. Cross-brand replacements require matching the 50 Ohm impedance, 20 GHz frequency limit, and physical dimensions. Verify that alternative parts meet the same VSWR and power handling specifications.
