PAT0510S-C-7DB-T10

Overview

The PAT0510S-C-7DB-T10 is a high precision chip attenuator manufactured by Susumu, designed for surface mount applications in the 0402 package. It provides a nominal attenuation of 7 dB with a tolerance of ±0.5 dB across a frequency range of 0 Hz to 10 GHz. The component operates at a 50 Ohm impedance with a maximum VSWR of 1.3 and a power rating of 32 mW. It functions within an operating temperature range of -55°C to +125°C.

Feature Summary

• High precision silicon-based construction for stable RF signal attenuation
• Compact 0402 surface mount footprint suitable for space-constrained designs
• Wide operational bandwidth extending from DC to 10 GHz
• Robust thermal performance supporting operation up to +125°C

Applications

• RF signal conditioning in wireless communication modules
• Impedance matching networks in microwave circuits
• Signal level adjustment in test and measurement equipment
• Attenuation stages in radar and satellite systems

Procurement Notes

Verify the specific ordering suffix matches the required tolerance and packaging configuration. Confirm that the 0402 package dimensions align with the PCB layout constraints. Ensure the 32 mW power rating is sufficient for the intended application's signal levels. Check RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when precise attenuation values are critical for circuit performance. The 0.5 dB tolerance ensures consistent signal levels across production batches. Consider the 0402 size for high-density board layouts. Evaluate the 10 GHz frequency limit against the system's maximum operating frequency to ensure adequate performance margins.

Part Context

This part belongs to the PAT series of precision chip attenuators from Susumu. The series offers various attenuation values in standard 50 Ohm configurations. These components utilize silicon technology to provide reliable performance in RF and microwave applications. The PAT series is designed for SMT processes, facilitating automated assembly in modern electronics manufacturing.

Replacement Considerations

Compatible substitutes include other 0402 7 dB 50 Ohm attenuators from manufacturers such as Murata or Johanson Technology. Verify that alternative parts match the 0.5 dB tolerance and 32 mW power rating. Ensure the replacement maintains the same 0 Hz to 10 GHz frequency range and VSWR specifications.
