400-50R-S

Attenuators Overview

The 400-50R-S is a high-frequency RF resistor manufactured by TTM Technologies. It operates within a frequency range of 0 Hz to 500 MHz and features a nominal resistance of 50 Ohms. Designed for robust performance, this component supports a power rating of 400W. The device utilizes a thick film resistive element on a Beryllium Oxide (BeO) substrate. It is housed in a flange mount package configuration suitable for board mounting applications.

Attenuators Feature Summary

• High power handling capability of 400W for demanding RF environments
• Thick film technology on BeO substrate for thermal stability
• Flange mount package design for secure board integration

Attenuators Applications

• High frequency circuit termination
• RF load applications
• Power absorption in microwave systems

Attenuators Procurement Notes

Verify the specific flange mount dimensions and thermal interface requirements against the official datasheet before integration. Confirm that the BeO substrate handling protocols align with facility safety standards due to toxicity risks if damaged. Ensure the 400W power rating is supported by the system's thermal management infrastructure under continuous operation conditions.

Attenuators Selection Notes

Select this component when high power dissipation at frequencies up to 500 MHz is required. The 50 Ohm impedance matches standard RF transmission lines. The flange mount style is preferred over surface mount variants for higher power levels. Consider the thermal conductivity of the BeO substrate for heat sinking strategies compared to alternative ceramic materials.
