Procurement Notes

Verify the specific ordering suffix and packaging configuration against the official TDK datasheet prior to procurement. Confirm that the component meets the required environmental certifications and RoHS compliance standards for your specific application. Ensure compatibility with standard surface-mount assembly processes and soldering profiles defined in the manufacturer's guidelines.

Selection Notes

Select this component when a 120 Ohm impedance at 100 MHz is required for signal integrity management. The 500mA current rating suits moderate power applications. Consider the 0805 package size for board layout constraints. Verify thermal performance under continuous load conditions to ensure operation remains within the -55°C to +125°C specification without derating issues.
