Procurement Notes

Verify the specific impedance tolerance and current ratings against your circuit requirements before procurement. Confirm that the 0402 package dimensions align with your PCB layout constraints. Ensure compatibility with your assembly process regarding surface mount technology standards. Cross-reference the manufacturer datasheet for detailed handling and storage instructions to maintain component integrity during installation.

Selection Notes

Select this component when a 70 ohm impedance at 100 MHz is required for noise filtering in small form factor designs. Consider the 800 mA current rating to ensure it meets the operational load without saturation. Evaluate the low DC resistance to minimize voltage drop in power lines. Verify that the ±25% tolerance range fits within your system's noise margin specifications for reliable performance.
