Procurement Notes

Verify the specific ordering suffix to confirm packaging type, such as tape and reel or bulk, as these affect handling procedures. Confirm compliance requirements including RoHS status against project specifications. Ensure the voltage rating meets circuit demands. Check lead times as they may vary based on production schedules. Validate that the axial package fits the designated footprint.

Selection Notes

Select this component when a low-value, high-tolerance resistor is required for standard current paths. The 2.4-ohm value suits current sensing or limiting roles. The 1/4W rating provides adequate dissipation for moderate loads. Consider the wide operating temperature range for environmental robustness. Verify compatibility with automated placement equipment if using reel packaging.
