Procurement Notes

Verify the specific suffix 'J' confirms the ±5% tolerance and 'K' indicates the axial leaded package configuration. Confirm compliance with RoHS3 directives and REACH regulations during sourcing. Ensure the manufacturer part number matches exactly to avoid confusion with similar series components like RSF or RSMF variants that may differ in power ratings or coatings.

Selection Notes

Select this component when a 5W power rating and 330 Ohm resistance are required in an axial form factor. Consider its wide operating temperature range up to 235°C for high-heat environments. The metal oxide construction offers superior stability compared to carbon composition types, making it suitable for precision applications where thermal drift must be minimized under load.
