Procurement Notes
Verify the specific suffix MX0 against the official datasheet to confirm terminal plating and sealing specifications. Ensure the 50VDC rating aligns with circuit requirements. Confirm compliance with RoHS directives if mandated by project standards. Cross-reference the axial lead dimensions with mechanical constraints before integration.
Selection Notes
Select this component when low-profile axial filtering is required for 50V circuits. The C0G dielectric ensures minimal capacitance drift under varying conditions. Compare the 0.033uF value against alternative series like SFSWR or SFCML if higher voltage ratings or different termination styles are needed. Validate thermal limits against the operational environment.
