Procurement Notes

Verify the specific axial bushing mounting requirements against the target chassis or panel thickness before ordering. Confirm that the 500V DC rating and 20A current capacity align with the system's electrical specifications. Ensure the X7R temperature characteristics meet the operational environment constraints. Cross-reference the physical dimensions with the official datasheet to guarantee mechanical fit within the assembly.

Selection Notes

Select this component when high-current EMI filtering is required in a compact axial form factor. The 500V rating suits medium-voltage power lines. Consider the bushing installation method for secure grounding. Compare against surface-mount alternatives if space constraints differ. Verify compatibility with the intended frequency spectrum for optimal attenuation performance.
