Procurement Notes

Verify the specific suffix configuration against official manufacturer documentation to confirm terminal type and termination material specifications. Ensure the selected variant matches the required dielectric characteristics and voltage ratings for the target application environment. Cross-reference the part number with current distributor catalogs to confirm availability status and lead times prior to order placement.

Selection Notes

Select this component when space-constrained designs require integrated filtering without additional discrete components. Consider the X7R dielectric properties for stability across the specified operating temperature range. Evaluate the mechanical flexibility of the terminations if the printed circuit board experiences significant bending or thermal cycling stress during operation.
