Frequently Asked Questions

Which designs are a good fit for 400KXW100MEFC16X30 when 20% is required?

400KXW100MEFC16X30 is a polarized capacitor from Rubycon for power-rail decoupling, filtering, timing support, and noise suppression. The 20% specification helps engineers confirm electrical margin before adding it to a production BOM.

How should engineers check the footprint before placing 400KXW100MEFC16X30 on a PCB?

Review the Capacitor, Polarized Radial Diameter package information together with 2 pins before layout release. That check reduces substitution risk when matching land pattern, assembly process, and approved vendor data.

When would procurement choose 400KXW100MEFC16X30 instead of a nearby alternate?

Buyers should keep 400KXW100MEFC16X30 when the approved design depends on 400V and Capacitor, Polarized Radial Diameter compatibility. Alternate reviews should verify at least 1 matching electrical rating and footprint constraint.
