04 · BUYER QUESTIONS

Frequently asked questions

Is this page for line-to-earth use?

No. This family is positioned for X2 across-the-line suppression; use an appropriate Y-class family for line-to-earth duty.

What does THB selection require?

Provide rated voltage, capacitance, humidity profile, case limit and applicable approval requirements.

Are certificates implied by the product page?

No. Applicable certification documents must be confirmed for the selected ordering code and destination market.

Can the case and lead pitch change?

Yes. Dimensions and lead spacing depend on capacitance and the approved ordering code.

RFQ checklist

Please provide capacitance, voltage, current or pulse duty, frequency, ambient temperature, case limit, PCB pitch, approval market, annual quantity and branding requirement.

Engineering confirmation

The product image is representative. Final marking, dimensions, electrical ratings and applicable documentation follow the approved part number, drawing and sample.
