Tin-Lead Plated MLCCs for Aerospace and High-Reliability Applications Where Whisker Risk Matters
Johanson Dielectrics’ offers Tin Lead plated versions of all of our SMT MLCC products for high reliability, aerospace, and other applications where Tin whiskering is a concern. The plating is Tin Lead over Nickel barrier with 5% minimum Lead content. The Lead content of the plating in every manufacturing lot is verified using XRF method, and this data is available upon request. MIL-PRF-55681 and Hi Rel screened versions are also available. For values not shown please contact the factory.
