This table only shows common product numbers. If the SB /SMB core you need is not listed in the above table, please do not hesitate to contact us. SB/SMB core can have the Gap process for electrical adjustment, the minimum gap is 0.1mm.

AL depends on material and gap; the grade prefix in the part number is the material the AL applies to (per EDD). Values without a prefix are reference values from the source table with the grade to be confirmed. C1/C2/Le/Ae/≈Wt per IEC 60205 from nominal dimensions; “/” = no effective-parameter data yet.
