Ordering
Specify packaging code
• Insert packaging code prefix before part number. E.g., BK (or BK1)-MDL-5-R
Specify option codes if desired
• For axial leads, insert “V” between catalog series and amp rating. E.g., BK-MDL-V-5-R
• For board washable, insert “B” between catalog series and amp rating. E.g., BK-MDL-B-5-R
• For axial leads and board washable, insert “B” then “V” between catalog series and amp rating. E.g., BK-MDL-BV-5-R
