In the standard offerings, Category A or the first digit refers to the series which is defaulted as “M”. The following 2nd and 3rd digits are Category B which defines the base profile of the Max Clip part. Digits 4‐6, Category C refers to cut length. The decimal point is assumed between the 4th and 5th digit. Standard parts for the Max Clip parts can be quoted in lengths under 10” any longer lengths will be quoted custom. Category D is digit 7 and refers to the finish, followed by digit 8 or Category E which defines the thermal interface material. The 9[th] and 10[th] digits or Category F calls out the number of pins and the pin type for board mounting. The last sequence of the part number are the device mounting or Category G, digits 11‐13 and refer to the number of clips and the Max Clip type. - A (Digits 1) = Series name M B (Digits 2‐3) = Base Profile C (Digit 4‐6) = Cut Length D (Digit 7) = Finish E (Digits 8) = Thermal Interface Material F (Digits 9‐10) = Board Mounting G (Digit 11‐13) = Device Mounting H (Digits 14) = RoHS Compliant ## M 45 225 B 0 21 103 G **A B C D E F G H** ## **CATEGORY B ‐ DIGITS 2‐3: BASE PROFILE** ## **CATEGORY C – DIGIT 4‐6: CUTTING OPTIONS** |**Code**|**Base Extrusion**|**Height**|**Width**|**Dual Mount**| |---|---|---|---|---| |45|78020|51.00 (2.008 in)|30.00 (1.181 in)|Y| |46|78060|48.36 (1.904 in)|30.00 (1.181 in)|N| |47|78065|30.80 (1.212 in)|18.85 (0.742 in)|N| |48|78240|38.58 (1.519 in)|21.94 (0.864 in)|N| |49|78265|31.36 (1.235 in)|22.00 (0.866 in)|N| The cut length option is limited to lengths under 10” and can be up to two decimals places.
