M2 Lead Form Dimensions M2 Lead Bending Specifications The TO-202AB, TO-220AB, and TO-92 package configurations, because of their unique design, can be mounted in a variety of methods, depending upon heat sink requirements and circuit packaging methods. Any of the derived types shown in this section are available as standard parts direct from the factory. Custom package variations are available. Consult the factory for more information. Leads may be bent easily and may be bent to any desired angle, provided that the bend is made at a minimum 0.063" (0.1 for TO-218) away from the package body with a minimum radius of 0.032". DO-15X device leads may be bent with a minimum radius of 0.050", and DO-35 device leads may be bent with a minimum radius of 0.028". Leads should be held firmly between the package body and the bend, so that strain on the leads is not transmitted to the package body. To designate lead form options, simply indicate the type number at the end of the Teccor standard part number. Example: Q2004F312 (Signifies Type 12) Note: When ordering a TO-202 F package, include a 1 for standard full tab package. When ordering anything other than full tab, remove the 1 and add the Lead Form Type. When bending leads in the plane of the leads (spreading), bend only the narrow part. Sharp angle bends should be done only once, as repetitive bending will fatigue and break the leads. See “Description of Part Numbers” in the Product Selection Guide of this catalog for a complete description of Teccor part numbers. ©2004 Littelfuse, Inc.
