Molex Subsidiary, Temp-Flex, introduces MediSpec Micro Extrusion Primary Wires

MX0686 - Primary WireDesigned for medical applications requiring densely packaged surgically implantable leads, pin-hole free primary wires deliver precise electrical functionality and biocompatibility

Temp-Flex™ LLC, a subsidiary of Molex Incorporated, introduces its MediSpec™ micro extrusion primary wires.  Designed to meet tight tolerance requirements for invasive and implantable medical applications, Temp-Flex MediSpec micro extrusion primary wires deliver optimal reliability down to 52 AWG in a wide range of biocompatible conductor materials.

“Designers and manufacturers of surgically implanted medical devices require leads made of primary wires that meet stringent design requirements and reliability standards,” states Peter Evans, general manager, Temp-Flex. “Biocompatible insulated Temp-Flex MediSpec primary wires undergo an innovative extrusion process that results in superior dielectric integrity compared to other technologies.”

Now available in a 52 AWG construction, the primary wires feature a range of gauges (36-52 AWG) and a wide selection of materials to support design customisation.  The precision extrusion process used in manufacturing Temp-Flex MediSpec micro extrusion primary wires ensures uniform insulation wall thickness and accurate concentricity.  Encapsulating the wire within a consistent wall coating, the resulting pin-hole free wire offers superior reliability over similar products with emulsion and dispersion coatings that are susceptible to cracking.  The chemically inert insulation is impervious to surgical fluids and ensures biocompatibility in a human body.

Now available in insulation wall thicknesses down to 0.008 mm, Temp-Flex MediSpec micro extrusion primary wires are designed for neurological, cochlear and other implantable applications, in addition to minimally invasive endoscopes and catheters, and for use in cardio rhythm management devices including pacemakers and defibrillators. MediSpec primary wires are the foundation for MediSpec Micro Miniature Coils.

“Pin-hole free MediSpec primary wires deliver precision electrical functionality and biocompatibility – an ideal solution for customers developing densely packaged surgically implantable leads in a variety of medical applications,” adds Evans.

The MediSpec portfolio supports medical device manufacturers by delivering the latest interconnect technologies for maximum product efficiency, reliability and flexibility.  For more information about Temp-Flex MediSpec micro extrusion primary wires visit  To receive information about other Molex products and industry solutions, please sign up for our e-nouncement newsletter at
