Jumper Leads
FLEXSTRIP® jumpers are multi-conductor board- to -board interconnect devices. They provide a convenient, reliable alternative to conventional point to point wiring for high density, high vibration PCB interconnections. Two types are available: those made from Nomex material are suitable for standard applications where changes of direct resistance due to humidity are not critical; those made from PTFE are ideal for high electrical and mechanical performance applications.
