Product details

Design Engineering Note

Mating and Termination

This shrouded 4-wall header mates with the matching Micro-Fit 3.0 receptacle housing (crimp terminals sold separately). The locking ramp engages audibly on full mate — no secondary lock required. Solder retention features on the SMT pads improve shear strength during reflow and resist cable strain after assembly. The LCP housing is rated UL94 V-0 and operates from -40°C to 105°C, covering automotive underhood and industrial cabinet duty without derating.
