Type 3 SMD spring contact for PCB surface mount grounding and EMI shielding applications. Tape-and-reel packaged for automated SMT pick-and-place assembly — reliable contact force with consistent electrical performance. At a 2.0 mm working height, this is the lowest-profile part in the Type 3 series — suited to board-to-enclosure gaps too shallow for the taller Type 3 variants.
Tape-and-reel packaged for automated SMT pick-and-place — compatible with standard reflow soldering processes and production lines.
Type 3 spring profile delivers reliable electrical contact between PCB pad and metal enclosure for consistent EMI suppression performance.
Provides a low-resistance grounding path from PCB to chassis or housing — the spring returns the same contact force at a given working height, without taking a permanent set.
Precision-formed spring geometry ensures consistent contact force against the mating surface for reliable electrical continuity.
Low-profile 3-type geometry suited to space-constrained PCB layouts where board-to-housing clearance is limited.
