Type S-03 SMD spring contact for PCB surface mount grounding and EMI shielding applications. The Precision-formed spring geometry provides consistent contact force while tolerating board-level variations — ideal for RF modules, shielding cans, and PCB-to-enclosure grounding.
Tape-and-reel packaged for automated SMT pick-and-place — compatible with standard reflow soldering processes and production lines.
Type S 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.
Type S geometry suited to space-constrained PCB layouts where board-to-housing clearance is limited.
