Product Features

Key Characteristics

◆

SMT Compatible

Tape-and-reel packaged for automated SMT pick-and-place — compatible with standard reflow soldering processes and production lines.

◆

EMI Shielding

C-type spring profile delivers reliable electrical contact between PCB pad and metal enclosure for consistent EMI suppression performance.

◆

PCB Grounding

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.

◆

Spring Contact Force

Precision-formed spring geometry ensures consistent contact force against the mating surface for reliable electrical continuity.

◆

Compact Profile

Low-profile C-type geometry suited to space-constrained PCB layouts where board-to-housing clearance is limited.
