TE Connectivity 1551572-5

Product Overview

Spring fingers, also known as shield fingers, grounding springs, universal ground contacts, or antenna clips, are single-contact, surface-mountable internal connectors with multiple functions on a Printed Circuit Board (PCB). They are used in various small PCB applications across all industries for antenna feeds, low voltage electrical connections, and grounding or shielding. Spring fingers are beneficial in preventing EMI noise and static caused by vibrations from components like speakers, motors, and microphones. TE Connectivity (TE) offers a broad range of styles, heights, and materials to meet diverse customer needs.
