2118715-4 is a two-piece board level shielding (BLS) cover component designed to provide electromagnetic interference (EMI) suppression and isolation of board-level components in compact electronic devices. The shield features dimensions of 16.90 mm × 16.90 mm × 2.00 mm with a material thickness of 0.15 mm, manufactured from aluminum or stainless steel with galvanized or pre-plated finishes. Key technical characteristics include a minimum pitch of dimples at 3 mm, an inner bending radius of 0.10 mm minimum, and co-planarity of 0.08 mm size-dependent, ensuring precise fit and performance. This component is ideal for applications requiring board-level EMI suppression in mobile phones, tablets, routers, wireless devices, IoT equipment, and other consumer electronics where space constraints and electromagnetic compatibility are critical design considerations.
