A MagSafe connector is held in place magnetically so that if it is tugged (for example, by someone tripping over the cable), it will be pulled out of the port without damaging the connector or the port, and without pulling the computer off its surface. [1] A thinner and wider version, called MagSafe 2, was introduced in 2012.
MagSafe is a proprietary, magnetically attached wireless power transfer and accessory-attachment standard developed by Apple Inc. for its iPhone and AirPods product lines. It was announced on October 13, 2020, in conjunction with the iPhone 12 and 12 Pro series.
Surface-mount technology (SMT), originally called planar mounting, [1] is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). [2] An electrical component mounted in this manner is referred to as a surface-mount device ( SMD ).
Variation of COB, where a chip is mounted directly to a flex circuit. Unlike COB, it may not use wires nor be covered with epoxy, using underfill instead. TAB: Tape-automated bonding: Variation of COF, where a flip chip is mounted directly to a flex circuit without the use of bonding wires. Used by LCD driver ICs. COG: Chip-on-glass
A thin layer of non-ferromagnetic material is applied to the reed switch contact area to serve as an electrical contact switching (wear) surface and, for normally-open contacts, as a magnetic spacer whose thickness is important in controlling the magnetic field level at which the contact opens (the drop-out).
The magnetic lock should always be installed on the secure side of the door. Most installations are surface mounted. For safety, magnetic lock, cables, and wires should be routed through the door frame or flush mount with wire moulding. Installation is straightforward.

An RF inductor wound on a ferrite core (not a ferrite bead), and a PCB mount ferrite bead A clamp-on ferrite bead heating up in operation. Ferrite beads are used as a passive low-pass filter by dissipating radio frequency (RF) energy as heat by design. Ideal inductors, on the other hand, have no resistance and hence do not dissipate energy as heat.
