	Your choices are...
	BMA / BMMA		BMA connectors feature a push-on interface and a thread less outer ground connection. They can withstand both radial and axial misalignment. BMMA connectors are miniature BMA connectors.
	BNC		Bayonet Neil-Councilman (BNC) connectors were designed for military applications, but are used widely in video and RF applications to 2 GHz. BNC connectors have a slotted outer conductor and a plastic dielectric that causes increasing losses at higher frequencies. BNC connectors are usable above 4 GHz as long as the slots radiate signals; however, these devices may not be mechanically stable to 10 GHz. Both 50Ω and 75Ω BNC connectors are available. BNC connectors are also known as bayonet navy connectors or baby Neil connectors.
	DVI		Digital video interface (DVI) connectors are used to transfer digital, audio or video signals.
	Type F		Type F connectors have a screw-type coupling and frequency range up to 1.5 GHz. Applications include CATV, TV, and antennas.

Terminations / Mounting


	Terminal Options		Terminals are devices designed to terminate a conductor to be affixed usually to a post, stud, chassis, or other conductor or the like in order to establish electrical connection.
	Your choices are...
	Cage Clamp		Electrical connections are made using a cage clamp.
	Crimp		Crimp is the physical compression (deformation) of a contact wire barrel around a conductor to make an electrical and mechanical connection to the conductor.
	IDC		Insulation displacement connectors (IDC) slice through the cable insulation to make a connection. Electrical connection is made when an insulated conductor is forced into a restrictive slot in the connection part of a contact, during which time the insulation is displaced, and the bare wire engages the sides of the slot. IDC are mass termination connectors for flat cables with contacts that displace the conductor insulation to complete termination. They eliminate the need to strip insulation.
	PCB Solder / Solder Pin		In PCB solder or solder pin termination, electrical connection is made by soldering wires or pins onto a printed circuit board (PCB).
	Screw		Electrical connections are made using screws.
	Screw-on or Lugs		Electrical connections are made using screw-on or lugs.
	Solder Cup		A solder cup is the end of a terminal or contact in which the conductor is inserted prior to being soldered. In solder cup terminations, soldering the connector onto the mounting location makes electrical connection.
	Tabs		Electrical connections are made through quick connect tabs.
	Through Hole / Pin		Through-hole technology (THT) mounts components on printed circuit boards by inserting component leads through holes in the board and then soldering. In pin termination, components are mounted on PCBs without soldering.
	Wire Wrap		Electrical connection is made by using a special tool to wrap a solid stripped or unstripped wire around a terminal post containing a series of sharp edges.
	Other		Other unlisted terminal types.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Bulkhead Mount		The connector has a plate (bulkhead) used to mount the device.
	Cable End		The connector is mounted at the end of an electrical cable.
	End Launch		End launch connectors are similar to right angle PC mounts in that the connector interface is parallel to the surface of the PC board. End launchers, however, are attached to the end or edge of the PC board by soldering.
	2-hole Flange Mount		Flange mounted connectors are attached to panels by bolting the flange or riveting it in place through the two holes in the flange surface.
	4-hole Flange Mount		Flange mounted connectors are attached to panels by bolting the flange or riveting it in place through the four holes in the flange surface.
	PC Mount		Connectors directly attach to the printed circuit board through pre-drilled holes in the board. Soldering permanently attaches connectors to PCB traces.
	Receptacle / Dummy Receptacle		Connectors with receptacle mounting are used in applications where the connector is required to fit a panel cutout. Dummy receptacles are receptacles that do not have provisions for attaching conductors. They are generally used for storage of a cable assembly connector plug.
	In-line or Cable Receptacle		Intended for cable connecting - typically mated with a straight or 90-degree plug.
	Jam Nut Receptacle		Intended for "D" shaped holes.
	Solder / Weld Mount Receptacle		Intended for higher-pressure systems and permanent mounting.
	Surface Mount (SMT)		Surface mount technology (SMT) places small components on the surface of a printed circuit board. Soldering permanently attaches connectors to PCB traces. Unlike PC mount connectors, however, SMT connectors do not require drilled holes in the PCB. Using smaller components allows for higher frequencies of operation, smaller board size, etc.
	Wall or Box Mount Receptacle		Typically flanged and threaded for an accessory (backshell) and intended for permanent mounting.
	Other		Other unlisted, specialized, or proprietary styles.
