Feed-Thru is a conductive material used to make electrical and mechanical connections between the conductive patterns on the opposite side of a PCB. Strain Relief bushings are bushings intended to relieve stress on electrical or mechanical devices.
Ferrite Shielding Beads (46 Companies)
Passive ferrite components used to suppress HF noise and EMI/RFI in electronic circuits. Beads employ the mechanism of high dissipation of HF current in a ferrite. Ferrite beads may also be called ferrite cores, shielding beads, etc.
Ferrules (29 Companies)
Ferrules are clamps, usually circular, that are used to hold fibers, wires, or posts together by crimping, swaging, or otherwise altering the ferrule to fit and permanently tighten onto the part it holds.
Fuse Clips & Holders (45 Companies)
Fuse holders are sockets or supports that allow users to easily replace the fuse contained within. Clips are terminal contacts on the holder for wiring into the circuit.
Grommets & Bushings (41 Companies)
Grommets and bushings are metal, plastic, or rubber rings inserted into holes made in another material-can buttress the hole and/or protect against sharp edges. Bushings are linings reducing friction/wear. May also be used to restrain mechanical parts.
Ground Clamps & Clips (21 Companies)
Ground clips and clamps are usually metal or plastic strips and clips that are designed to make electrical connections with a common circuit point or the ground.
Guide Rails (DIN Type) (19 Companies)
DIN guide rails (top-hat rails) are standardized 15, 35, and 75 mm rails used most often in Europe. They are good for mounting circuit breakers and industrial control systems into equipment racks.
Heat Sinks Insulators (21 Companies)
Products, materials that protect against or help dissipate heat.
Insulation Material is used for thermal control, soundproofing, fireproofing, and shock-proofing. Most are made from conductive and convective insulators, radiant heat barriers and synthetic polymers. They come in spray foams, blankets and rigid panels.
Laminates & Substrates (59 Companies)
A material on the surface of which an adhesive substance is spread for bonding or coating. This supporting material on or in which the parts of an integrated circuit are attached or made. The substrate may be passive or active.
Magnetic Shields (35 Companies)
Magnetic shields are enclosures, material, metal sheets, or foils that help to protect electronics from the influences of external magnetic fields. Used in MRI equipment, monitors, CRTs, medical instrumentation, R&D experiments, etc.
Mounting Hardware (42 Companies)
Brackets are mounting devices normally made of metal, wood, and occasionally stone. When attached to a wall, they form a right angle, on which a shelf or other device can be placed to hold weight.

RF Shields (64 Companies)
Able to reduce coupling of radio waves, EM and electrostatic fields to the enclosed electronic devices. Holes in metal shield/mesh must be much smaller than wavelength of the radiation, or the shield will not approximate an unbroken conducting surface.
Shielding Kits (25 Companies)

Shrinkable caps, forms, and tapes have the ability to undergo changes in size when heated and cooled. The caps, forms, and tapes are available in a variety of sizes and shapes and the amount of shrinking is proportional to the increase in temperature.
Spacers & Standoffs (47 Companies)
Standoffs and Spacers are used to separate two components from each another. They can be made of many different materials in various shapes and sizes. Insulating Standoffs keep two parts from touching each other, thereby preventing an electronic short.

Strain Relief Bushings (10 Companies)
Strain relief bushings are bushings intended to relieve the stress on an electrical or mechanical device or part. By inserting a bushing in a hole, the tension on the component passing through the opening is lessened and weight is evenly distributed.
Magnetic Tape is a medium for magnetic recording consisting of a thin magnetized coating on a long and narrow strip of plastic. A Foil is a surface designed to maximize lift while minimizing drag. Foils may be designed to operate in air or water.
Thermal and semiconductor mounting pads are insulators of relatively low heat conductive material that are used to reduce the mounting surface of a semiconductor against thermal gain, or loss, of heat by radiation, convection, or conduction.
Thermal interface materials/mastics (TIMs) are used to fill the gaps in thermal transfer surfaces to increase thermal transfer efficiency. They come in thermal pastes and greases or in phase-changing materials.
