L-1011-12 CHOMERICS, L-1011-12 Datasheet

FEATURES

• Low RF impedance

• Passes all requirements of UL

• Reduces EMI radiated emissions

• Very flexible

• Simple installation

• Tinned contacts for corrosion resistance

• Flame retardant adhesive system

• High dielectric strength exterior

• Wide range of standard sizes

CHO-STRAP ® grounding straps are flex-

ible, double-insulated laminates of copper

(inside) and polyester film (outside), with

punched and tinned ends to facilitate

termination. They provide low-impedance

ground paths at RF frequencies, thereby

reducing radiated EMI problems caused by

ordinary wire grounds. They are generally

more cost-effective than braided ground

straps.

wherever board-to-chassis or chassis-to-

cabinet grounding is required. Common

applications include:

• Tying a CRT driver board to chassis

• Tying one sub-chassis to another;

• Tying a sub-chassis to main chassis

• Tying cabinet panels to chassis

#18 copper wire) will have high impedance

at RF frequencies, and can actually act as

an antenna, thereby increasing radiated

emission levels. Braided ground straps are

costly and inconvenient because their ends

generally require tinning or hole punching

by the user, and they must often be insu-

lated to avoid shorting problems in tight

quarters.

in a variety of standard widths and lengths

(see Table 1). Standard construction is

5-oz. rolled annealed copper, laminated on

both sides to 1-mil polyester film with a

flame retardant polyester adhesive. Ends

are punched with 0.187” dia. holes (4.75

mm dia.) for ease of installation with #10

screws. A 1/2” (12.7 mm) tinned area at

each end prevents oxidation of the

termination contact area.

Other sizes available.
