FIELD: radio engineering, communication.
SUBSTANCE: circuit protection device includes a printed-circuit board including a circuit element and an grounded frame surrounding the circuit element, a conductive body having an internal cavity for accommodating the circuit element, and a conductive adhesive layer located between the grounded frame and the conductive body to provide electrical connection between grounded frame and conductive body.
EFFECT: formation of a Faraday cage by combining a conductive body, an adhesive conductive layer and a grounded frame on a printed-circuit board for shielding electromagnetic radiation to eliminate or reduce the effect of electromagnetic radiation on the circuit element without increasing the weight and size of product with an additional shielding conductive coating.
