Vishay – Low DC resistance SMD common-mode chokes with rated currents up to 8A (ICM-2824)

Vishay has announced the release of three new surface-mount, common-mode chokes offering low DC resistance, high current-handling capability, and high stability for DC power lines.

The new ICM-2824, ICM-3528, and ICM-4743 common-mode chokes are designed to provide noise suppression for power line applications in local area networks (LAN), personal computers, CD-ROM drives, telephones, and electronic games.

The devices feature low maximum DC resistance from just 0.006ohm up to 0.015ohm at rated currents from 8A down to 4A, and common-mode impedance ranging from 300ohm to 1500ohm at 100MHz.

All three chokes provide a maximum rated voltage of 80VDC, insulation resistance of 10Mohm, and an operating temperature range of -25C to +85C.

Offered in lead- (Pb) free, surface-mount packages with treated base terminals, the devices allow for easy mounting to the PCB and feature a paired wire coil for high stability. The ICM-2824, ICM-3528, and ICM-4743 measure 7mm x 6mm, 9mm x 7mm, and 12mm x 11mm, respectively, with maximum heights of 4mm, 5mm, and 6.3mm, says the company.
