Vishay Intertechnology, Inc. today announced that it has expanded its portfolio of Automotive Grade common mode chokes with four new surface-mount devices designed to improve system efficiency while saving board space. Offered in compact case sizes, the Vishay Dale ICM5050-A, ICM6050-A, IFLN-1210BE-A, and IFLN-1812CZ-A combine low DCR with high current capability and impedance.
Offering high temperature operation up to +150 °C, the AEC-Q200 qualified devices released today provide noise suppression and filtering for DC/DC power supplies, LCD displays, lighting drivers, in-vehicle Ethernet networks, and battery powered devices. While toroidal common mode chokes typically provide DCR of 23 mΩ, the ICM5050-A, ICM6050-A, IFLN-1210BE-A, and IFLN-1812CZ-A offer low DCR from 0.4 mΩ to 12 mΩ to reduce power losses and increase efficiency in these applications.
The ICM5050-A and ICM6050-A are wirewound ferrite common mode chokes that offer high current capabilities up to 11 A in the 5050 case size and 14 A in the 6050 case size. With footprints of 12.0 mm x 11.0 mm x 6.0 mm and 15.0 mm x 13.0 mm x 6.0 mm, respectively, the devices can save board space by replacing larger toroidal common mode chokes, which typically measure 19 mm x 30 mm x 28 mm.
The IFLN-1210BE-A and IFLN-1812CZ-A are ferrite common mode chokes with precision winding. The devices provide excellent common mode impedance up to 11 kΩ at 100 MHz in the compact 1210 and 1812 case sizes, making them ideal for suppressing EMI noise in CAN, LAN, and automotive DC/DC converters.
RoHS-compliant, halogen-free, and Vishay Green, all four devices are suitable for reflow soldering and compatible with automated pick and place assembly.
