Vishay Intertechnology Introduces Three New Surface-Mount, Common-Mode Chokes With High Rated Currents to 8.0 A and Low DC Resistance Down to 0.006 Ω
MALVERN, Pa. — Nov. 29, 2011 — Vishay Intertechnology, Inc. (VSH: NYSE) today 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 from Vishay Dale 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 released today feature low maximum DC resistance from just 0.006 Ω up to 0.015 Ω at rated currents from 8.0 A down to 4.0 A, and common-mode impedance ranging from 300 Ω to 1500 Ω at 100 MHz. All three chokes provide a maximum rated voltage of 80 VDC, insulation resistance of 10 MΩ, and an operating temperature range of - 25 °C to + 85 °C.
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 7 mm by 6 mm, 9 mm by 7 mm, and 12 mm by 11 mm, respectively, with maximum heights of 4 mm, 5 mm, and 6.3 mm.
Device Specification Table:
|Part number||Impedance @ 100 MHz||Rated current max.||DC resistance max.|
|ICM-2824||300 Ω||5.0 A||0.01 Ω|
|700 Ω||4.0 A||0.015 Ω|
|ICM-3528||700 Ω||5.0 A||0.01 Ω|
|1500 Ω||4.5 A||0.015 Ω|
|ICM-4743||700 Ω||8.0 A||0.006 Ω|
|1000 Ω||6.0 A||0.014 Ω|
Samples and production quantities of the new common-mode chokes are available now. Lead time for production quantities is 10 weeks.
