Vishay Intertechnology Releases Commercial Version of the Popular Automotive Grade IHLE Integrated E-Shield Inductor available in 2525, 3232, and 4040 Case Sizes, Devices Provide -20 dB Electric Field Reduction at 1 cm.
MALVERN, Pa. — Jan. 16, 2017 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced a commercial version of its popular Automotive Grade IHLE series of low profile, high current inductors featuring integrated e-shields for EMI reduction. Available in the 2525, 3232, and 4040 case sizes, the Vishay Dale IHLE-2525CD-51, IHLE-3232DD-51, and IHLE-4040DD-51 contain the electric field associated with EMI in a tin-plated copper integrated shield, providing up to -20 dB of electric field reduction at 1 cm (above the center of the inductor) when the integrated shield is connected to ground. By eliminating the need for expensive board-level Faraday shielding to lower EMI, the devices reduce costs and save board space.
FEATURES
• High temperature, up to 155 °C
• Integrated E-Shield for maximum EMI reduction (1)
• Excellent DC/DC energy storage up to 1 MHz to 2 MHz. Filter inductor applications up the SRF (see Standard Electrical Specifications table).
• Integrated e-field shield eliminates need for separate shielding
• 20 dB e-field reduction at 1 cm – Measured vertically from top center of device
• Lowest DCR/μH, in this package size
• Handles high transient current spikes without saturation
• Coplanarity of the 4 terminals 100 μm
APPLICATIONS
• PDA / notebook / desktop / server applications
• High current POL converters
• Low profile, high current power supplies
• Battery powered devices
• DC/DC converters in distributed power systems
• DC/DC converter for Field Programmable Gate Array (FPGA)
• Telecom infrastructure Note
• Dot and shaded terminations indicate the coil pin.
Featuring high temperature operation to +155 °C and coplanarity of their four terminals within ≤ 100 µm, the inductors released today are optimized for energy storage in DC/DC converters and high current filtering. Applications include notebooks, desktop PCs, and servers; high current point-of-load converters; graphics cards; DC/DC converters for distributed power systems and FPGAs; and telecom infrastructure.
