Vishay IHLE® Series
Vishay Intertechnology expands its IHLE® series of low profile, high current inductors featuring integrated E-field shields with a new second-generation Automotive Grade device in the 10 mm by 10 mm 4040 case size. Offering an improved shield design over previous-generation solutions, and polarity marked for more consistent EMI performance, the Vishay Dale IHLE-4040DDEW-5A lowers costs and saves board space by potentially eliminating the need for separate board-level Faraday shielding.
- Compared to traditional composite inductors, the IHLE-4040DDEW-5A contains the electric and magnetic fields associated with EMI in a tin-plated copper integrated shield
- When the shield is connected to ground, the device provides up to 20 dB reduction in radiated noise interference, and a further 6 dB reduction in magnetic flux leakage to minimize crosstalk to nearby board components
- Packaged in a 100 % lead (Pb)-free, magnetically shielded, iron alloy encapsulant
- The IHLE-4040DDEW-5A offers high resistance to thermal shock, moisture, and mechanical shock from the additional mounting support provided by its two shield terminals
