E-M-I: three dreaded letters for any designer. And while I can’t solve all your EMI problems, the Vishay IHLE power inductors can certainly help. IHLE is based on the same technology used in IHLP inductors, which suppresses radiated magnetic fields, or B-fields, and conducted EMI. But IHLE inductors add an integrated shield to contain E-fields as well, reducing the E-field by up to 20 dB at 1 cm. This lets you ditch the external shielding for a more compact, lower-cost design. IHLE inductors are AEC-Q200 qualified, can operate at temperatures up to 155°C, and can handle high transient current spikes without saturation, so they’re the perfect match for automotive ECUs, DC/DC converters, and motor noise suppression. The inductors are available with inductance values from 0.22 µH to 68 µH and in case sizes from 2525 to 4040. They offer the lowest DCR/µH available for each case size. 2020 and 5050 sizes are coming soon.
