Coilcraft has introduced the SLZ family of high-current ferrite beads for power-line EMI filtering in automotive and other high-current electronic systems, including electric vehicle (EV) power electronics.
The wirewound surface-mount components are optimized for CISPR 25 EMC compliance, with EMI suppression across 30 MHz to 3 GHz. The family is designed for applications carrying approximately 5 A to more than 50 A and provides broadband impedance performance across frequency, DC current, and temperature.
In EV systems, these ferrite beads can be used to suppress high-frequency noise on power lines associated with components, such as dc-dc converters, onboard chargers, traction inverters, and battery-management electronics, where EMC performance is critical.
The SLZ family includes the SLZ4040, SLZ7030, and SLZ1380 series. Available inductance values range from 30 to 330 nH, depending on package size.
The components are AEC-Q200 qualified for automotive applications and are intended for high-frequency EMI suppression on high-current power rails.
