New compact SMT chokes for low-voltage applications

29 June 2022 Passive Components

TDK Corporation has released three new B8272* series of compact EPCOS SMT common-mode chokes specially developed for low-voltage applications.

The chokes can sustain voltages of up to 48 V AC (50/60 Hz) and 80 V DC, and continuous currents between 1,8 and 19 A at an ambient temperature of 40°C. The new series cover a range of inductance values from 0,59 to 5,6 mH.

These new EMC components have very compact dimensions with a surface area of between 12,7 x 12,7 mm and 30,99 x 25,4 mm, and a height of 5,46 to 12,7 mm. The design and materials of the RoHS-compatible components comply with UL 94 V-0 and offer a relatively high leakage inductance of up to 1,2% of the nominal inductance, which reliably suppresses common-mode interference.

Areas of application for the new common-mode chokes include DC/DC converters and other low-voltage applications.
