B82559A*A033 Series ERU33 Chokes

EPCOS - TDK Electronics' B82559A*A033 series shielded ERU33 high-current chokes for through-hole mounting are designed for very high saturation currents from 32 A to 83 A at ±100°C and offer six types which cover a range of inductance values from 3.2 µH to 10 µH. DC resistances are as low as 0.85 mΩ or 1.2 mΩ, depending on the type. Thanks to the flat-wire winding, the chokes have very compact dimensions of only 33 mm x 33 mm x 15 mm. By thermally connecting the flat-wire winding to the core, the large ferrite surface can be coupled to a heat sink for effective heat dissipation. In addition to the standard types, customized variants with other inductance values can also be realized.

The RoHS-compatible and AEC-Q200 REV D-qualified inductors are designed for operating temperatures from -40°C to +150°C. Typical automotive applications are buck-boost chokes for DC/DC converters, such as for 48 V onboard power supplies or differential mode chokes in the input filter of onboard chargers. In industrial electronics, they can be used as storage and output chokes in high-current supplies and PoL supplies.
