Sample kit offered for series of compact high-current chokes

TDK Corporation offers a sample kit for the B82559A*A033 series of shielded EPCOS ERU 33 high-current chokes. The sample kit (ordering number: B82559X033) comprises two pieces of each of the six standard types of this series. As well as the standard types in the sample kit, customised versions of the chokes with other inductance values can also be realised.

Designed for very high saturation currents from 32A to 83A at +100C, these through-hole mountable components cover a range of inductance values from 3.2µH to 10µH. DC resistances are as low as 0.85mOhm or 1.2mOhm, depending on the type. Thanks to the flat wire winding, the components have very compact dimensions of only 33mm x 33mm x 15mm. By thermally connecting the flat coils to the electrically insulated core, the choke can be connected to a heat sink to dissipate the heat effectively.

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