Frequency Response of split core current transformer

[KUMARA SHP]

I brought split core current transformer . I want to find it's datasheet or I want to get general idea about it's frequency response.
because I am going to measure current of switching mode charger , since it contains high frequency componetes I should make sure that my readings are correct .

I use following current transformers.

They use a ferrite core so should work at high frequencies.
