The electrical characteristics of the LXES1UTAA1-157 and LXES1UTBB1-157 are identical. The number of windings differs, so please refer to the datasheet for details.
Along with the miniaturization of mobile devices, the size requirements placed on TVS Diodes are also becoming increasingly severe.
Murata makes use of its technology fostered through the development of laminated ceramic capacitors and inductors, and also develops small TVS Diodes.
