The contactor, based on Multitest’s Cantilever technology, is used in MOSFET, drivers, IGBT, power modules, and power package (TO, SO and DIP) testing. It has low, stable contacting resistance to achieve equal current symmetry over I/Os within the contactor. Maximum inductance is 4.5nH for 0.5mm pitch. Resistance stability is influenced by the contact spring and the condition of the device pin.
It can be used for temperatures from -60 to +175°C is required, meeting automotive application requirements. Thermal management within the contactor supports temperature stability during test.
The ecoAmp offers a lifespan of 1 million insertions.
