New chip varistor series for automotive applications
The requirements on product reliability in the automotive sector are
among the toughest in industry. Targeting these demands KOA introduced
the chip Varistor series NV73DL for automotive applications. The
complete AEC-Q200 test data is available now for the new Varistor
series.
The NV72DL Varistor is ideal suited for counter measures against ESD
voltages. Its symmetrically non linearity V-I characteristic absorbs
positive and negative surges. The NV73DL offers high maximum energy of
up to 1.5 Joule in a 1206 package. Its low leakage current contributes
to the efficiency of the whole system. High reliability is
achieved by excellent resistance to cycling temperature stress. All
these values combined make the NV73DL series ideal for absorption of
surge voltages in automotive, occurring from inductive loads, motors
and relays etc. They are also suited for protecting semiconductor
elements against over voltage.
Three different Varistor chip sizes are available: 0603, 0805 and 1206
(inch). The Varistor voltage range covers 10V up to 90V. Operation of
the NV73DL is possible between -40°C and +125°C.
