Note 1. The NTE3029A is a discontinued device and has been replaced by NTE3029B.
Note 2 Measured with device soldered into a typical printed circuit board.
Note 3 Maximum exposure time: 5sec. Minimum of 1/16 inch from the case. A heat sink should
be applied in order to prevent the case temperature from exceeding +100°C.
