Currently available in SMD format and packaged in stackable trays or tape and reel packaging. The product range has been recognized by the Underwriters Laboratory (UL) to UL60950, file number E79522 applies.

If components are required in tape and reel format suffix order code with -R, e.g. NNL05-9C-R. 2. A 330F low ESR capacitor, approx 7m at 00kHz to 300kHz must be fitted at the input to the NNL DC/DC converter to ensure stability under all the operating conditions. All specifications typical at TA =25C, nominal input voltage and rated output current unless otherwise specified.
