Specifications subject to change without notice. Note 1: For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: support@synqor.com) Note 2: There is no derating with a baseplate temperature of 100ºC or lower. Note 3: Higher values of isolation capacitance can be added external to the module. |
