PCN Notifications

Product changes allow Bel to improve quality, performance and manufacturing efficiency. As part of our product change process, Bel Fuse commits to notification of any change that may affect fit, form, or function of the device. This determination is made by Bel Fuse and is based on data available at the time of the PCN release. This notice will typically be given 3 months in advance of the change.
