Group, The storage temperature of most ferrite chip beads (certainly all the datasheets I have looked at) specify an operating temperature range that is much wider than the storage temperature range. Typically these are -55 to +125°C operating and -20 to +40°C storage.
Q1: Why is this so? Q2: If I use ferrites in a PCB, is my storage temperature for the whole product restricted by the storage temperature of the ferrites? Thanx in advance.
