On-Line Input Resistors Slide 7

Shown here is a summary of the portfolio, indicating the main features of each product. Apart from the high surge film part, EMC, all these products use wirewound technology. Most have ceramic cores but SPP has a fibreglass core which encourage faster fusing at lower overload fault conditions. All these parts have a good ability to withstand surges, but some, like WHS are designed to excel in this regard. All these parts can safely fuse at line voltages, and all four have UL recognition. Finally, although these are axial through-hole components, several are optionally available with Z-form leads for pick & place and reflow processing.
