INDUCTIVE COMPONENTS Last Time Buy - JW Miller® Models PM63S and PM105S Riverside, California - July 1, 2008 - JW Miller® Models PM63S and PM105S were discontinued by JW Miller before they were acquired by Bourns in April 2006. We have been supplying small quantity, infrequent orders for these models as a courtesy. We shall no longer be accepting orders for these models as of August 1, 2008. Model PM63S had no JW Miller® replacement. The nearest equivalent is the Bourns® Model SRR4028, which is electrically equivalent, but not physically identical. JW Miller recommended Model PM105SB as the replacement for Model PM105S. Model PM105SB is still offered by Bourns as a standard product. The data sheets for Models PM63S and PM105S are available for reference on pages 2 and 3 of this announcement. Data sheets for Models SRR4028 and PM105SB are available on Bourns website. They may also be accessed directly from the links below.
