s
High performance
Case flame-retardant as per UL 94 V-0
Suitable for reflow soldering and conductive adhesion
Operation up to 150˚C
Applications
s
B82799-C:
Suppression of asymmetrical interference coupled in on lines,
whereas data signals up to some MHz can pass unaffectedly
s
B82799-S:
Suppression of asymmetrical and symmetrical interference
coupled in on lines. The high-frequency portions of the symmetrical
data signal are decreased so far that EMC problems can be
significantly reduced
Marking
Manufacturer, inductance value (coded),
date of manufacture, coded (year, day of week, calender week)
Delivery mode
Blister tape, reel packing
