SMD CHOKE COILS
SERIES SM
FEATURES
High current capacity at RF frequency
Better performance when using it as choke coil at high frequency and with DC/DC converter.
Low voltage drop. Excellent stable inductance value with temperature rise and current applied.
Miniature wire wound, open magnetic path construction inductor with low DCR.
Low price

Please do not use cleaning solvent or any type of cleaning chemical to
clean these items. Also temperature must be within maximum of 40
°
C.
If put on board that requires resin coating later, please note that L
may change due to relatively high resin curing stress, so please select
type of resin carefully.
Product must be used within 12 months from Production date on
reel or on our invoice. Check solderability after 12 months.
Must be stored in controlled humidity, and on tape and reel.
