贴片电感SMD

Rated voltage 42 VAC/80 DC Rated current 200 to 1000 mA Rated inductance 5 m H to 4,7 mH Construction

■Current-compensated ring core choke with ferrite core ■Bifilar winding (B82790C0*/K0*)■Sector winding (B82790S0*/L0*)

Features

■Case flame-retardant as per UL 94 V-0■Suitable for reflow soldering

Special types for conductive adhesion

and ambient temperatures up to 150°C on request Applications

■B82790C0*/K0*:

Suppression of asymmetrical interference coupled in on lines,whereas data signals up to some MHz can pass unaffectedly ■B82790S0*/L0*:

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.Terminals

■Lead-free tinned
