Technical Application Notes For Inductors And Chokes
Selecting The Optimum Indcutor Choke to Best Match The Right Performance
Inductive components store energy intermittently in switch-mode power supplies and DC/DC
converters, form parts of RF circuits or RFID systems, transform current/voltage, match
impedances, are filter elements and last but not least interference suppression components to
ensure EMC.
The requirements on inductors depend on how and where they are used. RF circuits need coils with
high quality factors and resonant frequencies. EMC applications require high inductance to achieve
good interference suppression characteristics, low Q factors being more desirable here due to the
need to avoid resonance.
Token Electronics provides suitable inductive components for all applications. This quide contains
a wide selection of standard components, from SMT types through high current inductors for power
electronics applications to transformers.
