feature:

1. monolithic inorganic material construction
2. closed magnetic circuit avoids crosstalk
3. smd type & suitable for reflow and wave soldering
4. available in various sizes
5. excellent solderability and heat resistance
6. high reliability
7. s/b series: effectively filtering capability over a wide range of frequency
8. h/u series: with a sharp and high frequency impedance characteristics which can effectively filter high frequency noise without attenuating high frequency signal

application:  

filtering between analog and digital circuitry, clock generation circuitry, i/o interconnects, isolation between rf noisy circuits and logic devices susceptible to functional degradation, power supply filtering to prevent conducted rf energy from corrupting the power generation circuitry, high frequency emi prevention of computer, printers, vcrs, tvs and portable telephones
