!Note
NFA31C series is a chip EMI suppression filter for
surface mount applications using Murata's ceramic
processing technology and filter design technology.
The series is well suited for EMI suppression in
digital I/O lines of varied electronic equipment such
as notebook size PCs.
1. High density mounting can be realized because of 4
2. Suitable for high frequency noise suppression
3. Excellent EMI suppression can be realized because
4. 22 to 22,000pF lineups can be used depending on
1. Personal computers and peripherals
2. Telephones, PPCs, communications equipment
3. Digital TVs, DVDs
