chip bead array cia series- cia31 (3216 eia1206) cia series is an array of ferrite beads used for emi suppressi on filters. this series is often used for high density printed circuit bo ards to save the space and cost . it suppresses electro-magnetic wave noise by increased impedance, especially by increased resistance at noise fre quency. four lines in one chip perfect shape for automatic mounting, with no directionality. excellent solderability and high heat resistance for either flow o r reflow soldering. closed magnetic circuit configuration with no cross-talk which is sui table for high density pcbs. application emi prevention in notebook pc, lcd and car navigation ideal for dealing with line noise from multiple signals such as in computer buses specification operating temperature range C25 to +85c storage temperature range C10 to +40c product identification ci a 31 u 300 n e (1) (2) (3) (4) (5) (6) (7) (1) chip beads (2) mono-layer type (3) dimension (4) material code u: broad impedance, especially suppresses noise in the 10~200 mhz range j: suppresses noise in the 100~300 mhz range n: suppresses noise in the 200~500 mhz range (5) nominal impedance (300:30 ?, 121:120 ?)
