The N-ZP,N-ZEP,N-ZPS,N-ZL,N-Z,N-ZA,N-ZE series are called Chip Beads and used for EMI suppression.The chip beads suppress noise by impedance while increases along with frequencies. Especially at high frequencies, the chip beads can reduce high frequency noise elements without affecting transmission signals by an increase of resistance elements due to high frequency loss of chip beads.

■Outline of chip beads for signal line
Chip Beads for electric current line are the Rdc product that considerably increase the allowable electric current while keeping a function of reducing noise, and make countermeasures for noise possible in electric power source line such as IC.
As a characteristics of impedance, they can effectively reduce/prevent the transmission of noises from electric power source line and leaks to its power source line when mounted in tandem in the line. The product has two types of N-ZP(~2.5A) / N-ZEP(~3.5A) and N-ZPS(~6A) according to the capacity of electric power source line.

■Outline of chip beads for signal line
Chip Beads are surface-mount devices that boast wide impedance characteristics usually obtained by a range of chip beads from chip beads to troidal chips. Having a totally monolithic structure, they can reduce noise in the equipment when mounted in series in its noise inducing area. To meet requirements in various situations, these chip beads use four different resistance elements(R),and come in sizes from 1608 to 3216.

■Features of each series

•	N-ZL series N-ZL series has the impedance characteristic that is high Q by extremely keeping a crossing of a reactance elements(X) and a resistance elements(R) a high frequency. It is suitable for noise control of frequency band area of 200MHz - 500MHz.
•	N-Z series N-Z series has high impedance at a comparatively wide frequency band level. It is suitable for noise control of frequency band area of 100MHz - 300MHz.
•	N-ZA series N-ZA series suppresses a reactance elements(X) and restrains a distortion of a signal wave pattern. It prevents a quality fall of a digital signal wave pattern and controls a high frequency noise.
•	N-ZE series N-ZE series extremely suppresses a reactance elements(X) and controls a crossing of R and X in less than 10MHz. It reduces noise elements of a wave pattern by converting them into heat with pure resistance elements of impedance.
