REMINDERS FOR USING THESE PRODUCTS
Before using these products, be sure to request the delivery specifications.
SAFETY REMINDERS
Please pay sufficient attention to the warnings for safe designing when using these products.
REMINDERS
The storage period is less than 12 months. Be sure to follow the storage conditions (Temperature: 5 to 40°C, Humidity: 10 to 75% RH
or less).
If the storage period elapses, the soldering of the terminal electrodes may deteriorate.
Do not use or store in locations where there are conditions such as gas corrosion (salt, acid, alkali, etc.).
Before soldering, be sure to preheat components.
The preheating temperature should be set so that the temperature difference between the solder temperature and chip temperature
does not exceed 150°C.
Soldering corrections after mounting should be within the range of the conditions determined in the specifications.
If overheated, a short circuit, performance deterioration, or lifespan shortening may occur.
When embedding a printed circuit board where a chip is mounted to a set, be sure that residual stress is not given to the chip due to
the overall distortion of the printed circuit board and partial distortion such as at screw tightening portions.
Self heating (temperature increase) occurs when the power is turned ON, so the tolerance should be sufficient for the set thermal
design.
Carefully lay out the coil for the circuit board design of the non-magnetic shield type.
A malfunction may occur due to magnetic interference.
Use a wrist band to discharge static electricity in your body through the grounding wire.
Do not expose the products to magnets or magnetic fields.
Do not use for a purpose outside of the contents regulated in the delivery specifications.

KMZ1608-HR type
MATERIAL CHARACTERISTIC
B material: This type is perfectly suited for fast digital signals. By equalizing R components and X components that beads possess at a
frequency of 5MHz, it is able to suppress overshooting, undershooting and ringing of fast digital signals.
R material: For wide frequency applications calling for broad impedance characteristics. For digital signal line applications calling
requiring good waveform integrity. Impedance values selected for effectiveness at 10 to 200MHz.
S material: Standard type that features impedance characteristics similar to those of a typical ferrite core. For signal line applications in
which the blocking region is near 100MHz. Impedance values selected for effectiveness at 40 to 300MHz.
Y material: High frequency range type intended for the 100MHz region and above. For signal line applications in which the signal
frequency is far from the cutoff frequency. Impedance values selected for effectiveness at 80 to 400MHz.
A material: This high-impedance product is based on the impedance frequency characteristics of our Y-material. The product offers
excellent impedance characteristics, which is greater than 2500, in the vicinity of 100MHz range (KMZ1608AHR252B).
D material: For applications calling for low insertion loss at low frequencies and sharply increasing impedance at high frequencies.
Designed for high impedance at high frequencies (300MHz to 1GHz) for signal line applications.
