■ PRECAUTIONS
＊This catalog contains the typical specication only due to the limitation of space. When you consider purchase of our products, please check our specication.
For details of each product (characteristics graph, reliability information, precautions for use, and so on), see our Web site (http://www.ty-top.com/) or CD catalogs.
Precautions on the use of Multilayer chip Inductors, Multilayer chip inductors for high frequency, Multilayer ferrite chip beads
1. Circuit Design
Precautions
◆Verication of operating environment, electrical rating and performance
1. A malfunction in medical equipment, spacecraft, nuclear reactors, etc. may cause serious harm to human life or have severe social ramications.
As such, any inductors to be used in such equipment may require higher safety and/or reliability considerations and should be clearly differentiated from
components used in general purpose applications.
◆Operating Current（Verication of Rated current）
1. The operating current for inductors must always be lower than their rated values.
2. Do not apply current in excess of the rated value because the inductance may be reduced due to the magnetic saturation effect.
2. PCB Design
Precautions
◆Pattern congurations（Design of Land-patterns）
1. When inductors are mounted on a PCB, the size of land patterns and the amount of solder used（size of llet）can directly affect inductor performance.
Therefore, the following items must be carefully considered in the design of solder land patterns:
（1）The amount of solder applied can affect the ability of chips to withstand mechanical stresses which may lead to breaking or cracking. Therefore, when
designing land-patterns it is necessary to consider the appropriate size and conguration of the solder pads which in turn determines the amount of
solder necessary to form the llets.
（2）When more than one part is jointly soldered onto the same land or pad, the pad must be designed so that each component's soldering point is separated
by solder-resist.
（3）The larger size of land patterns and amount of solder, the smaller Q value after mounting on PCB. It makes higher the Q value to design land patterns
smaller than terminal electrode of chips.
◆Pattern congurations（Inductor layout on panelized［breakaway］PC boards）
1. After inductors have been mounted on the boards, chips can be subjected to mechanical stresses in subsequent manufacturing processes（PCB cutting,
board inspection, mounting of additional parts, assembly into the chassis, wave soldering the reow soldered boards etc.）For this reason, planning pattern
congurations and the position of SMD inductors should be carefully performed to minimize stress.

◆Pattern congurations（Design of Land-patterns）
1. The following diagrams and tables show some examples of recommended patterns to prevent excessive solder amounts（larger llets which extend above
the component end terminations）.Examples of improper pattern designs are also shown.
