PRECAUTIONS
1. Circuit Design
Precautions
◆Operating environment
1. The products described in this specification are intended for use in general electronic equipment,(office supply equipment,
telecommunications systems, measuring equipment, and household equipment). They are not intended for use in mission-critical
equipment or systems requiring special quality and high reliability (traffic systems, safety equipment, aerospace systems, nuclear
control systems and medical equipment including life-support systems,) where product failure might result in loss of life, injury or
damage. For such uses, contact TAIYO YUDEN Sales Department in advance.
2. PCB Design
Precautions
◆Land pattern design
1. Please refer to a recommended land pattern.
2. There is stress, which has been caused by distortion of a PCB, to the inductor.
(NR30/40/50/60/80, NRV20/30, NRH24/30, NRS20/30/40/50/60/80 Type)
3. Please consider the arrangement of parts on a PCB. (NR30/40/50/60/80, NRV20/30, NRH24/30, NRS20/30/40/50/60/80 Type)
Technical
considerations
◆Land pattern design
Surface Mounting
1. Mounting and soldering conditions should be checked beforehand.
2. Applicable soldering process to this products is reflow soldering only.
3. Please use the recommended land pattern shown as below. Electrical characteristics and the mounting ability of the product are being
considered in the recommended land pattern. If a PCB is designed with other dimensions, defective soldering and stress to a product
may occur due to misalignment. The performance of the product may not be brought out. If an adopted land pattern is different from the
recommended land pattern, stress to the product will increase. It may cause cracks or defective electrical characteristics of the
product. Please conduct validation completely before studying adoption of this product and please judge the pros and cons of adoption
of this product with taking on responsibility.
(NR30/40/50/60/80, NRV20/30, NRH24/30, NRS20/30/40/50/60/80 Type)
4. As coefficients of thermal expansion between an inductor and a PCB differs, cracks may occur on a ferrite core when thermal stress is
applied to them after mounting an inductor. (Please refer to the drawings below.) Please conduct validation completely before studying
adoption of this product and please judge the pros and cons of adoption of this product with taking on responsibility.
(NR30/40/50/60/80, NRV20/30, NRH24/30, NRS20/30/40/50/60/80 Type)
5. SMD inductors should be located to minimize any possible mechanical stresses from board warp or deflection. When splitting the PC
board after mounting inductors and other components, care is required so as not to give any stresses of deflection or twisting to the
board.

7. Storage conditions
Precautions
◆Storage
1. To maintain the solderability of terminal electrodes and to keep the packing material in good condition, temperature and humidity in the
storage area should be controlled.
Recommended conditions
Ambient temperature : -5~40℃
Humidity : Below 70% RH
The ambient temperature must be kept below 30℃. Even under ideal storage conditions, solderability of products electrodes may
decrease as time passes.
For this reason, product should be used within 6 months from the time of delivery.
In case of storage over 6 months, solderability shall be checked before actual usage.
Technical
considerations
◆Storage
1. Under a high temperature and humidity environment, problems such as reduced solderability caused by oxidation of terminal electrodes
and deterioration of taping/packaging materials may take place.
