8. Precautions in use
8-1 Storage
(1) The product shall be stored in a room temperature and humidity must be controlled.
( temperature 5 to 35℃, humidity 45 to 85%RH )
(2) The product shall be stored as direct sunshine doesn’t hit on it.
(3) The product shall be stored with no moisture, dust, a material that will make Solder ability inferior,
and a harmful gas (hydrogen chloride, sulfurous acid gas, and hydrogen sulfide).
(4) Resistor shall be stored with keeping the minimum package unit with uncivilized sealed ( Keep the
state of the taping).
8-2 Time limit to storage
(1) The storage time limit of the product is reckoned on the day when product was shipped by our
company and made within one year.
(2) Confirm solder ability beforehand when you use the one that the time limit was passed.
8-3 Chip mounting
(1) When chip are mounted on the PC board, the protective coat of the product must not be scratched. If
it will be scratched, it will make characteristic inferior.
(2) In case that product will be soldered by soldering iron, heating shall be done on the land, and
soldering iron must not hit in the product itself.
(3) In case that resin coating or resin seal will be made for a PC board after chip mounting, do washing
and drying it enough before coating or sealing. If ion bear or moisture will be sealed in resin coating,
it will make characteristic inferior.
For resinous use, it is necessary to set up enough the curing conditions. As it gets improper for the
condition, changes of a resistance value are large and are a case.
(4) According to shape, material, and pressure of clamping in chip mounting machine, there is the case
that crack will be appeared on the product.
Control a shock energy for clamping the product under 7 × 10-4 J
With a shock energy around clamping that says here, it is suited to a potential energy, in case that iron
block of 25g is dropped naturally to the product placed on iron plate for the height of 2.8mm.
(5) The glue to fix the product on the PC board around chip mounting, it is needed high insulation
resistance and great performance or moisture. And it is needed that these characteristic are not inferior
in using temperature range and a hot spot temperature to be acting.

8-4.Using and Handling
(1) Use under the special environment
Performance and reliability are fully researched in advance, and it must be confirmed when a use part
under the special environment is used with the special environment .There is the following thing in the
special environment.
﹝1﹞Water, salt water, oil, the inside of acid, alkali, the liquid such as an organic solvent or the place
where it reaches it
﹝2﹞The place where direct sunlight hits it, an exposure in the open air, the inside of the dust
﹝3﹞The condensation
﹝4﹞The place where harmful gas(in such cases as the sea breeze,HCl,Cl2,SO2,NH3,NOX) is abundant.
Water or ion quality sometimes reaches even a body and an electrode by the protection material of
the resistor being eroded gradually under the above environment. Then investigation confirmation
is necessary because resistance value may change due to the chemical reaction such as electrolysis.
(2) Use under the high temperature environment
When components are used under the high temperature environment, load electric power must be
reduced based on the reduction curve prescribed in every kind.
(3) Investigate the performance and reliability enough when using under harsh environment.
(4) Protect the edge and protection coat of resistors from mechanical stress.
(5) Handle with care when PC board is divided or fixed on support body, because bending of PC board after
chip mounting will make mechanical stress for resistors.
(6) Resistors shall be used with in rated range shown in specification.
Especially. If voltage more than specified value will be loaded to resistor, there is a case it will make
damage for machine because of temperature rise depending on generation of heat, and increase value or
breaks.
(7) In case that resistors is loaded voltage, it is necessary to confirm temperature of resistor and to reduce a
load power according to load reduction curve, because a temperature rise of a resistor depends on
influence of heat from mounting density and neighboring element.
(8) Observe Limiting element voltage and maximum overload voltage specified in each specification.
(9) If there is a possibility that a large voltage (pulse voltage, shock voltage) charge to resistor, If is
necessary that operating condition shall be set up before use, because performance of thin film resistor is
affected by a large shock voltage.
