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

Please pay careful attention to the precautions and follow safe designing practices when using these products.

Incorrect usage may lead to destroyed NTC thermistors and damages or malfunctions with the devices used.

Please use them within the ranges of the ratings and performance provided in the Catalog and delivery specifications upon confirming the

environments where they are to be used and installed.

Do not use them outside the operating temperature range.

Do not use them with the ratings or maximum permissible power levels exceeded.

Do not quickly apply 5mW or more of load with the constant-voltage power supply in the NTC thermistor as this may lead to staying in

thermal runaway mode or the red-shorting of chips.

Please be cautious of the applied voltage in thermistors as instruments may malfunction with the lowering of resistance due to self heating.

With instruments that consumers can touch the thermistors with their hands, please carefully warn them not to touch the thermistors.

Store them in locations where the temperature is –10°C to +40°C and the relative humidity is 75% or below, avoid environments where

there are sudden changes in temperatures, direct sunlight, corrosive gas, grit, or dust, and keep them packed in a manner where no

loading stress is applied in order to avoid deterioration and damage. (Please use them within six months.)

When sealing thermistors, please do so upon first considering the type, quantity, hardening conditions, and adhesiveness of the sealing

material and confirming its reliability.

Avoid powerful vibrations, impact (such as by dropping), pressure, etc. on thermistors that exceed the prescribed levels.

Do not use them for long periods of time in environments with a relative humidity of over 85%. (This excludes cases where

countermeasures have been taken.)

Do not use them in the following environments. (This excludes cases where countermeasures have been taken.)

・Environments

with corrosive gas (Cl

, NH

, SOx, NOx, etc.)

・Environments

with highly conductive substances (electrolytes, water, saltwater, etc.)

・Environments

with acid, alkali, or organic solvents

・Dusty

areas

Please observe the following precautions when attaching them to substrates as failure to do so may result in destruction or malfunction.

・Do

not let the substrates get warped or twisted at any time during the soldering.

・The

landing size must be even on both the left and right sides.

・Do

not use items that have been dropped or detached.

・Do

not allow the adherence of more solder than needed.

Reflow mounting is recommended with NTC thermistors, and not flow (dip) mounting.

Attaching or making corrections with a soldering iron is not recommended as it can lead to troubles such as significant distorting due to

thermal shock or cracking. If a soldering iron must be used, it should be 30W or below with the temperature of the tip at 350°C or below,

and at a maximum of 5 seconds of soldering time. Also, do not let the tip of the soldering iron come in direct contact with the chips.

When attaching or making corrections with a soldering iron, the temperature of the tip of the soldering iron should be 350°C or below at a

maximum of 5 seconds of soldering time. Do not let the tip of the soldering iron come in directly come in contact with the chips as doing

so may lead to particularly large distortions due to thermal shock or cracking.

Please use a substance such as resin that does not generate hydrogen (H

) when forming insulation film over chips.

Please contact our sales offices when considering the use of the products listed on this catalog for applications, whose performance and/

or quality require a more stringent level of safety or reliability, or whose failure, malfunction or trouble could cause serious damage to

society, person or property ('specific uses' such as automobiles, airplanes,medical instruments, nuclear devices, etc.) as well as when

considering the use for applications that exceed the range and conditions of this catalog.

Please note that we are not responsible for any damages or losses incurred resulting from the use of these products that exceeds the range

and conditions of this catalog or specific uses.

Please take appropriate measures such as acquiring protective circuits and devices that meet the uses, applications, and conditions of the

instruments and keeping backup circuits.
