SAFETY REMINDERS Please pay sufficient attention to the warnings for safe designing when using this 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.) • Corrosive gases (Cl2, NH3, 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. Please use a substance such as resin that does not generate hydrogen (H2) 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. 20211202 / tpd_automotive_ntc-thermistor_ntcg_en.fm (3/17) Temperature Protection Devices Product compatible with RoHS directive Compatible with lead-free solders AEC-Q200 NTC Thermistors Automotive grade:Corresponding to 125,150°C Overview of the NTCG series CHARACTERISTICS OF NTC THERMISTORS FEATURES OF NTCG SERIES NTC(Negative Temperature Coefficient) thermistors are manufactured from sintered metal oxides. Each thermistor consists of a combination of two to four of the following materials: manganese, nickel, cobalt and copper. NTC thermistors are semiconductor resistors that exhibit decreasing resistance characteristics with increasing temperature. TDK thermistors have low thermal time constants which result in extremely high rates of resistance change to accurately track the temperature.

Thus, sufficient consideration is necessary. Set of land dimensions (1) As the stress rises in the NTC thermistor owing to the increase in silver, breakage and cracks will occur. Cause including crack, as caution on board land design, configure the shape and dimensions so that the amount of silver is appropriate. If you installed 2 or more parts in the Common Land, separated by a solder resist and special land of each component. Dimensions shape (2) When peak levels panning-at soldering is excessive, by solder contraction stress, mechanical-thermal stress causes a Yasuku chip crack. In addition, when the peak level is underestimated, terminal electrode fixed strength is insufficient. This causes chip dropouts and may affect circuit reliability. Representative example of the panning of peak levels is shown in the following. Recommended silver dose Solder stress is increased, and it is easy for a crack to form. Solder volume overload Most large serving amount Minimum prime amount Decent solder volume C B Shape symbol 0603 1005 1608 2012 A Symbol A 0.25 to 0.35 0.30 to 0.50 0.60 to 0.80 0.90 to 1.20 Fixed strength is weak, and there is connection a problem and risk of loss.
