    Mechanical Requirements


    ItemRequirementsTest Method
    1.Solder-abilityThe terminals shall be uniformly tinned, and its area≥95%Dipping theNTC terminals to a depth of 15mm in a soldering bath of 245±5℃ and to the place of 6mm far from NTC body for 3±0.5s (See IEC68-2-20 /GB2423.28 Ta )
    2.Resistance To Soldering Heat

    No visible mechanical damage.

    ΔR/RN ≤20%

    (ΔR =∣RN-RN'∣)

    Dipping the NTC terminals to a depth of 15mm in a soldering bath of 260±5℃ and to the place for 6mm below from NTC body for 3±0.5s.After recovering4-5h under 25±2℃. The rated zero power resistance value RN' shall be measured.

    (See IEC68-2-20 /GB2423.28 Tb)

    3.Strength of lead terminal

    No break out

    ΔR/RN ≤20%

    (ΔR =∣RN-RN'∣)

    Fasten the body and apply a force gradually to each lead until 10N and then keep for 10sec, Hold body and apply a force to each lead until  90°slowly at 5N in the direction of lead axis and then keep for 10sec, and do this in the opposite direction repeat for other terminal. After recovering 4~5h under 25±2℃, the rated zero power resistance value RN' shall be measured.

    (See IEC68-2-21/GB2423.29 Ua / Ub)
