Remark:
* B Value (25/50C) error is ±1% for components with rated resistance tolerance of ±1% and ±2% for all others.
Notice:* The two ends of the lead wire cannot endure too big pull because of the small size and soldered spot in series of MF52.* Solder at least 5mm from the bottom of wire.

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.
