    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.
