Remark:*The first pane fills with code of different diamension,The second pane fills with Rated Resistance,the third fills with its precision symbol.
*B value(25/50¡æ) error:the corresponding error is ¡À1% for which the precision of the rated resistance is ¡À1%,others is ¡À2%.
*Besides,our corporation can supply products according to the demands of users.
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.
*While,please soldering at the distance of 5mm from the bottom of wire at least. |
