Three: product model description
MF 5B 103 F 3950
① ② ③ ④ ⑤
①MF ¬ - negative temperature coefficient (NTC) thermistor code.
② 5B - thin film thermistor.
③103 - thermistor nominal resistance, said the resistance of the nominal resistance: 10 × 103 (Ω).
F = ± 1%, G = ± 2%, H = ± 3%, J = ± 5% of the resistance value (accuracy)
⑤ 3950 - resistance of the thermal index (material coefficient) B value: 395 × 10 (K)
F = ± 1%, G = ± 2%, H = ± 3%, J = ± 5% of the resistance value (accuracy)
⑤ 3950 - resistance of the thermal index (material coefficient) B value: 395 × 10 (K)
MF5B series of products using Note:
1: Do not arbitrarily bend resistance wire frame, So as to avoid chip and cable off, Causing poor resistance
2: welding temperature should not exceed 300 ℃, Welding time is best not more than 0.5 seconds
3: thermal casing using hot air gun, Air gun temperature should be controlled at about 120 ℃
4: When welding using a constant temperature soldering iron, Tip flat, One hand to get resistance, One hand to wire touch welding, Can improve production efficiency and shorten the welding time
5: Special Note: Do not touch the chip hand (that is, resistive top)
