Second: features: 1: mf5b series of products for the co-directional thin-film package type 2: insulation film packaging, thermal induction speed, high sensitivity 3: good stability and high reliability 4: good insulation 5: high precision resistance 6: small size, light weight, rugged, easy to install automatically Three: product model description Mf 5b 103 f 3950 1 2 3 4 5 1, mf ⬠- negative temperature coefficient (ntc) thermistor code. 2, 5b - thin film thermistor. 3, 103 - thermistor nominal resistance, said the resistance of the nominal resistance: 10 103 F, 1%, g, 2%, h, 3%, j, 5% of the resistance value (accuracy) 4, 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
