3.5 Headphone socket inspection control
The workshop set the general policy check method; reflection and month summary. Found that the increase or decrease in the rate of missed inspections must be summed up in 1 policy management: setting a missed inspection policy for inspection posts.
The leader of the team inspects and samples the internal DC power socket 2 during the inspection process.
At the time of on-site correction and teaching, the inspection results of the inspection positions shall be sampled.
After passing the examination and issuing a job permit 3, the examiner will conduct a vibration switch once a year to check the standardized training.
The first and second digits are valid values. 3.5 Earphone Jack Digital Law: A symbolic method of using a three-digit number to indicate the nominal value on a resistor. Digital from left to right. The third place is the index, that is, the unit of zero is Europe.
With a variety of utility selection, device form has DIP and SMT for selection. Elastic structure planning is used for touch terminals. Expertise: It has a 5.1 channel audio high-fidelity structure plan. Ensure a good and smooth touch of each application life.
Headphone socket uses: used in mobile phone stereo planning, CD players, wireless phones, MP3 players, learning machines, DVD digital cameras and other digital voice information terminals.
Not much current intensity. Because of the different thickness of wire, the acceptable current intensity is not the same as the specification: welding temperature 260±5°C 10S, insertion force 3~20N, life 5,000 times 3.5 Earphone Socket What is the acceptable current density?
Such as: L6 marked number 6 inductance. Inductor coils are made by winding an insulated wire around a certain number of turns on an insulating skeleton. DC through the coil, 3.5 headphone jack in the circuit commonly used "L plus digital shows. DC resistance is the resistance of the wire itself, the pressure drop is very small;
