"The frequency range of h * * * 9 / SMD crystal oscillator includes 3.072-70mhz. In SMD crystal oscillator packaging, only the frequency of h * * * 9SMD crystal oscillator can meet the low frequency below 8MHz at the same time, and the cost is low. The only disadvantage is that in the electronic world, all electronic components strive to become smaller and smaller, while h * * * 9 / SMD crystal oscillator seems to be only applied to computer motherboard, Set top box and other circuit boards without restrictions on the size of crystal oscillator. Then all this does not affect the wide application of h * * * 9 / SMD crystal oscillator!
H * * * 9 / SMD crystal oscillator length 11.0mm; 4.6mm wide; 4.2mm high. Completely sealed according to metal packaging, high reliability, automatic packaging and reflow welding.
According to the requirements of some products, the 49 / s crystal oscillator series will use insulating gaskets, because the crystal oscillator is essentially made of piezoelectric crystals, and the two surfaces of the sheet are plated with conductive materials, which should lead to wires or contacts. When working, the two surfaces always carry opposite charges respectively. If insulating gaskets are not used, the charge in the crystal oscillator is easy to be affected by the external electric field, causing the oscillation frequency to drift, or causing the crystal oscillator to stop vibration.
Although h * * * 9 / SMD crystal oscillator can meet the two advantages of low frequency and low cost at the same time, there will still be the phenomenon that the back wave of the Yangtze River pushes the front wave! Dsx320g crystal oscillator and dsx321g crystal oscillator in KDS crystal oscillator and nx3225gd crystal oscillator in NDK crystal oscillator have the lowest frequency of 8MHz. This alone has been very popular in the market. First, low-frequency crystal oscillator is used with low power consumption. Secondly, the package size of h * * * 9 / SMD crystal oscillator mentioned by Ruitai above is reduced from 11.0 * 4.6 * 4.2mm to 3.2 * 2.5 * 0.85mm, The overall size has been reduced by three times. The most important point is that the miniaturized chip crystal oscillator has more advantages than h * * * 9 / SMD crystal oscillator, falling resistance and shock resistance!
The progress of science and technology comes from the changes of these precision electronic components. When we pursue cost control, we should also consider our own needs for products. An important factor in crystal oscillator cost control is determined by the chip. The smaller the crystal oscillator size, the more accurate the chip frequency needs to be grinded, and the defect rate is very high. Therefore, the time and cost consumed in product manufacturing are also improved, so the miniaturized chip mounted crystal oscillator also reduces its space in the electric circuit. The size of h * * * 9SMD crystal oscillator is far from meeting the development of social science and technology. The above is the reference diagram of crystal oscillator size commonly used by passive chip crystal oscillator. 6035 crystal oscillator, 5032 crystal oscillator, 3225 crystal oscillator, 2520 crystal oscillator, 2016 crystal oscillator and 1612 crystal oscillator. The most commonly used chip crystal oscillator sizes are 3225 crystal oscillator and 2520 crystal oscillator. Now, in view of the rise of 2016 crystal oscillator and 1612 crystal oscillator, how can our scientific and technological products have a subversive visual experience! Wait for our future together, and what amazing technology will there be in the world!, Read the full text, technical section
