The frequency range of the H***9/SMD crystal oscillator includes 3.072-70MHZ. In the SMD crystal oscillator package, only the frequency of the H***9SMD crystal oscillator can satisfy the low frequency below 8MHZ, and the cost is low. The only drawback is that In the electronic world, all electronic components are trying to become more and more miniaturized, and the H***9/SMD crystal oscillator seems to be used only in computer boards, set-top boxes and other boards that have no limitation on the crystal size. Then all this does not affect the wide application of H***9/SMD crystal oscillator!
H***9/SMD crystal length 11.0mm; width 4.6mm; height 4.2mm. Completely sealed according to metal packaging, high reliability, automatic packaging, reflow soldering.
According to some product requirements, 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-like conductive material should be wire or joint. When working, the two surfaces always carry opposite charges. If the insulating spacer is not used, the charge in the crystal is easily affected by the external electric field to cause the oscillation frequency to drift, or the phenomenon that the crystal oscillator stops vibrating.
Although the H***9/SMD crystal oscillator can satisfy both the low frequency and the low cost, there will still be a phenomenon in which the waves of the Yangtze River push forward waves! The DSX320G crystal oscillator and the DSX321G crystal oscillator in the KDS crystal oscillator, the NX3225GD crystal oscillator frequency in the NDK crystal oscillator can be as low as 8MHZ. In this case, it has been very popular in the market. First, the first use of the low-frequency crystal oscillator, the power consumption is small. Secondly, in the above-mentioned H***9/SMD crystal oscillator mentioned by Ruitai, the package size is reduced from 11.0*4.6*4.2mm to 3.2*2.5*0.85mm, and the overall size is reduced by three times. The most important point is that the miniaturized patch crystal oscillator has better performance than the H***9/SMD crystal oscillator, resisting falling and shockproof!
The advancement of technology comes from the changes in these precision electronic components. When pursuing cost control, we must also consider our own needs for products. An important factor in crystal cost control is determined by the chip. The smaller the crystal oscillator size, the more accurate the chip frequency needs to be ground, and the defect rate is very high. Therefore, the time and cost consumed in product production are also improved. The patched crystal oscillator also reduces its space in the circuit. The size of the H***9SMD crystal oscillator is far from meeting the development of today's social technology. The above is the crystal size reference diagram commonly used for passive patch crystals. 6035 crystal oscillator, 5032 crystal oscillator, 3225 crystal oscillator, 2520 crystal oscillator, 2016 crystal oscillator, the most commonly used patch crystal size of 1612 crystal oscillator is 3225 crystal oscillator and 2520 crystal oscillator. Now for the rise of the 2016 crystal and the 1612 crystal, our technology products will have a subversive visual experience! Waiting for our future world together, there will be some amazing technology!
