Development and Evolution of 49SMD SMD Crystal

The traditional passive patch crystal oscillator is divided into two series: HC-49S/SMD (abbreviated as 49SMD) 2PAD and SMD 4PAD. Today we talk about the development and evolution of the 49SMD patch crystal for nearly two decades.

The 49SMD SMD crystal oscillator has a long history of starting mass production in China. It has been widely used in various fields since the early 1990s. Initially, on the basis of the in-line crystal oscillator HC-49S, an insulating spacer was added at the bottom to flatten the leads. Although only a small change, it met the needs of the market for component automation at the time. After several decades of technological improvement, the qualified rate of products has been continuously improved. At the same time, the degree of automation of the production line has been improved, and the production efficiency has been gradually improved. As a result, the cost of the 49SMD series products has been greatly reduced. Currently, the quartz crystal oscillator market is a highly cost-effective product.

Any product can only meet the needs of the market with continuous upgrading and improvement. 49SMD products are no exception. With the market's requirements for the miniaturization of electronic components, the thickness of the 49SMD product has been continuously improved from the earlier 4.5mm, and has successively introduced 3.0mm and 2.5mm sizes, and the volume of the product has gradually decreased.

49SMD SMD crystal oscillator product upgrade road never stops. In recent years, a variety of intelligent small home appliances in the market, digital electronic products wearable products emerged in an endless stream, the requirements for electronic components more miniaturized. Driven by this market demand, the 49SMD product has developed a smaller product - the Mini 49SMD (also known as the 49SS-7SMD series), measuring just 7x4x2mm, which is almost half of the 49SMD products of the early days.

Mini 49SMD (49SS-7SMD) products are greatly reduced in volume, compared with the same size of the traditional SMD 7050 6035 5032 series, the price has an absolute advantage, but the quality is not inferior, in recent years in the Bluetooth WiFi module It is widely used in other fields.
