How to Judge the Quality when Choosing a Crystal Oscillator
As an important electronic component chip, crystal oscillators are used in many aspects. When purchasing crystal oscillators in bulk, you cannot only focus on their price, especially when comparing crystal oscillator products within your budget, you must pay attention to their quality. In order to avoid buying bad products due to pricing, let me tell you the common methods to judge the quality of crystal oscillators, so that you can use them as a reference when choosing such products.
1. Judge the quality of crystal oscillators through appearance details
When we judge the quality of crystal oscillator products, we can first judge from the appearance details. After getting the sample of the crystal oscillator product, check the workmanship of the shell base and leads, especially the brightness, whether there are unclear or fuzzy pin positions, and whether the overall appearance is clean and dust-proof. When we unpack the crystal oscillator, we often ignore fingerprints or dust, and whether the gap between the casing and the base meets normal standards are all details that can judge the quality of the crystal oscillator. If the crystal oscillator is found to have obvious yellowing, oxidation marks or low gloss, then the quality of the crystal oscillator is often not high.
2. Use anti-counterfeiting marks to ensure that the crystal oscillator is authentic
It is precisely because for electronic products such as crystal oscillators, there are many brands and uneven quality, so more attention must be paid to whether they are genuine or not to ensure that the products work properly during use. When purchasing, in addition to judging the quality of the crystal oscillator by its appearance, you must also ensure that it is genuine and not imitations. Genuine crystal oscillators all have laser-engraved anti-counterfeiting marks, which is what we usually call silk screen. At the same time, different brands of anti-counterfeiting marks have different formats and contents. This requires checking the anti-counterfeiting methods of the specific brand, and the packaging aspect often also needs to be considered. Authentic products The crystal oscillator package is introduced in great detail, from QC inspection and confirmation to resistance value and accuracy requirements and production date.
3. Pay attention to crystal oscillator procurement channels and brand reputation
In order to ensure that the crystal oscillator products purchased are of high quality, it is natural to pay attention to the brand and purchasing channels. After deciding which brand of crystal oscillator to buy, you must pay attention to the purchasing channel. If you are buying at a flagship store or official website, you must ensure that the certification mark and official website domain name registration information match the brand. If you are buying on a platform, you must also understand the platform itself. The certification system, platform and merchants provide what kind of warranty, etc. These are all ways to ensure that the purchased crystal oscillator products are genuine and good.
In fact, with the diversification of purchasing channels for crystal oscillator products and the emergence of various brands, you can also learn more about the reputation of the brand when purchasing crystal oscillators, and you can also test samples to confirm that the crystal oscillator you purchase is a good product. At the same time, you cannot ignore the behind-the-scenes of the product when purchasing. The guarantee and service provided by merchants are also key factors in ensuring the quality of crystal oscillator products and purchasing experience.

Crystal Oscillator PPM Error Analysis and Calculation Method
Crystal oscillator accuracy is usually measured in PPM, which describes the frequency stability or deviation of the crystal oscillator. PPM represents the relative error between the actual output frequency and the nominal frequency, and is an important parameter for measuring the frequency accuracy of the crystal oscillator.
