The crystal oscillator purchasing process can be a headache if you don't know what to expect. However, learning the basics of procuring frequency control devices can help you to plan accordingly and decrease your frustration. We'll keep this one short and to the point.
There are 3 main things you should know when procuring crystal oscillators & timing devices
- Long lead times
- Long shelf life
- Large purchased lot sizes
Let's dive a little deeper into each of these to give you a better idea of how they'll impact your frequency control & oscillator purchasing strategy.
3 Things to Know When Procuring Crystal Oscillators & Frequency Control Devices
1. Long Lead Times
You should expect long lead times when it comes to frequency control devices. Especially with custom orders. This is typically due to aging as it takes a lot of time to perfect. The same goes for exacting the frequency.
A common lead time in the frequency control industry is anywhere between 8-12 weeks. However, it can also be longer or shorter. Be sure to contact the manufacturer or supplier well in advance to get an idea of what you can expect.
2. Long Shelf Life
The typical long shelf life for timing devices allows you to worry less about excess inventory "expiring". Frequency controlled devices will still typically work many years after purchase. This causes less risk with older products.
Some industry suppliers won't hold frequency control products that are over a 2 years shelf life. However, a device's shelf life varies (many times up to 20 years). It's always important to test the timing or oscillator device before use. Talking with the frequency control manufacturer about a specific product's shelf life is also recommended.
3. Large Purchased Lot Sizes
Crystal oscillator manufacturers and suppliers are known for having large purchasing lot sizes.
For one, this helps better fulfillment responsiveness. This is, of course, because more product is able to be housed and for longer periods of time. Therefore helping to get products in your hand faster. This is typically the case for standardized parts and not so much custom.
Better yet, large lot sizes can help reduce price. This is mainly because of economies of scale and less of an innovatory storage burden on the manufacturer.
This can also make providing blanket orders easier and more timely for the manufacturer (and you).
And there you have it! Understanding these 3 tips should help you make crystal oscillator purchases quicker and easier than ever before.
