Resonator 20MHz SMD (Strip of 10)

This is a 10-pack of 20MHz resonators in a tiny SMD package. Resonators function like crystals but stick closer to their specified frequency over a full temperature range. These resonators possess an initial frequency tolerance of ±0.5% and a load capacity of 15pF.

These specific resonators were once used in a multitude of our products but, sadly, are no longer needed. We have made them available at a drastically reduced price for anyone who could possibly use one (or 10) of these handy little ICs.

Note: Since this product belongs to our Ding & Dent category, once we are out of stock we will not carry it again. Get them while you can!

Resonator 20MHz SMD (Strip of 10) Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

3 Soldering

Skill Level: Competent - You will encounter surface mount components and basic SMD soldering techniques are required.
See all skill levels

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

    What is the exact part number of these?

  • liudr / about 6 years ago / 1

    Does this sparkfun FreqCtrl library part match the resonator?


    I measured the dimensions of the pads and they seem to fit the spec sheet's land patterns. Just trying to confirm with the pros. Thanks.

    I will probably get some of these since once they go out of stock I can't get anymore. Even though I'll most likely never use them I know if I don't get them I'll probably need some.

    Sorry I'm not firing on all cylindars today.... This is a clock pulse, not a piezo element (i.e. it doesn't generate or pickup audio) right?

    • This is an alternative to a 20 MHz quartz crystal. It is used exactly the same way, except the typical load capacitors are built in. Instead of quartz being used for the frequency reference, it uses ceramic. It does not generate or pickup audio in the human range, but it might be sensitive to audio at 20 MHz. Compared to a quartz crystal frequency reference, these have much poorer initial frequency specification (parts per 1000 (ppt) vs parts per million (ppm) ) but are specified to operate over a wider temperature range and drift less over that range than quartz crystals. They are also cheaper and smaller.
