32kHz crystal

[Rajinder]

Hi,
I have noticed that a 32kHz crystal has malfunctioned i.e. not oscillating, it is cracked, what could cause this to happen?
Thanks

Hello,

When you say it is cracked, it must have been mechanicaly mistreated.
Crystals are small pieces of quartz crystal or a synthetic quartz grown crystal.

They can not withstand bumping.

you sure you are looking at the crystal ?

most will be in a tiny metal tube with 2 wires out one end less common for them is like in the link that Bertus supplied

and occasionally will be in a epoxy type encapsulation like ......

So is it like one of those or something completely different ?

Also as Bertus said, it would only crack is physically struck. They only have a tiny current / voltage associated with them

Hello,

How did you test the crystal?
When it is a single crystal, you will need to make an oscillator with it.
In the attached PDFs you will find some oscillator schematics and other info for crystals.
