Hello @danny.nguyen

Delta Electronics/Cyntec does not list a shelf life for part number [SDER041H-2R2MS](https://www.digikey.com/en/products/detail/delta-electronics-cyntec/SDER041H-2R2MS/9761210?s=N4IgTCBcDaIMoBECiAlADAFgIwAkC0YKYAsnCALoC%252BQA)

Hi Anthony,

can you help to ask the Manufacture. I think they have the internal Doc to control the part in their store.

Thanks,  
Danny,

danny.nguyen, traditionally, shelf life will not apply to this kind of part. Check out this particular post I made a while back on shelf life, click [here](https://forum.digikey.com/t/useful-information-on-shelf-life/7112). Passive parts usually don’t age like sensitive adhesives or other chemicals. Most passive parts have indefinite shelf lives.
