Storage Recommendations
The recommended long term storage conditions for Multifuse® Polymer PTC devices are 40 °C maximum and 70 % RH maximum. All devices should
remain in the original sealed packaging prior to use. Devices may not conform with data sheet specifications if these storage
recommendations are exceeded. Devices stored in this manner have an indefinite shelf life.
