- Devices are not designed to be wave soldered to th ~~e b~~ ot ~~tom~~ side of the board. - Devices can be cleaned using standard industry methods and solvents. - **Note:** - If reflow temperatures exceed the recommended profile, devices may not meet the performance requirements. ## ~~**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. The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time. Specifications are subject to change without notice. Users should verify actual device performance in their specific applications. ## **MF-SM/250 - Telecom PTC Resettable Fuses** ## ~~**Typical Time to Trip at 23 °C**~~ **==> picture [316 x 243] intentionally omitted <==** **----- Start of picture text -----**
