The new card, like all other Panasonic SD and SDHC Memory Cards, is extremely reliable even under severe temperature conditions. Since the cards incorporate an industrial-grade flash memory, they work in temperatures ranging from -25°C to +85°C, while consumer-grade flash memory only guarantees 0°C to +70°C, thus ensuring consistent performance regardless if the user is skiing or snowboarding or if the SD Memory card is left in a hot car.
