Epcos offers leaded overcurrent PTC thermistors (B598*C0120A570) for power-line applications in lead-free versions. The high-temperature solder in these protective components is entirely lead-free, and the concentration of lead bound in the ceramic does not exceed 0.1 percent. The resistance tolerance of the devices is 20 percent. Their maximum voltage is 265 V. These components are available in a resistance range from 10 to 120 Ω. Depending on the type, the release current ranges from 75 to 330 mA. The whole series has UL certification and its VDE approval will shortly be concluded.
