** Bourns follows the prevailing deﬁ nition of “halogen free” in the industry. Bourns considers a product to be “halogen free” if (a) the Bromine (Br) content is 900 ppm or less;

(b) the Chlorine (Cl) content is 900 ppm or less; and (c) the total Bromine (Br) and Chlorine (Cl) content is 1500 ppm or less.

Speciﬁ cations are subject to change without notice.

The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time.

Users should verify actual device performance in their speciﬁ c applications.

MF-RX Series - PTC Resettable Fuses

Product Dimensions

Advantages

■ Resettable feature with overtemperature and overcurrent protection

can save expensive components from having to be replaced after

tripping, e.g., transformers with built in thermal fuses

■ Faster than bimetallic switch designs that take on average

approximately 30 seconds to cool down and reset

■ Generally lower electromagnetic interference than bimetallic switches

Beneﬁ ts

■ Reduced repair and replacement costs

■ Reduced nuisance tripping

■ Combined overcurrent and overtemperature protector in one device
