Bourns, a specialist manufacturer and supplier of electronic components for power, protection, and sensing solutions, has introduced its Multifuse Model MF-RHS High Temperature Radial Leaded Polymer Positive Temperature Coefficient (PPTC) Resettable Fuse Series.

Bourns’ new fuse series answers the need for broader high temperature PPTC protection solutions that meet increased working temperature and high-power rating requirements for a wide range of equipment, particularly in motor and industrial applications.

The new Model MF-RHS Series is based on Bourns’ advanced design that increases resettable fuse performance and supports an operating temperature range up to 125°C. Performance enhancements are comprised of an elevated 100A maximum current rating (Imax), including a hold current rating range (Ihold) from 3.5A to 13.0A at 16V maximum rated voltage and enhanced resistance stability in a smaller PPTC chip size. The series’ smaller package dimension and low power dissipation can also help increase overall power application efficiency.

The Bourns Multifuse Model MF-RHS Series is available now and is RoHS compliant* and halogen free**. The series is also UL and CSA recognized and the products are manufactured in one of Bourns’ IATF 16949 certified facilities.

*RoHS Directive 2015/863, Mar 31, 2015 and Annex.

**Bourns considers a product to be “halogen free” if (a) the Bromine (Br) content is 900ppm or less; (b) the Chlorine (Cl) content is 900ppm or less; and (c) the total Bromine (Br) and Chlorine (Cl) content is 1500ppm or less.
