89 As featured with all five high temperature Multifuse ® families, the Bourns ® Model MF-FSHT series utilizes Bourns’ innovative freeXpansion ™ design that enables higher hold current ratings (Ihold), improved resis- tance stability, and higher maximum voltage ratings (Vmax), all delivered in a smaller foot- print. This Multifuse ® model family provides increased resettable fuse performance and is designed to reduce the risk of generating nuisance tripping at elevated temperatures between 85°C and 125°C. The new Multifuse ® MF-FSHT model fam- ily is available in a small EIA 0603 footprint, and further expands Bourns’ leading line of high-temperature rated polymer PTCs that include the radial leaded MF-RHT model family and the surface mount MF-SMHT, MF-USHT, MF-NSHT and MF-PSHT model families. These new models also provide enhanced thermal derating performance at higher temperatures, thereby allowing de- signers to benefit from higher Ihold and Itrip current ratings at elevated temperatureswhile using one of the industry’s smallest SMD foot- prints. Except for the MF-FSHT model family, the other listed Multifuse ® model families are Automotive Grade and AEC-Q200 compliant. The latest Bourns ® Multifuse ® model is the MF-MSHT series, which is also Automotive Grade, high temperature rated, AEC-Q200 compliant and available in a standard 1812 surface mount package. In addition, the series features a low thermal derating factor with a maximum voltage range of 9V – 42V, and a hold current range of 200mA – 1.75A. Design- ers of automotive applications will find the 125 °C rating of this new series a robust choice for overcurrent protection that supports their broad temperature requirements.

Fascinating Nonwovens Founded in 1879, Sandler is now one of the top nonwovens producers worldwide. At the company headquarters in Schwarzenbach/Saale Sandler develops and manufactures nonwoven panels and roll-goods for construction/engineering, filtration, home textiles, hygiene, transportation and wipes. In 2016, the first foreign subsidiary – Sandler Nonwoven Corporation - started production in Perry, Georgia, USA. Drive Better with Nonwovens With over 30 years of experience in the industry and with inno- vative and sustainable product solutions, Sandler now ranks among the leading suppliers to the global automotive industry. In interior applications, light- weight sawasorb ® absorber nonwovens are utilised in various components, contributing to good acoustics. In exterior applications, such as engine cover, underbody shield or wheel house arches, fluid- and dirt-repellent sawasorb ® exterior nonwovens offer a textile alternative. Composites made from self- supporting nonwoven panels and carbon- or glass-fibre- reinforced cover layers provide the basis for lightweight components that feature high mechanical stability. sawaform ® nonwovens for self- supporting and temperature- stable moulded parts allow for deep mouldings with excellent contour precision. Sandler cabin air filter media bring good air quality to vehicles and protect passengers from allergenic particles. As part of a composite material, fuel filter media contribute to more efficient combustion of fuels and protect the engine as well as adjoining units. Soft and air-permeable Sandler nonwovens for seat upholstery feature excellent drapeability, low creasing and a high recovery rate.

These re- quirements make Bourns’ high temperature PPTC devices an ideal choice for cost-effec- tive overcurrent protection solutions that re- duce the risk of generating nuisance tripping at elevated temperatures up to 125 °C in these high-growth applications. Plus, the Automo- tive Grade PPTC model families are advanta- geous to automotive and industrial designs as their high temperature polymer material offers heightened protection against solvent penetration. Solvents can cause resistance drift (increase) in a variety of polymer-based resistive components including PPTCs. This increase in resistance may, in turn, generate undesirable nuisance tripping by the PPTC because less current is required to trip the device.
