SMD Metal-Foil-on-Ceramic resistors boast high surge tolerance, low self-heating
TT Electronics announced the introduction of its Metal Foil Chip (MFC) resistors. The MFC series uses metal foil on ceramic technology, which combines the heat spreading properties of a ceramic substrate with the surge tolerance of a bulk metal alloy resistance element. This, in turn, offers lower self-heating levels than thick-film or metal strip resistors and better surge tolerance than thick-film options, making these resistors particularly well-suited for automotive, industrial, and medical […]
Anti-sulphur, high-reliability thin-film chip resistors optimized for harsh environments
TT Electronics, a global provider of engineered electronics for performance critical applications, announced the APC Series resistors, its family of high reliability surface mount resistors that have been qualified for use in environments exposed to sulphur-bearing gasses. Featuring stability and tight tolerances, APC resistors are optimised for high precision analogue circuits deployed in polluted environments […]
