CGS power resistors offered with a choice of tolerances
Tyco Electronics is releasing a new series of surface-mount power resistors in 1W, 2W, 3W and 5W packages with true pick-and-place suitability. Available in very wide value ranges from 10R – 2M for the 1W version and R10 – 2M for the 2W, 3W and 5W components in the E24 value grid, the new SM series power resistors are available in tolerances of 1 or 5 per cent.
The 1W version is only available in metal film format, whereas the 2, 3 and 5W versions are available in metal film and wirewound formats. The maximum operating voltage is 300V for the 1 and 2W devices and 500V for the 3 and 5W resistors. All SM series power resistors are offered on tape.
Suited to meet today's circuit design needs in applications such as consumer electronics, computers, telecommunications and control instruments, new CGS brand SM series power resistors offer users the ability to use true vacuum pick-and-place heads. There is no need for either the forming of leads or pincer tools for pick-and-place.
SM series power resistors benefit from a low-profile case design with flexible tinned copper terminations for reliable solder joints. All versions utilise a fully welded construction technique, unlike other designs that rely solely on tinned termination connections. These features allow SM series devices to withstand higher temperatures associated with reflow, vapour phase, or infrared (IR) manufacturing processes without degradation. The components are designed for a very wide operating temperature range from -55 up to +200degC, making them suitable for replacing leaded components.
