Fullerton, Calif. In response to environmental regulations in the electronic component industry, TT Electronics BI Technologies Electronic Component Division has developed a series of RoHS-compliant thin-film resistor networks that is comprised of a 100% matte tin finish over a copper leadframe.
"We are pleased to offer RoHS-compliant thin-film resistor networks that are both backward compatible with existing leaded solder profiles and forward compatible with lead-free solder profiles," said Mike Torres, applications engineer and product marketing manager for BI Technologies Electronic Component Division, in a statement. "This compatibility will enable OEMs to integrate these networks into existing designs as well as new product designs."
RoHS-compliant versions are available for the company's 6XX Nichrome on ceramic, and SXX Nichrome on silicon families. There is no change in performance characteristics for compliant parts.
In order to distinguish the RoHS-compliant thin-film resistor networks from existing products, the company has added a suffix "LF" to existing part numbers. The packing labels will also identify the products as RoHS-compliant. The company said it will continue to support the original leaded thin-film resistor networks.
Packaged in all-plastic molded packages, the networks are fully compliant to RoHS Directive 2002/95/EC, with no exemptions. The devices undergo a process of anneal baking after tin-plating to reduce tin whisker growth.
The price of the RoHS-compliant resistor networks is comparable to the price of the original thin-film resistor networks. Typical pricing is $1.00 in quantities of 1,000.
