TT Electronics BI Technologies Electronic Component Division recently developed RoHS-compliant thin film resistor networks. The networks are comprised of a matte tin finish over copper lead frame.  

"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.

To distinguish from existing products, a suffix "LF" is added to existing part numbers. The packing labels will also identify the products as RoHS-compliant.  BI will continue to support the original lead-bearing thin film resistor networks as well.

Packaged in all-plastic molded packages, 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.  

Network series available include 6XX Nichrome on ceramic and SXX Nichrome on silicon families.
