Stackpole Announces Change from Tinned Copper Lead Wire to Copper Plated Steel for Carbon Film and Jumper Wire

New lead wire will help offset the dramatic increases in price of copper

RALEIGH, NC (May 31, 2006) - Stackpole Electronics, Inc. today announced they would be changing the lead wire material on their standard carbon film and jumper wire products (CF and JW series) from tinned copper to tinned copper plated steel.

Steel has been used as the base wire for leaded terminations for many years in a limited fashion. Recent improvements in the manufacturing processes for copper plated steel along with the recent spike in the price of copper have made copper plated steel an increasingly more popular choice as a lead material.

Stackpole's Chief Operating Officer, Jamie Mullane, explained the reason for the change. "For low cost resistors such as carbon film, the lead wire material can be as much as 60% of the total cost of the resistor. Since we're not able to control the price of copper, we are changing to a less expensive material to lessen the effects of rising precious metal costs on our customers."
