EL SEGUNDO, Calif. - May 2005 -- International Rectifier, IR®(NYSE: IRF), a world leader in power management technology, today announced the opening of a new customer service center in Shenzhen, a bustling international trade zone in China's Guangdong province.

Being close to its customers is a fundamental part of IR's business strategy. "We provide world-class service levels by listening to our customers' needs, understanding their businesses, and then helping them succeed with IR's best-in-class power management technology," said Paul Rolls, global vice president of services and new business development. "The new center will allow us to deploy supply chain solutions, value-added e-tools and benchmark services to provide superior service to the increasingly sophisticated markets in China," he added.

China's semiconductor market ranks as the world's third largest, exceeding $20 billion (USD) in sales. It is also one of the fastest-growing markets for power management technology with Shenzhen at the heart of this booming market.

"International Rectifier is committed to delivering service excellence to our global and local customer base enabling us to gain preferred supplier status, increase our contribution to the long-term success of our customers, and contribute to a healthier environment for everyone. Our service center will provide expertise in both our demand creation and demand fulfillment activities with our dedicated, highly-skilled local team of technical specialists," said Rolls.
