Scottish electronics component manufacturer Wolfson Microelectronics has allegedly lost Apple as a customer.

Reports coming in this morning through financial wire services indicate the firm has confirmed the loss of one of its most important clients, believed to be Apple. Wolfson until now has been supplying some digital audio components for iPods, but these reports indicate it has failed to secure the supply deal for future generations of the Apple device.

Wolfson reports it has not been reselected by the customer (which company management have not named) for supplying components for a new iPod, "due to be launched in the third quarter of 2008."

Personal media players (PMP) represent 24 per cent of Wolfson's total sales, Apple is the company's largest customer. The products affected are understood to be Apple's new iPod nano and iPod touch players.

Citigroup estimates the Apple deal dropped $41 million to Wolfson's 2007 revenues, 15 per cent of the company's total revenue.

Second quarter revenue is expected to be impacted by Apple's decision.
