LONDON Ė The prices of discrete electronic components are set to increase in the fourth quarter of 2010 as the lead times for obtaining those products lengthen, according to the market research firm, iSuppli.
Prices for those components - including bipolar power, power MOSFETS, small signal transistors and rectifiers Ė will then decline in the first quarter of 2011 as demand softens during the seasonally slow period, but buyers may still find it difficult to get parts. Delivery lead times for discrete components will continue to extend well beyond normal parameters, maybe by as much as 20 weeks or more in some cases, according to iSuppli Corp. (El Segundo, Calif.).
For bipolar power discrete some suppliers are quoting lead times of 26 weeks or more. While iSuppli predicts these lead times will fall in the first half of 2011, they could remain bloated at about the 18-week range.
Similarly the power MOSFET market is seeing price rises and allocation of certain devices from suppliers including On Semiconductor, Fairchild Semiconductor, Infineon Technologies and International Rectifier, iSuppli said. While prices are expected to stabilize in the first half of 2011, iSuppli expects the market to continue to see bottlenecks despite production expansion efforts.
In the first quarter of 2011 iSuppli expects small-signal transistor lead times at levels 20 weeks or longer. Similarly lead times for rectifiers will continue to be unusually extended at 20 weeks or more.
