Due to a high volume of SSL and Hort applications, initial and comprehensive review timeframes are currently extended by 10 days each. Beginning April 11, review priority will be given to applications updating V5.0 products to V5.1, which may also impact review timeframes for all other SSL application types. Click here for more details about SSL application review timeframes, and here for more details about Hort review timeframes. Thank you for your understanding!


Testing Tightly Packed Arrays of LED Packages
