NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device is
mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal equilibrium
has been reached under these conditions.
NOTE: External tuning capacitor must be used for proper operation.
NOTE 1: This parameter is defined in accordance with JEDEC Standard 65.
