Additional Details

The BB502CBS-TL-E comes in a small surface-mount package (typically SOT-23 or similar). Key specifications include a capacitance range that varies with the applied reverse voltage, a high tuning ratio (the ratio of capacitance at a low voltage to capacitance at a high voltage), and a low series resistance. The reverse voltage range is typically from 0V to several volts. The exact capacitance range and tuning ratio depend on the specific part number and operating conditions. The operating temperature range is generally from -55°C to +125°C.

When using the BB502CBS-TL-E, it is important to ensure that the maximum reverse voltage rating is not exceeded. The capacitance-voltage characteristic should be consulted to determine the appropriate reverse voltage for the desired capacitance value. Proper PCB layout techniques should be used to minimize parasitic capacitance and inductance, which can affect the performance of the tuning circuit. Always consult the datasheet prior to use.
