The UCB10-300T-RC is an ultra current ferrite bead manufactured by Allied Components International. It features a 0806 (2012 Metric) surface-mount package and provides 30 Ohms impedance at 100 MHz. The component supports a rated current of 4A with a maximum DC resistance of 20mOhm. It operates within a temperature range of -40°C to +125°C, ensuring stability in high-current power line applications.
Verify the specific datasheet version from Allied Components International before integration. Confirm that the 0806 package dimensions and thermal characteristics align with your PCB layout requirements. Ensure the 4A current rating meets the peak load demands of your circuit design to prevent saturation or excessive heating during operation.
Select this component when high current capacity is required alongside significant high-frequency attenuation. The 20mOhm DC resistance minimizes voltage drop in power lines compared to higher-resistance alternatives. Consider the 0806 package size as a balance between current handling and board space efficiency for power management modules.
This part belongs to the UCB series of ultra current beads from Allied Components International. It shares the family's focus on high-current power line applications but differs in package size and specific impedance characteristics from other series members like the MLB or HCB variants. The 'T' suffix typically indicates tape and reel packaging for automated assembly.
The impedance is 30 Ohms measured at a frequency of 100 MHz.
The maximum DC resistance is specified as 20mOhm.
