• Offers low DC resistance to minimize power loss
• Designed for compact mobile equipment applications

Chip Ferrite Bead Applications

• DC power line filtering
• Portable navigation devices
• Cellular phones
• Notebook PCs

Chip Ferrite Bead Procurement Notes

Verify the specific suffix against official documentation, as variations such as 'TN1D' or 'SN1D' may indicate different packaging or testing configurations. Confirm that the required operating temperature range aligns with the standard -55°C to +150°C specification. Ensure compatibility with flow or reflow soldering processes during assembly planning.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0603 footprint but higher current handling than standard beads allows. The 2.2A rating suits power supply inputs for portable electronics. Compare against larger packages like 0805 if higher current capacity is needed, or lower impedance variants if minimal signal attenuation is critical.

Chip Ferrite Bead Part Context

This part belongs to the BLM18KG series, which features enhanced current capabilities compared to conventional 0603 ferrite beads. The series is engineered to handle up to 6 amps in some variants, offering a cost-effective alternative to larger 0805 and 1206 wire-wound beads while maintaining low DC resistance.
