• Compact surface-mount footprint suitable for space-constrained circuit designs
• Maintains stable electrical characteristics across a wide industrial temperature range

Chip Ferrite Bead Applications

• High-speed digital signal line filtering
• Power supply output noise reduction
• RF circuit interference suppression

Chip Ferrite Bead Procurement Notes

Verify the end-of-life status confirmed by the manufacturer product change notice dated June 1, 2020. Ensure replacement components match the 0402 package, 1.8 kOhm impedance at 100 MHz, and 200mA current rating. Confirm RoHS3 compliance and check for equivalent part numbers such as BLM15HD182SN1D or MMZ1005A182ET000 if availability is required.

Chip Ferrite Bead Selection Notes

Select this component when a low-profile ferrite bead is required for noise suppression in compact layouts. The 0402 size offers a balance between current handling capability and physical footprint. Verify that the 200mA saturation current meets the circuit requirements and that the 2.2 Ohm DC resistance does not cause unacceptable voltage drop in power lines.

Chip Ferrite Bead Part Context

This component belongs to the CIV05 series of ferrite beads from Samsung Electro-Mechanics. The series is engineered for general-purpose EMI suppression in consumer electronics and industrial equipment. The specific model utilizes standard ceramic ferrite materials optimized for high-frequency absorption characteristics.

Chip Ferrite Bead Replacement Considerations

Publicly confirmed substitute part numbers include BLM15HD182SN1D from Murata Electronics and MMZ1005A182ET000 from TDK. These alternatives share similar electrical specifications and package dimensions.
