CIC31J501NE

Chip Ferrite Bead Overview

The Samsung Electro-Mechanics CIC31J501NE is a single-line power line ferrite bead designed for surface mount applications. It features a 1206 (3216 Metric) package with dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm). The component provides an impedance of 500 Ohms at 100 MHz and supports a maximum current rating of 3A. Its maximum DC resistance (DCR) is 50 mOhm, ensuring low insertion loss in power circuits. The device operates within a temperature range of -55°C to 125°C and complies with RoHS3 standards.

Chip Ferrite Bead Feature Summary

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value of 500 Ohms at 100 MHz against your circuit requirements. Confirm the 3A current rating and 50 mOhm DCR limits are suitable for your power design. Ensure the 1206 package size fits your PCB layout constraints. Check for RoHS3 compliance if required by your manufacturing standards. Validate the operating temperature range of -55°C to 125°C for your environmental conditions.

Chip Ferrite Bead Selection Notes

Select this component when high impedance is needed for power line filtering without excessive voltage drop. The 3A rating makes it suitable for higher current applications compared to standard signal beads. Consider the 1206 footprint for space-constrained designs requiring robust thermal performance. Compare DCR values to minimize power loss in efficiency-critical systems.
