LMMGA322525T102NG

Chip Ferrite Bead Overview

The LMMGA322525T102NG is a power line ferrite bead manufactured by Taiyo Yuden in a 1210 (3225 metric) surface-mount package. It exhibits an impedance of 1 kOhm at 100 MHz with a tolerance of 30%. The component supports a rated current of 2 A at a temperature rise of 40°C and has a DC resistance of 0.1 Ohms. It operates within a temperature range of -40°C to +125°C, including self-generated heat.

Chip Ferrite Bead Feature Summary

• Provides high impedance for effective noise suppression on power lines
• Designed for high-current applications with a 2 A rating
• Utilizes a compact 1210 surface-mount footprint

Chip Ferrite Bead Applications

• Power line filtering in electronic circuits
• Noise suppression in high-current signal paths
• EMI reduction in portable devices

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value of 1 kOhm at 100 MHz and the 30% tolerance against official datasheets. Confirm the 2 A current rating applies under the standard 40°C temperature rise condition. Ensure the operating temperature range includes self-generated heat effects up to +125°C. Check RoHS compliance status through manufacturer documentation before integration.

Chip Ferrite Bead Selection Notes

Select this component when designing circuits requiring significant impedance at 100 MHz for power rail noise attenuation. The 0.1 Ohm DC resistance minimizes voltage drop in high-current paths. The 1210 package allows for space-constrained layouts while maintaining thermal performance suitable for environments reaching +125°C.

Chip Ferrite Bead Part Context

This ferrite bead belongs to Taiyo Yuden's lineup of passive components designed for electromagnetic interference suppression. It serves as a critical element in power integrity management, distinguishing itself from inductors by providing frequency-dependent resistive loss rather than energy storage. The 1210 form factor aligns with industry-standard board designs.
