GMLB-201209-0080Y-PY

Chip Ferrite Bead Overview

The GMLB-201209-0080Y-PY is a multilayer ferrite chip bead manufactured by Pulse Electronics. It features an SMD/SMT termination style and is housed in a 0603 (1608 metric) package. The component provides an impedance of 80 Ohms with a tolerance of 25%. It has a maximum DC resistance of 40 mOhms and supports a maximum DC current of 3 A. The device operates within a temperature range of -55°C to +125°C and is shielded.

Chip Ferrite Bead Feature Summary

• Shielded construction for electromagnetic interference suppression
• Multilayer ferrite technology for high-frequency noise attenuation
• Surface-mount design compatible with automated assembly

Chip Ferrite Bead Applications

• Power line filtering under 1 GHz
• Signal integrity enhancement in digital circuits
• EMI suppression in portable electronic devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'PY' against official Pulse Electronics documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with standard 0603 footprint dimensions during PCB layout. Cross-reference the part number alias GMLB-201209-0080Y-PY-RU if sourcing from distributors utilizing alternative naming conventions. Confirm RoHS compliance status through the manufacturer's latest datasheet.

Chip Ferrite Bead Selection Notes

Select this component when a low DC resistance of 40 mOhms is required to minimize voltage drop in power lines carrying up to 3 A. The 80 Ohm impedance at the test frequency makes it suitable for broadband noise suppression. The shielded variant reduces magnetic field radiation compared to unshielded equivalents. Ensure the operating temperature range meets the environmental requirements of the target application.

Chip Ferrite Bead Part Context

This part belongs to the GMLB series of multilayer ferrite chip beads produced by Pulse Electronics, now part of Yageo. The series offers various impedance values and current ratings in compact surface-mount packages. These components are designed for EMI/RFI suppression in consumer electronics, industrial controls, and communication equipment where space constraints and high performance are critical.
