CZB1EGTTP121P

Overview

The CZB1EGTTP121P is a multilayer ferrite bead manufactured by KOA Speer Electronics, Inc. It features a 0402 (1005 metric) surface-mount package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 50 mA and has a maximum DC resistance of 1.5 Ohms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• Multilayer construction for compact surface-mount integration
• Designed for low-speed signal line filtering applications
• High thermal stability across extended industrial temperature ranges

Applications

• Low-speed signal line noise suppression
• Electromagnetic interference (EMI) filtering in compact circuits
• Signal integrity protection in portable electronic devices

Procurement Notes

Verify the complete part number including suffixes against official KOA Speer documentation to ensure correct impedance and package specifications. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents prior to procurement. Ensure supply chain partners provide traceability records matching the specific manufacturing batch requirements for quality assurance purposes.

Selection Notes

Select this component when space constraints require a 0402 footprint for ferrite bead implementation. Evaluate the 50 mA current rating against the circuit's operational load to prevent saturation. Consider the 120 Ohm impedance value relative to the target noise frequencies at 100 MHz. Verify that the 1.5 Ohm DC resistance does not introduce unacceptable voltage drops in sensitive signal paths.

Part Context

This component belongs to the CZB series of ferrite chip beads from KOA Speer. The series utilizes multilayer technology to achieve high impedance in small packages. The CZB1EGTTP121P specifically targets low-speed signal lines, distinguishing it from high-current power rail variants within the broader product family.
