CZP1JFTTD121P

Overview

The CZP1JFTTD121P is a multilayer power ferrite bead manufactured by KOA Speer Electronics, Inc. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 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 rating of 2 A and has a maximum DC resistance of 100 mOhms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• Multilayer construction designed for high-current power line applications
• Compact 0603 surface-mount footprint for space-constrained PCB layouts
• High saturation current capability suitable for power filtering

Applications

• Power supply output filtering
• DC-DC converter noise suppression
• High-current signal line EMI reduction

Procurement Notes

Verify the specific impedance value against official datasheets, as distributor listings may contain conflicting data regarding 30 Ohm versus 120 Ohm specifications. Confirm the maximum DC current rating, noting discrepancies between 2 A and 3 A claims in various sources. Ensure the part number suffix matches the required tolerance and packaging format for your production needs.

Selection Notes

Select this component when a compact ferrite bead capable of handling significant DC current is required for power rail filtering. The 0603 package offers a balance between size and current capacity compared to smaller packages. Consider the 120 Ohm impedance at 100 MHz for effective high-frequency noise attenuation while maintaining low DC resistance to minimize voltage drop in high-current paths.

Part Context

This part belongs to the CZP series of multilayer power ferrite beads from KOA Speer. These components are engineered to provide effective electromagnetic interference suppression in circuits carrying substantial direct current. The series utilizes proprietary multilayer technology to achieve high saturation characteristics within small surface-mount footprints, making them suitable for modern dense electronic designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with other manufacturers requires matching impedance, current rating, and package dimensions.
