ABNQ00100505121Y00

Overview

The ABNQ00100505121Y00 is a shielded multilayer ferrite chip bead manufactured by Pulse Electronics. It features an SMD/SMT termination style within a 0402 (1005 metric) package. The component provides an impedance of 120 Ohms with a 25% tolerance and supports a maximum DC current of 350 mA. Its maximum DC resistance is 400 mOhms, and it operates reliably within a temperature range of -55°C to +125°C.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Multilayer ferrite technology for compact surface-mount integration
• Wide operating temperature range suitable for harsh environments

Applications

• High-frequency noise suppression in portable electronics
• Signal line filtering in communication modules
• Power rail decoupling in embedded systems

Procurement Notes

Verify the specific manufacturer part number against official Pulse Electronics documentation to ensure authenticity. Confirm that the shielding characteristics and impedance values match your circuit requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the 0402 package dimensions fit your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when space-constrained designs require effective high-frequency noise attenuation. The 350 mA current rating suits low-power signal lines rather than high-current power paths. Consider the 120 Ohm impedance profile for target noise frequencies around the standard test frequency. The shielded design offers advantages over unshielded beads in dense layouts where crosstalk must be minimized.

Part Context

This ferrite bead belongs to the ABNQ series from Pulse Electronics, designed for surface-mount applications. It utilizes multilayer ceramic technology to achieve high impedance in a small footprint. The series is engineered for reliability in consumer and industrial electronics requiring robust EMI suppression without significant signal degradation.

FAQ

What is the test frequency for the 120 Ohm impedance specification?

The impedance value is typically measured at 100 MHz, which is the standard test frequency for this component type.

Does the shielded design affect the DC resistance?

The shielded construction does not inherently increase DC resistance; the specified maximum DC resistance remains 400 mOhms regardless of the shielding feature.
