HF70ACC321611-T

Chip Ferrite Bead Overview

The HF70ACC321611-T is a single-line ferrite bead chip from the HF-ACC series, manufactured by TDK Corporation. It features a 1206 (3216 metric) surface-mount package with dimensions of 3.20mm x 1.60mm and a maximum height of 1.30mm. The component provides an impedance of 26 Ohms at 100 MHz and supports a maximum rated current of 1.5A. Its DC resistance (DCR) is maximized at 40 milliohms. Designed for commercial applications, it operates within a temperature range of -40°C to 125°C. The device is RoHS3 compliant and classified under ECCN EAR99.

Chip Ferrite Bead Feature Summary

• Provides signal line filtering with specified impedance characteristics at high frequencies
• Supports high current handling capabilities suitable for power integrity applications
• Utilizes a compact surface-mount footprint for automated assembly integration

Chip Ferrite Bead Applications

• High-speed digital signal line noise suppression
• Power distribution network filtering in electronic circuits
• EMI reduction in consumer electronics and computing hardware

Chip Ferrite Bead Procurement Notes

Verify component authenticity through authorized distributors as the part status is Not Recommended for New Designs (NRND). Confirm RoHS3 compliance and MSL Level 1 status for storage and reflow soldering requirements. Check for official Product Change Notices regarding the HF-ACB/ACC series discontinuation timeline before finalizing procurement plans.

Chip Ferrite Bead Selection Notes

Select this component when a 1206 footprint ferrite bead with 1.5A current rating and 26 Ohm impedance at 100 MHz is required. Ensure the application environment stays within the -40°C to 125°C operating range. Consider the low DCR value for minimal voltage drop in power lines. Verify that the commercial grade specification meets the design requirements instead of automotive standards.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the HF-ACC series, which is designated for commercial-grade applications. It is distinct from the HF-ACB series, which typically offers lower current ratings, and the TD25 suffix variants used for automotive AEC-Q200 qualification. The HF-ACC series focuses on balancing impedance performance with higher current capacity for general-purpose electronic devices.

Chip Ferrite Bead Replacement Considerations

Public confirmed substitutes include MPZ2012S300AT000 from TDK. Alternative options from other manufacturers such as MI1206K260R-10 from Laird-Signal Integrity Products are also documented. Verify electrical parameter equivalence before substitution.
