MMZ1608S301ATD25

Overview

The MMZ1608S301ATD25 is a single-line ferrite chip bead from the TDK MMZ Auto series, designed for automotive signal line applications. 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 300 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 500 mA. Its maximum DC resistance is 300 mOhms with a 25% tolerance. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Designed specifically for signal line noise suppression
• Compact 0603 surface-mount footprint

Applications

• Automotive electronic circuit protection
• Signal line EMI/RFI suppression
• Embedded processor and controller interfaces

Procurement Notes

Verify the specific suffix TD25 against official TDK documentation to confirm reel specifications and tape-and-reel parameters. Ensure the selected variant matches the required impedance and current ratings for the target application. Cross-reference the manufacturer part number with authorized distributor databases to confirm authenticity and compliance with RoHS3 standards before finalizing procurement orders.

Selection Notes

Select this component when a 300 Ohm impedance at 100 MHz is required for signal lines in automotive environments. The 500 mA current rating suits moderate signal currents, while the low DC resistance minimizes voltage drop. The wide operating temperature range ensures functionality in harsh automotive conditions. Verify that the 0603 package size fits the available PCB real estate constraints.

Part Context

This component belongs to the TDK MMZ Auto series, which specializes in ferrite beads for automotive electronics. The MMZ1608 designation indicates the 0603 case size. The 'S' suffix typically denotes specific impedance characteristics or material properties within the series, distinguishing it from other variants like the D or R series which may offer different current handling capabilities.

Replacement Considerations

Direct substitutes include other TDK MMZ Auto series parts with identical 300 Ohm impedance and 0603 packaging, such as MMZ1608R301ATD25, provided the higher current rating of the alternative does not conflict with design constraints. Verify pin compatibility and thermal performance before substitution.
