✔ RoHS Compliant  /  ✔ SMD  /  ✔ TDK Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• DC/DC Converter Output Filtering: The 3.3µH inductance combined with 500mA saturation margin stabilizes low-current rail outputs while the 200mΩ DCR minimizes conduction losses.
• Power Supply Decoupling for IoT Modules: Its SMD package allows direct placement near noise-sensitive ICs, and the 200mΩ resistance ensures minimal voltage drop under 500mA load peaks.
• Portable Audio Noise Suppression: TDK’s material technology provides consistent inductance across frequency, effectively attenuating switching noise without compromising audio signal integrity.

Key Features & Advantages

• Low DC Resistance (200mΩ): Reduces I²R losses in power paths, improving overall conversion efficiency in battery-operated devices.
• 3.3µH Stable Inductance: Ferrite core construction ensures minimal inductance roll-off at rated current, delivering reliable filtering performance.
• Compact SMD Footprint: Standardized 2012 package enables high-density PCB layouts without sacrificing electrical performance.

Frequently Asked Questions

1. Q: What makes MLZ2012M3R3ATD69 different from a standard 3.3µH chip inductor?
   A: TDK’s proprietary ferrite composition provides a flatter inductance vs. current curve, ensuring the 3.3µH value is maintained up to 500mA with only 200mΩ DCR.
2. Q: Is MLZ2012M3R3ATD69 RoHS compliant?
   A: Yes, as a TDK product, it is standardly RoHS compliant and lead-free.
3. Q: What is the MOQ?
   A: We support small batch orders and full BOM kitting at SZYY.
