✔ RoHS Compliant / ✔ SMD / ✔ TDK Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC-DC Converter Output Filtering: The 4.7µH value provides effective ripple reduction for low-power converters, while the 500mA current rating comfortably handles typical portable device load demands.
- IoT & Wearable Battery Management: With a low 300mΩ DCR, this inductor minimizes I²R losses, extending battery life in always-on wireless sensor nodes and smart wearables.
- RF Module Decoupling: TDK’s ferrite construction offers stable inductance over frequency, making the MLZ2012M4R7WT000 suitable for blocking high-frequency noise in Bluetooth or Wi-Fi front-end stages.
Key Features & Advantages
- Compact SMD Package: The small footprint saves PCB real estate, enabling denser layouts in space-limited designs without sacrificing performance.
- Precise 4.7µH Inductance: Tight tolerance ensures consistent filtering behavior, reducing the need for compensation circuitry in sensitive analog paths.
- Low DCR for High Efficiency: The 300mΩ maximum DC resistance contributes to lower thermal stress and higher overall system efficiency, especially under continuous 500mA load.
Frequently Asked Questions
- Q: What makes MLZ2012M4R7WT000 different from a standard chip inductor?
A: This TDK part uses a multi-layer ferrite material that provides stable inductance up to higher frequencies, making it more effective for EMI suppression than standard air-core or wire-wound inductors of the same value. - Q: Is MLZ2012M4R7WT000 RoHS compliant?
A: Yes, as a TDK product, it is standardly RoHS compliant and lead-free. - Q: What is the MOQ?
A: We support small batch orders and full BOM kitting at SZYY.
