✔ RoHS Compliant / ✔ SMD / ✔ TDK Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC‑DC Converter Input/Output Filtering: The 3.3 µH inductance combined with a 200 mΩ DCR minimizes ripple while the 500 mA rating handles moderate load currents without saturation.
- Portable & IoT Devices: Its compact SMD footprint saves board space in wearables, sensors, and wireless modules where power integrity is critical at low currents.
- Noise Suppression in Power Lines: The MLZ series’ ferrite core provides high impedance at switching frequencies, effectively attenuating conducted EMI.
Key Features & Advantages
- Precision Inductance (3.3 µH): Tight tolerance ensures consistent performance in regulated power stages.
- Low DC Resistance (200 mΩ): Reduces I²R losses, improving overall circuit efficiency in battery‑powered applications.
- High Current Capability (500 mA): Rated for continuous operation without thermal degradation, even in confined spaces.
Frequently Asked Questions
- Q: What makes the MLZ2012M3R3HT000 different from a generic 3.3 µH chip inductor?
A: TDK’s ferrite material and multilayer construction deliver stable inductance over a wide frequency range, while the 500 mA saturation current ensures reliable performance under load. - Q: Is this part RoHS compliant?
A: Yes, as a standard TDK product, it is fully RoHS compliant and lead‑free. - Q: Can this inductor be used in high‑frequency DC‑DC converters?
A: Absolutely. With 3.3 µH and 200 mΩ DCR, it is well‑suited for converters operating in the 1–6 MHz range, such as those in portable electronics.
