Frequently Asked Questions
What inductance value and package size does the TDK MLZ2012M470W offer?
The MLZ2012M470W provides 47 µH of inductance in a 2012 (2.0×1.25 mm) chip package. This combination delivers significant low-frequency EMI attenuation in a footprint that fits comfortably on densely populated PCBs used in smartphones, wearables, and compact industrial sensor modules.
For which DC-DC converter topologies is the MLZ2012M470W best suited as an output filter inductor?
The 47 µH inductance of the MLZ2012M470W is best suited for low-frequency buck converter designs switching below 500 kHz, where high inductance reduces output current ripple to under 5% of load current at 3.3 V or 5 V rails. It is less appropriate for high-frequency converters above 1 MHz, where smaller 1 µH to 10 µH inductors are preferred to minimize core losses.
How does the MLZ2012M470W perform in automotive power conditioning compared to larger leaded inductors?
The MLZ2012M470W operates across -40°C to +85°C, covering the standard automotive temperature grade for non-powertrain electronics, while its 2012 SMD footprint eliminates the mounting hardware and solder-joint variability of leaded inductors. Its 47 µH value attenuates low-frequency conducted emissions on 12 V automotive bus lines, helping ADAS sensor modules and infotainment units meet CISPR 25 Class 5 radiated emission limits.
