The MAMK2520H1R0M from TAIYO YUDEN is a wire-wound metal power inductor from the MCOIL™ family. It uses metallic magnetic material with excellent DC-bias characteristics and is designed for energy storage, power filtering and noise suppression in compact DC/DC converter and power-supply applications. Its nominal inductance is 1.0μH with ±20% tolerance, measured at 2MHz.
The device has a maximum rated current of 3.1A. Saturation current is 4.3A maximum and 4.8A typical at a 30% inductance reduction, while temperature-rise current is 3.1A maximum and 3.4A typical at a 40°C temperature rise. These characteristics make it suitable for compact power circuits requiring high current capability.
The MAMK2520H1R0M provides low conduction loss with a maximum DC resistance of 45mΩ and a typical value of 37mΩ. Its metal-core wire-wound construction combines low Rdc with strong DC-bias performance for power-supply lines in mobile devices, communication equipment and compact DC/DC converters.
The inductor uses a 1008 / 2520 EIA/JIS case size, measuring 2.5 ±0.2mm × 2.0 ±0.2mm with a maximum height of only 1.2mm. Its operating-temperature range is -40°C to +125°C including self-generated heat. It supports reflow soldering and is RoHS compliant, REACH compliant and halogen-free.
TAIYO YUDEN has subsequently renamed the MAMK2520H1R0M. For general equipment and mobile applications, the official preferred replacement is LSAPB2520MKT1R0M, which is currently listed as Mass Production (Preferred).
