TAIYO YUDEN Expands Its Lineup of the Metal Power InductorMCOIL?
Achieving a Reduction in the DC Resistance by 20% of the Company?s Previous Product, Thereby Preventing the Generation of Heat in Power Supply Circuits
(PresseBox) - Tokyo, May 15, 2014? TAIYO YUDEN CO., LTD. today announced the addition of eight items including the ?MDMK4040T1R0MM? (4.0 x 4.0 x 1.2mm, the maximum height value), which has an approximately 20% reduced DC resistance than the company?s previous product, to its metal core SMD power inductors (MCOIL?, MD Series).
This product is a power inductor for choke coil applications developed for use in power supply circuits of tablet devices as well as HDDs and SSDs. While this product retains the high DC bias characteristic, which is a key feature of the metal power inductor MCOIL?using the company?s proprietary metallic magnetic materials, the DC resistance has been reduced by approximately 20% from 47 m? to 36 m? as compared to TAIYO YUDEN?s previous product ?MDMK4040T1R0MF? (4.0 x 4.0 x 1.2mm, inductance value of 1.0 ?H), and the temperature rise current has been increased by approximately
30% from the conventional 3.5 A to 4.5 A. Production commenced in April 2014 at the company?s Nakanojo Plant in Gunma Prefecture, Japan at a production rate of 10 million units per month for the entire ?MDMK4040 series?. Technology
Background
The metal power inductor MCOIL?, which is one of the super high-end products of TAIYO YUDEN, achieves an extremely high DC bias characteristic with a small and thin structure, and has gained popularity in choke coil applications developed for use in power supply circuits of smartphones as well as small and
thin digital devices. The ?MDMK4040? that has currently been added to the lineup is being adopted in tablet devices as well as HDDs and SSDs.
With continuing advancements in high-definition screens and thinner casing of tablet devices, the use of the metal power inductor, which is compatible with high current values, is being promoted as the power inductor in power supply circuits. Also, due to the fact that storages such as HDDand SSD are sensitive to heat, power supply circuits with low amounts of heat generation are required.
In view of this, TAIYO YUDEN has revised the core design of the ?MDMK4040?, and has been able to prevent the generation of heat and improve the temperature rise current by reducing the DC resistance. We will continue to actively promote the product development of the metal power inductorMCOIL? and expand its lineup to address the ever-growing demand of the market.
