Development of World’s Smallest Commercially available MEMS Microphone by TDK

March 23, 2010 · Filed Under Trendy Products 

TDK MEMS microphonesTDK-EPC one of the group company of TDK, made an announcement on development world’s smallest MEMS microphones featuring a digital interface. The newly developed EPCOS T4030 bears a dimension of 3.25 x 2.25 x 1.1 mm making the new MEMS microphone about 60% smaller than available alternative products in the market. The small form factor results in a more compact design for mobile phones and other consumer electronic products such as MP3 players and digital cameras.
The EPCOS T4030 has a sensitivity of -26 dB FS (full scale) and a signal-to-noise ratio of 60 dBA. The distortion factor for EPCOS T4030 remains under 1 percent even at a sound level of 100 dB. The EPCOS T4030 is mostly insensitive to electromagnetic interface due to a digital PDM (pulse density modulation) output. In EPCOS T4030, two channels can be transmitted using only one signal line, resulting in simpler implementation of stereo application than in analog technology. The EPCOS T4030 has supply voltage range of between 1.64 and 2.86 V, plus a power consumption of 650 uA, and 10 uA in standby operation. The EPCOS T4030 is manufactured based on CSMP (chip sized MEMS package) technology, developed for SAW filters. The main applications for EPCOS T4030 are mobile phones, hand-free phones, MP3 players, laptop PCs, video and VoIP systems, telephone conference systems as well as microphone arrays.

  2. Development of High-Storage Capacity Linear Tape Open Cartridge by TDK | Japan Technology Information on March 29th, 2010 1:46 pm

    [...] TDK Corporation made an announcement on development and successful certification of company’s Linear Tape-Open (LTO) Ultrium 5 cartridge. The LTO Ultrium 5 data cartridge, is company’s fifth generation LTO product comes with data storage capacity of 1.5 TB (3.0 TB with 2:1 compression) and a maximum high data transfer speed of 140 MB/s ( 280 MB/s with 2:1 compression). For achieving this high storage capacity, TDK has used tap that is 12.65 mm wide and has 1,280 recording tracks, plus the tape thickness has been reduced in order for the single cartridge to hold more tape. The new LTO Ultrium 5 has been made with ultra-thin, dual-layer tape coating technology that controls the thickness of the magnetic layer on the nanometer scale, plus a special servo writer for recording high-precision servo signals. Furthermore, the LTO Ultrium 5 features a high-precision cartridge mechanism that seeks high-performance and high precision in every component including a high-precision leader pin and a reel hub for enhancing the straightness of the drum for precise drive access. The LTO Ultrium 5 has been developed to meet the demand for high-speed, high-capacity servers. TDK has already begun the mass production of the LTO Ultrium 5 . source Share and Enjoy: [...]

  3. Development of Pulse Transformer in SMD Design for LAN use by TDK | Japan Technology Information on April 5th, 2010 8:20 am

    [...] TDK Corporation has developed a series of SMD pulse transformer fir LAN application resulting in simplification of manufacturing processes. The new pulse transformer will allow the customers to employ automated placement of all components on the circuit board and using reflow solder, resulting in simplification of their manufacturing processes, according to the company. The new SMD design was achieved through application of advanced fully automated wire winding and packaging, replacing the manual processes. The new product is used for transmission of differential pulse signals in high-speed LANs such as 100BASE-TX. The newly developed ALT4532-001T series of pulse transformers are targeted to be used in digital consumer electronic applications such as games consoles, internet radios and PCs featuring LAN connectivity. The new ALT4532-001T series of pulse transformers features an inductance of at least 200 uH and an insertion loss of not more than 1.5 dB. Advantage of SMD design becomes apparent when the pulse transformer is used in combination with common-mode filter resulting in elimination of differential noise in addition of reducing the mounting area by about 35 percent in comparison to the previous version. The mass production of the new ALT4532-001T series of pulse transformers has already begun. source Share and Enjoy: [...]
