TDK launched the latest EPCOS micro sound table filter
TDK has launched the first product in the latest EPCOS (Epskus) microphone filter series -EPCOS B4300 GPS filter. This GPS filter is certified by the AEC-Q200 standard. It is currently the smallest among similar products in the world and can adapt to the harsh use environment of automotive electronic systems. In addition to the compact structure, another significant feature of this component is that its electrical performance is excellent. For example, the insertion loss is only 1 dB, and the attenuation of the blocking band is also very high. The interference from the mobile phone frequency band can reach 45-50 dB.
Due to the use of CSSP. Technology (that is, "chip size sound packaging"), the new GPS filter structure is extremely small.
CSSP is first developed for mobile phones. Now this technology is further optimized, which can meet the high reliability requirements of the automotive industry. The pins adopted by the new B4300 GPS filter are compatible with the existing GPS filter type pins that are currently used on the mobile phone. In this way, it is easier for developers to use the existing GPS mobile phone solutions for car applications. This GPS filter is the first representative product in the new sound table filter series, which is used for car information and communication systems, including GPS, Galileo and Glonass navigation, as well as GSM, CDMA and W-CDMA mobile technology wait. In the future, the new series of products will be extended to all common frequency bands. It will not only have a single filter, but also the di, one filter and dual instrument produced by optimized CSSP packaging technology.
