Tantalum Chip Capacitors with ESR of 0.8 Ohms
Vishay Intertechnology Inc. has released the TR8 series of molded MicroTan tantalum chip capacitors that provide ultra-low ESR values of 0.8Ω (at 100kHz and 47μF) in the 0805 case size, and a low 1.5Ω in the 0603 case size. Low ESR values, combined with small 0603 and 0805 footprints, allow for greater efficiency in audio filtering and signal processing applications, while requiring less PCB space. The TR8 capacitors are intended for applications in cell phones, digital cameras, MP3 players, and other portable devices. The TR8 is fully RoHS-compliant and halogen-free in accordance with Vishays commitment to supporting environmentally friendly "green" initiatives. The devices feature lead (Pb)-free, L-shape facedown terminations for better contact to the solder pad than traditional facedown-style terminations. In addition, their rectangular molded case encapsulation helps to streamline PCB assembly.
