Low-ESR tantalum chip capacitors

15 October 2008 Passive Components

New from Vishay is the TR8 series of moulded MicroTan tantalum chip capacitors that provide low ESR values of 0,8 Ω (at 100 kHz and 47 μF) in the 0805 case size, and 1,5 Ω in the 0603 case size.

Low ESR values, combined with small footprints, allow for greater efficiency in audio filtering and signal processing applications, while requiring less PCB space. The new TR8 capacitors are intended for applications in cellphones, digital cameras, MP3 players and other portable devices.

Like all series within the MicroTan family, the TR8 is fully RoHS-compliant and halogen-free. The devices feature lead-free, L-shape facedown terminations for better contact to the solder pad than traditional facedown style terminations. In addition, their rectangular moulded case encapsulation helps to streamline PCB assembly.

Capacitance values for the TR8 series range from 1,0 μF to 220 μF, with standard capacitance tolerances of ±10% and ±20%. Voltage ratings range from 4 W V d.c. to 16 W V d.c. The operating temperature range for the devices is -55°C to +85°C, or +125°C with voltage derating.
