Malvern, Pa. Vishay Intertechnology, Inc. has released the TR8 series of molded MicroTan tantalum chip capacitors that provide ultra-low equivalent series resistance (ESR) values of 0.8Ω (at 100 kHz and 47 uF) in the 0805 case size, and an industry-low 1.5Ω in the 0603 case size.
Low ESR values, combined with a small footprint, allow for greater efficiency in audio filtering and signal processing applications, while requiring less PCB space, Vishay said. Applications include cell phones, digital cameras, MP3 players, and other portable devices.
Capacitance values for the TR8 capacitors range from 1.0 uF to 220 uF, with standard capacitance tolerances of ±10% and ±20%. Voltage ratings range from 4 WVdc to 16 WVdc. The operating temperature range is -55°C to +85°C, or +125°C with voltage derating.
Like all series within the MicroTan family, the TR8 is fully RoHS-compliant and halogen-free in accordance with Vishay's 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, Vishay said.
The capacitors are available in 8-mm tape-and-reel packaging per EIA-481-1 and 7-in (178-mm) standard reeling per IEC 286-3.
Pricing: $0.42 in small quantities, depending on case size.
Availability: Samples and production quantities are available now, with lead times of eight to ten weeks for larger orders.
