Corpus Christi, Tex. TT electronics IRC Advanced Film Division offers its precision chip voltage dividers with either Tantalum Nitride (TaNFilm) technology for precision performance or Tantalum Ultride technology for ultra-precision and high-stability circuits. Designated the PFC Divider series, both versions are offered in a 1206 package.
While the TanFilm resistive elements are said to provide excellent environmental performance and precision, the TanFilm resistive elements also add exceptionally tight temperature coefficient of resistance (TCR), tolerance and stability specifications. The TaNFilm PFC voltage divider features a resistance range from 10 ohms (Ω) to 150 KΩ, with a package power rating of 250 mW. The divider offers a maximum voltage rating of 100 V, absolute TCRs to ±25 ppm/°C, and TCR tracking to ±5 ppm/°C. The operating temperature range is -65°C to +150°C.
The PFC voltage divider with Tantalum Ultride technology features a resistance range from 1 KΩ to 50 KΩ, and a power rating of 50 mW. Absolute TCR is rated to ±10 ppm/°C, with TCR tracking to ±1 ppm/°C and absolute tolerance to ±0.02%. Ratio stability at 70°C ambient is better than 50 ppm over 1,000 hours at rated power. The operating temperature range is from -55°C to +125°C. Custom specifications are available.
The TaNFilm voltage divider is suitable for battery monitoring, voltage references, voltage conversion, voltage regulators, logic-level conversion, DC/DC converters and power supplies, as well as COTS applications. The Tantalum Ultride voltage divider is specified for high-stability applications including medical CT, MRI, PET and ultrasound equipment; petrochemical equipment such as exploration and data logging instruments; instrumentation and test devices including DMMs, measurement bridges, strain gauge circuits and input attenuators; as well as military avionics and missile guidance.
Both versions of the voltage divider feature wrap-around terminations with a non-leaching nickel barrier, and are available with standard Sn/Pb terminations or 100% tin (Pb-free).
Pricing: $0.78 at quantities of 1,000.
