Voltage divider provides high stability
The TaNFilm voltage divider is ideal for battery monitoring, voltage references, voltage conversion, voltage regulators, logic-level conversion, DC/DC convertors and power supplies.
TT Electronics' IRC Advanced Film Division offers a precision chip voltage divider with either Tantalum Nitride (TaNFilm) technology for precision performance or Tantalum Ultride technology for ultra-precision and high stability circuits Both versions of the PFC Divider voltage divider are offered in a 1206 package compatible with automatic placement equipment

Resistors provide better surge protection
IRC Advanced Film Division has introduced a series of wire bondable chip resistors.
"While our TanFilm resistive elements provide superior environmental performance and precision, our Tantalum Ultride technology takes that a step further with the exceptionally tight TCR, tolerance and stability specifications", said Jerry Seams, Applications Engineering Manager for IRC Advanced Film Division.
"By offering the device in both technologies, we are able to provide our customers with a single package solution for any voltage divider application from voltage convertors and references to precision gain and frequency control.
The TaNFilm voltage divider is ideal for battery monitoring, voltage references, voltage conversion, voltage regulators, logic-level conversion, DC/DC convertors 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.
The TaNFilm PFC voltage divider features a resistance range from 10ohm to 150kohm, with a package power rating of 250mW.
The divider has a maximum voltage rating of 100V, absolute TCRs to +/-25 parts per million/C, and TCR tracking to +/-5 parts per million/C.
The operating temperature range is -65C to +150C.
The PFC voltage divider with Tantalum Ultride technology features a resistance range from 1Kohm to 50kohm, and a power rating of 50mW.
Absolute TCR is to +/-10parts per million/C, with TCR tracking to +/-1 parts per million/C and absolute tolerance to +/-0.02%.
Ratio stability at 70C ambient is better than 50 parts per million over 1000 hours at rated power.
The operating temperature range is from -55C to +125C.
IRC will also produce devices outside these specifications to meet customer requirements.
Both versions of the voltage divider feature wrap-around terminations with a nonleaching nickel barrier, and are available with standard Sn/Pb terminations or 100% tin (Pb-free).
