Resistors provide better surge protection
IRC Advanced Film Division has introduced a series of wire bondable chip resistors.
According to Jerry Seams, New Business Development and Applications Engineer for IRC Advanced Film Division, the design of the CHC-Precision BGA package provides customers with several advantages.
"The single-sided monolithic design allows us to eliminate parasitic effects due to wrap-around terminations", says Seams.
"Additionally, with a high precision device such as this, it is essential to be able to wash under the component in order to eliminate the detrimental shunting effects of uncleaned assembly process residues".
The CHC-Precision Series BGA Series networks are ideal for industrial applications, process control and monitoring, medical equipment, instrumentation and metering.
The CHC-Precision BGA Series resistor networks are available in 8- and 16-pad packages.
The ball grid array features a resistance range from 10ohm to 100kohm, with a maximum working voltage of 50V.
The device features TCR tracking to +/-5ppm/C, ratio tolerances to +/-0.05%, absolute tolerances to +/-0.1%, and absolute TCRs to +/-25ppm/C.
Operating temperature range is -55 to +150C.
IRC will also produce devices outside these specifications to meet customer requirements.
The CHC-Precision Series ball grid array uses IRC's patented TaNFilm (tantalum nitride) technology.
The TaNFilm process produces precision tantalum nitride thin film resistive elements that are immune from corrosion problems in humid environments.
The self-passivating properties of tantalum nitride result in a more stable, reliable resistive device.
This process allows IRC to manufacture custom circuit configurations and multiple resistance values without compromising tight tolerance or tracking characteristics.
Pricing for the CHC-Precision Series BGA package is US $1.00 each in quantities of 10,000 pieces.
Lead time is from stock to 10 weeks ARO.
