IRC's wire bondable chip resistors

TT Electronics IRC Advanced Film Division has extended the resistance range of its bondable chip resistors to 1 megohm while maintaining the TCR at 25ppm/C for medical electronics such as battery-operated implantable devices and hybrid circuit applications.

Designed to deliver precision and stability over time and temperature, the WBC series of ultra-miniature resistor chips combine IRC's tantalum nitride thin-film technology with silicon substrate processing to produce devices 20mil?. The WBC series is said to be the only available 1megaohm precision resistor in a miniature package with TCRs as low as 25ppm/C.

The WBC series of wire bondable resistor chips offer a resistance range from 10ohm to 1megaohm, with absolute tolerances to 0.1% and ratio tolerances (0303 chip) to 0.05%. The precision resistors feature a power rating of 250mW at 70C, with a rated operating voltage of 100V. Absolute TCRs are 25ppm/C, with tracking TCRs to 2ppm/C. The operating temperature range is -55C to 150C. Custom specifications are available.

The wire bondable chip resistors are available in 0202 and 0303 chip sizes, with optional gold backside metallization. The 0303 two-resistor center-tapped chips can be used in feedback circuits of amplifiers, where ratio matching, high power and close tracking between two resistors is critical.

Pricing for the WBC series resistors typically starts at $1 in quantities of 1,000.
