Vishay Extends Resistance Range of ORN Thin Film, Molded, Dual-In-Line Resistor Networks

Offering 13 standard resistance values over a wide resistance range of 49.9 Ω to 500 kΩ, the enhanced devices now offer designers a choice of higher and lower values in the same standard narrow-body SOIC gull wing package.

Offering higher precision than discrete chips, devices in the ORN series combine four isolated resistors in a 3.99 mm by 4.93 mm, eight-pin, surface-mount network. The devices offer a close ratio tolerance to ± 0.01 %, ratio stability characteristics (ΔR) of ± 0.015 % at 2,000 hours and + 70 ºC, and tight TCR tracking of ± 5 PPM/ºC.

With a 1.27 mm pitch and 1.73 mm maximum seated height, the ORN series is optimized for precision voltage divider, differential amplifier gain control, measurement circuitry, signal conditioning, and converter applications in industrial, process control, and medical instrumentation and imaging equipment. The devices offer a rugged molded case construction with no internal solder (JEDEC MS-012 variation AA package).

The ORN resistor networks feature power ratings of 100 mW at + 70 °C per resistor, extremely low noise of < - 30 dB, low voltage coefficients of < 0.1 ppm/V, and a temperature range of – 55 °C to + 125 °C. Offering lead (Pb)-free or lead terminations, the devices are compliant with RoHS Directive 2002/95/EC and halogen free according to the IEC 61249-2-21 definition.
