Wirebondable 1 mm² Thin Film Chip Resistors With Resistance to 100 MΩ

Vishay Intertechnology, Inc. introduced the industry's first wirebondable thin film chip resistors with compact 40 mil by 40 mil (1 mm by 1 mm) footprints to feature high resistance to 100 Mohms. The new CS44 series features low TCR down to ± 50 ppm/°C and tolerances to ± 0.5 %.

Based on a chromium silicon thin film resistive element, CS44 series devices offer higher density, ohmic values, and performance when compared with their thick film counterparts. The resistors provide excellent stability of 0.1 % for 2,000 hours at rated power and + 70 °C for high-reliability industrial, medical, military, and aerospace equipment. In these applications, the CS44 resistors can save PCB space and reduce weight by replacing several 20 mil by 20 mil resistors.

The CS44 series offers a wide resistance range from 400 kΩ to 100 MΩ, very low noise of < - 20 dB typical, and thermal EMF of < 0.01 µV/°C. The RoHS-compliant devices offer rated power of 0.380 W at + 70 °C, 100 V limiting element voltage, and a - 55 °C to + 155 °C operating and storage temperature range.

Samples and production quantities of the CS44 series are available now, with lead times of 12 weeks for larger orders. Pricing for U.S. delivery starts at $8 per piece.
