PFC Series Precision Thin Film Chip Resistors
The datasheet focuses on the IRC TaNFilm™ PFC Series, which provides precision thin film chip resistors featuring the Tantalum Nitride resistor film system. These resistors are available in several chip sizes: 0402, 0603, 0805, 1206, 1505, 2010, and 2512. The PFC Series is designed for Commercial-Off-The-Shelf (COTS) applications, and it offers options for both standard 60/40 Sn/Pb and Pb-free (RoHS compliant) terminations. These resistors are characterized by an absolute Temperature Coefficient of Resistance (TCR) as tight as ±10ppm/°C. In addition, MIL (military) screening is available for applications that require higher reliability and rigorous testing.
The resistors in the series boast an “ultra stable” Tantalum Nitride resistive film system, which ensures long-term life stability and environmental robustness. The passivated film is designed to maintain performance over time and in various conditions. The manufacturing process is shared with the Military Series, thereby ensuring that these precision chips retain superior environmental performance as well.
The PFC Series is specifically engineered to maintain initial precision even in harsh surface mount soldering environments. The components feature wrap-around terminations with a non-leaching nickel barrier that contributes to the production of high integrity solder connections.
Electrical Data
The chip resistors have the following power and maximum voltage ratings:
- W0402: 50 mW, 75 V
- W0603: 100 mW, 75 V
- W0805: 250 mW, 100 V
- W1206: 333 mW, 200 V
- W1505: 350 mW, 100 V
- W2010: 800 mW, 175 V
- W2512: 1.0 W, 200 V
These resistors operate within a temperature range of -55°C to +150°C. They exhibit an Electrostatic Discharge (ESD) sensitivity between 2KV and 4KV, based on the Human Body Model (HBM). With a noise level of less than -25dB and a substrate made of 99.5% Alumina, these resistors ensure low noise and high stability for critical applications.
