Overview
The TT Electronics Precision Thin Film Chip Resistors PFC Special Series datasheet provides detailed information on high precision and stable resistors suitable for commercial off-the-shelf (COTS) and military applications. These resistors offer an advantageous combination of reliability, precision, and resistance to harsh environments.
Product Features
These chip resistors come in standard sizes 0402, 0603, 0805, and 1206, with standard Sn/Pb and Pb-free terminations complying with RoHS requirements. The PFC series boasts an absolute Temperature Coefficient of Resistance (TCR) as low as ±10 ppm/°C, providing ultra-stable performance through a passivated Tantalum Nitride film. Specifically designed for environments with sulfur gases, these resistors are apt for automotive and heavy equipment applications where precision and robustness are critical.
Technical Attributes
The power rating varies by model, from 50mW for the W0402 to 333mW for the W1206, with respective maximum voltage ratings ranging from 75V to 200V. These resistors function reliably within a temperature range of -55°C to +150°C and possess low noise and high Electrostatic Discharge (ESD) immunity (between 2KV to 4KV). The resistors are mounted on a 99.5% Alumina substrate and feature wrap-around terminations with leach-resistant nickel barriers, ensuring dependable solder connections.
Performance and Reliability
The PFC Special Series demonstrates impressive environmental resilience, with performance stability within ±0.02% to ±0.10% under various test conditions, including sulfur exposure, thermal shock, and moisture resistance as per MIL-PRF-55342 standards. These resistors can be especially tailored for military use, undergoing further screening and marked accordingly.
Physical Specifications
The datasheet gives the dimensions of each resistor size, including length, width, and height, as well as the footprint (top, bottom, and side views) to aid in the design and integration process.
Manufacturing and Ordering Information
With meticulous manufacturing processes, the resistance range for these chip resistors spans from 50 ohms to 1 megohm, depending on the model, with tight tolerance levels from ±0.02% to ±0.1%. The datasheet includes a Power Derating Curve to provide guidance on power usage relative to ambient temperature.
Additional Information
TT Electronics notes that specifications are subject to change without notice, and this datasheet is accurate at the time of printing. For specific Pb-free or different value requirements, separate datasheets are recommended. Contact and ordering information are provided, emphasizing a comprehensive and continuously updated offering through the TT Electronics website.
