Precision Thin Film Chip Resistors – PFC Series

The PFC Series by nj electronics IRC Advanced Film Division encompasses a range of precision thin film chip resistors designed for various applications. These resistors are notable for their high precision and stability, provided by the ultra-stable Tantalum Nitride resistor film system. The series includes different sizes, such as 0402, 0603, 0805, 1206, 1505, 2010, and 2512 chips, catering to different requirements in electronic designs.

Key Features

The resistors are known for their performance and long-term life stability, even in harsh environments. They come with various termination options, including standard 60/40 Sn/Pb and Pb-free (RoHS compliant) terminations, ensuring compatibility with different assembly processes. The resistors are also characterized by non-leaching nickel barriers, wrap-around terminations, and absolute Temperature Coefficient of Resistance (TCR) to ±10ppm/°C.

Applications

The resistors are tested for Commercial Off-The-Shelf (COTS) applications, and MIL screening is available for more stringent requirements.

Electrical Data

Electrical specifications vary depending on the model, with power ratings from 50mW to 1.0W and maximum voltage ratings from 75V to 200V. The operating temperature range for these chip resistors spans from -55°C to +150°C, ensuring their reliability across a broad range of environmental conditions. The datasheet also mentions that the resistors exhibit Electrostatic Discharge (ESD) sensitivity of 2KV to 4KV based on the Human Body Model (HBM), and have a noise level below -25dB.

Termination and Substrate

Termination options include the choice between 60/40 Sn/Pb or 100% tin (RoHS compliant) plated over a nickel barrier. Substrates are made of 99.5% Alumina, contributing to the component’s robustness.

Manufacturing and Quality

IRC uses specially chosen materials and manufacturing processes to ensure the resistors retain their precision even after facing extreme surface mount soldering environments. The commitment to quality is also demonstrated through the implementation of a non-leaching nickel barrier and wrap-around termination, which contribute to the durability and quality of the solder connections.
