Overview of the PFC Series Precision Thin Film Chip Resistors
The PFC Series Precision Thin Film Chip Resistors Datasheet provided by 1i electronics IRC Advanced Film Division details the specifications and features of their precision resistors designed for various applications, including commercial off-the-shelf (COTS) and military uses. The resistors come in a variety of sizes, including 0402, 0603, 0805, 1206, 1505, 2010, and 2512 chip sizes, and are equipped with either standard 60/40 Sn/Pb or Pb-free (RoHS compliant) terminations. These chip resistors cater to applications demanding high precision and stability.
Key Features
The PFC Series is built around an ultra-stable Tantalum Nitride resistor film system with a passivated layer that ensures long-term life stability and environmental resistance. The durability of the resistive film and materials selected for these chip resistors ensures they maintain precision even under harsh surface mount soldering conditions. These resistors have a wrap-around termination featuring a non-leaching Nickel barrier for robust solder connections.
Electrical Data and Options
Electrical characteristics cover a broad range of power ratings, from 50mW for the W0402 model to 1W for the W2512 model. The maximum operating voltage ranges from 75V to 200V, depending on the resistor model. Operating temperature for the chip resistors spans from -55°C to +150°C, and the resistors exhibit low noise <-25dB, with Electrostatic Discharge (ESD) sensitivity ranging from 2KV to 4KV (Human Body Model). Additionally, the resistor substrate is comprised of 99.5% Alumina, ensuring quality and consistency.
Manufacturing Capabilities and Tolerance Options
The chip resistors come in a selection of tolerances, from ±5% to an ultra-precise ±0.02%, catering to various degrees of accuracy required in different applications. The Temperature Coefficient of Resistance (TCR) options are equally diverse, ranging from ±50 ppm/°C to ±10 ppm/°C, and even down to ±25 ppm/°C for some models, ensuring minimal resistance change with temperature fluctuations.
Resistance Range and TCR Variants
Different models within the PFC Series offer various resistance ranges, starting from 5Ω up to 1MΩ, depending on the specific model. TCR variants are also provided to best suit the intended environment and performance specifications of the end-use application.
