Precision Thin Film Chip Resistors

Category: Electronics, Resistors, TT Electronics PLC

Overview

The PFC Series by IRC Advanced Film Division encompasses a range of Precision Thin Film Chip Resistors designed for high precision and stability. These resistors are constructed using the robust Tantalum Nitride resistor film system, providing superior performance. They are available for Commercial Off-The-Shelf (COTS) applications and offer military-grade screening options. These components are notable for their Absolute Temperature Coefficient of Resistance (TCR) reaching as low as ±10 ppm/°C.

Features

The series includes chip resistors in seven different sizes: 0402, 0603, 0805, 1206, 1505, 2010, and 2512. It boasts both standard 60/40 Sn/Pb and Pb-free (RoHS compliant) terminations ensuring environmental responsibility. A noteworthy feature is the non-leaching Nickel barrier, paired with wrap-around terminations, which strengthen the solder connections making them more reliable.

Applications

The resistors are suitable for high precision applications where long-term stability and reliable performance are mandatory. Given their robust build, using them in harsh surface mount soldering conditions is feasible.

Electrical Data

Temperature Range: These resistors can operate between -55°C to +150°C, ensuring functionality across a wide range of environmental conditions.
ESD Sensitivity: The range is designed to handle between 2KV to 4KV Human Body Model (HBM), indicating strong resistance to electrostatic discharges.
Noise: They feature low noise characteristics of less than -25dB, indicating minimal electronic disturbance.
Termination Substrate: The resistors are placed on a 99.5% pure Alumina substrate which plays a crucial role in their performance and durability.
