Precision Thin Film Chip Resistors PFC Series Datasheet

Category: Electronics, Resistors, TT Electronics PLC

The PFC Series datasheet outlines the features and specifications of the IRC Advanced Film Division’s Precision Thin Film Chip Resistors. These resistors are available with both standard 60/40 Sn/Pb and Pb-free (RoHS compliant) terminations, and come in various chip sizes, specifically 0402, 0603, 0805, 1206, 1505, 2010, and 2512. The PFC Series has been tested for Commercial Off-The-Shelf (COTS) applications and offers an absolute Temperature Coefficient of Resistance (TCR) to ±10ppm/°C. For demanding applications, Military (MIL) screening is available, thus ensuring that the products can withstand stringent standards.

The series features an ultra-stable Tantalum Nitride resistor film system that assures consistent long-term performance. It employs a non-leaching Nickel barrier and a wrap-around termination design, which ensures firm solder connections and contributes to its robust environmental performance. Intended for high precision requirements, the PFC Series resistors are constructed using specially selected materials and manufacturing processes that maintain initial precision even in harsh surface mount soldering environments.

Electrical Data

The electrical characteristics of the PFC Series are broken down by model size. The power ratings range from 50mW for the smallest 0402 size up to 1.0W for the largest 2512 size. Maximum voltage ratings vary according to the resistor size, starting at 75V for the 0402 and 0603 models, and ranging up to 200V for the 1206 and 2512 models. The resistors are designed to operate within a temperature range of -55°C to +150°C and offer low noise levels of less than -25dB. Electrostatic Discharge (ESD) sensitivity for the series is between 2KV to 4KV using the Human Body Model (HBM). Furthermore, the resistors are constructed with a 99.5% Alumina substrate and employ either 60/40 Sn/Pb or 100% tin (RoHS compliant) for termination over the nickel barrier.
