Precision Thin Film Chip Resistors – PFC Series

Category: Electronics, Resistors, TT Electronics PLC

Overview

The document is a datasheet for the PFC Series Precision Thin Film Chip Resistors offered by the IRC Advanced Film Division of nj electronics. The resistors feature an ultra-stable Tantalum Nitride resistor film system and are designed for both standard 60/40 Sn/Pb and Pb-free (RoHS compliant) applications. The series includes a range of sizes: 0402, 0603, 0805, 1206, 1505, 2010, and 2512. Additionally, these resistors are tested for Commercial Off-The-Shelf (COTS) applications and offer absolute Temperature Coefficient of Resistance (TCR) to ±10 ppm/°C, with military screening options available.

Features and Benefits

The PFC chip resistors are noted for their high precision and stability, due to the passivated Tantalum Nitride film, which ensures long-term life and environmental resilience. Specially selected materials and processing methods maintain initial precision, even under harsh surface mount soldering conditions. The resistors also include wrap-around terminations with a non-leaching Nickel barrier to ensure durable solder connections.

Electrical Specifications

The PFC Series encompasses various models with different electrical characteristics. The power rating ranges from 50mW for the smallest W0402 size up to 1.0W for the largest W2512 size. The maximum voltage rating also varies, starting at 75V for the smaller models and increasing to 200V for the larger ones.

Power Rating and Maximum Voltage

For instance, W0402 has a power rating of 50mW and a maximum voltage of 75V, while W2512 offers a power rating of 1.0W and a maximum voltage of 200V. Temperature ranges for these components are from -55°C to +150°C.

Additional Parameters

All models have a termination finish option of either 60/40 Sn/Pb or 100% tin that is RoHS compliant, plated over a nickel barrier. They are rated for Electrostatic Discharge (ESD) sensitivity from 2KV to 4KV, based on the Human Body Model (HBM). The substrate for these thin-film resistors is made from 99.5% Alumina, contributing to their noise specifications of less than -25dB.
