Precision Thin Film Nichrome Chip Resistor PCF Series Overview

The PCF Series produced by T electronics’ IRC Advanced Film Division is a family of precision thin film nichrome chip resistors designed for a range of applications requiring high precision and reliability. These resistors offer a tight temperature coefficient of resistance (TCR) down to ±5 ppm/°C and tolerances as accurate as +0.1%. They are available in six standard sizes and feature a broad ohmic value range from 10Ω to 2.0MΩ. Standard tin/lead (Sn/Pb) and lead-free terminations are available to suit various assembly requirements.

Product Features and Specifications

The PCF Series resistors have multiple features that make them suitable for high-precision applications:

Wide ohmic range supporting values from 10Ω to 2.0MΩ.
Availability in standard EIA sizes: 0201, 0402, 0603, 0805, 1206, and 1210.
TCR options ranging from ±5 ppm/°C to ±50 ppm/°C based on resistor size.
Max Power ratings at 70°C range from 50 to 250 milliwatts depending on the size.
Maximum working voltage and overload voltage that also vary with size, up to 400 volts for the PCF1210 model.
Standard packaging on paper or plastic carrier reels in quantities of 5,000 or 10,000 pieces.

Environmental performance tests, such as short time overload, temperature cycling, humidity, load life, high and low-temperature exposure, effects of solder heat, and solderability, are listed with respective maximum percentage changes in resistance. The precision resistors demonstrate excellence in stability, defined by changes as minimal as ±0.1% to ±0.25% after various stress tests complying with MIL-STD-883 and MIL-STD-202 methods.

Physical Dimensions and Environmental Compliance

Each resistor size in the PCF Series is detailed with precise dimensional attributes (width, height, and length). Notably, the smallest PCF0201 model measures just 0.024 inches in width, while the largest PCF1210 stretches to 0.126 inches wide. Furthermore, IRC highlights a general note that it reserves the right to make specification changes at any time without notice or liability, following their internal data deemed accurate at the time of print.
