Precision Thin Film Chip Resistors – PFC Series Overview

The PFC Series Chip Resistors from IRC Advanced Film Division are designed to offer high precision and ultra-stable performance using a Tantalum Nitride resistive film system. They are available in various chip sizes, including 0402, 0603, 0805, 1206, 1505, 2010, and 2512. These resistors are suited for commercial off-the-shelf (COTS) applications and offer an absolute Temperature Coefficient of Resistance (TCR) up to ±10ppm/°C. Options for Military screening are also provided.

Key Features:

The PFC Series boasts the following features:

Stable Performance: The TaNFilm® ensures long-term stability and resistance to environmental factors.
Durable Terminations: Wrap-around terminations with non-leaching nickel barriers facilitate robust solder connections.
Compliance: Standard 60/40 Sn/Pb and Pb-free terminations comply with RoHS standards.

Electrical Data

The electrical properties depend on the model size, with power ratings ranging from 50mW to 1.0W and voltage ratings from 75V to 200V. Additionally, the resistors have ESD ratings of 2KV to 4KV and operate within a temperature range of -55°C to +150°C.

Manufacturing Capabilities and Resistance Range

IRC’s manufacturing capabilities allow for multiple tolerance options including ±5%, ±2%, ±1%, ±0.5%, ±0.1%, ±0.05%, and ±0.02%. Resistance ranges vary with chip size, extending up to 3.3MΩ for smaller chips and up to 1.0Ω for larger chips. The TCR options available include ±100ppm/°C, ±50ppm/°C, ±25ppm/°C, ±15ppm/°C, and ±10ppm/°C allowing for precise temperature compensation.

Applications and Quality Assurance

These resistors are ideal for precision applications requiring long-term stability and reliability. IRC’s commitment to quality is highlighted by their reservation of rights to modify product specifications, ensuring that all information is current and accurate at the time of printing.
