Overview of IRC’s PFC Series Precision Thin Film Chip Resistors

IRC’s PFC Series resistors feature a Tantalum Nitride film system developed for reliability and precision across a range of surface-mount chip sizes. Offering stability and performance suitable for commercial-off-the-shelf (COTS) applications, these resistors have been tested rigorously for quality assurance. With options for both standard 60/40 Sn/Pb and Pb-free terminations, customers have the flexibility to select their preferred configuration compliant with RoHS standards.

Sizes and Features

The chip sizes available include the 0402, 0603, 0805, 1206, 1505, 2010, and 2512, covering a broad spectrum of requirements. An ultra-stable Tantalum Nitride resistor film system ensures extended stability and performance. A notable feature includes the non-leaching nickel barrier with wrap-around termination, promoting robust solder connections even under the most challenging conditions. All PFC series chips mirror the environmental stamina characteristic of IRC’s Military Series.

Electrical Specifications

The PFC Series resistors support various power ratings beginning from 50 mW for the W0402 model up to 1 W for the W2512. Equipped to handle maximum voltage ranges from 75V up to 200V, these resistors demonstrate versatile electrical capacity. The operating temperature range across the board spans from -55°C to +150°C, which is favorable for diverse industrial applications. IRC has also incorporated ESD protection between 2KV to 4KV Human Body Model (HBM), addressing concerns for electrostatic discharge vulnerability. The substrate used for these resistors is 99.5% pure alumina, known for high thermal conductivity and electrical insulation properties.

Resistance Range and Tolerances

The range of resistance options varies with each chip size, starting from as low as 30 ohms to up to 1.0 megaohms, depending on the model. In terms of tolerance levels and temperature coefficient of resistance (TCR), the PFC Series is designed to cater to the precise needs, with options down to ±0.02%. The series provides different TCR values from ±25 ppm/°C to ±100 ppm/°C, strongly suggesting its use in temperature-sensitive applications.

Manufacturing and Quality Assurance

Customers can have confidence in the reliability of IRC’s PFC Series, as it is produced using the same stringent processes as their Military Series components. IRC reserves the right to modify specifications at any time, ensuring continuous improvement and adaptation to technological advancements.

Overall, the PFC Series from IRC’s Advanced Film Division offers robust and precise resistor options for a wide range of industrial applications. The resistance precision and stable performance in harsh environmental conditions make them suitable for high-requirement electronic systems. With diverse sizing, resistance ranges, and tolerance levels, these resistors are tailored to meet exacting specifications for quality and performance.
