The PFC Series by IRC Advanced Film Division specializes in Precision Thin Film Chip Resistors with a focus on high precision and stability. This series caters to commercial-off-the-shelf (COTS) applications and is available with both standard 60/40 Sn/Pb and Pb-free, RoHS-compliant terminations. Comprising various sizes, the PFC Series includes 0402, 0603, 0805, 1206, 1505, 2010, and 2512 chip sizes that are backed by the robustness of a Tantalum Nitride resistor film system.
The resistors are recognized for their ultra-stable performance and longevity, even under harsh environmental conditions. Key features such as a non-leaching nickel barrier and wrap-around termination ensure the high integrity of solder connections during surface mount assembly. The products are designed to maintain initial precision post-soldering, translating to reliable long-term performance.
Electrical and Mechanical Specifications
The electrical data for each chip size encapsulates power and voltage ratings which change with size: the smallest W0402 can handle 50mW and 75V, scaling up to the W2512 at 1.0W and 200V. All resistors maintain stable operation in temperatures ranging from -55°C to +150°C and boast ESD immunity ranging from 2KV to 4KV.
Performance in terms of noise is rated at less than -25dB, with components being soldered onto a 99.5% Alumina substrate. This contributes to their overall resilience and consistent performance.
Manufacturing Capabilities and Options
The PFC Series exhibits a wide tolerance range from ±5% to an ultra-precise ±0.02%, accommodating various design needs. Resistors are available in resistance ranges from 30Ω to 1.0MΩ across the different sizes, while temperature coefficient of resistance (TCR) options include ±25, ±50, or ±100 ppm/°C. Some models offer even tighter TCR values down to ±10 ppm/°C, illustrating the series’ adaptability for precision-critical applications.
