PFC-D1206-03-1100-1102-FD Description

The PFC-D1206-03-1100-1102-FD from TT Electronics/IRC is a high-precision thin-film resistor network designed for surface-mount applications. This 3-pin 1206 concave SMD device integrates two resistors with values of 110Ω and 11kΩ, offering a 1% tolerance and a ±25ppm/°C temperature coefficient for stable performance across a wide operating temperature range of -55°C to +150°C. With a 0.25W (1/4W) total power rating (0.125W per resistor) and a 100V maximum voltage rating, it is engineered for reliability in demanding circuits. Packaged in tape and reel (T/R), it is optimized for automated assembly processes.

PFC-D1206-03-1100-1102-FD Features

• Precision Thin Film Technology: Delivers low noise, high stability, and tight tolerance (±1%) for critical analog and signal conditioning circuits.
• Dual-Resistor Network: Combines 110Ω and 11kΩ in a compact 1206 (3.2mm x 1.6mm x 0.61mm) footprint, saving PCB space.
• Wide Temperature Range: Operates from -55°C to +150°C, with derated power handling up to 150°C.
• Concave Termination: Enhances solder joint reliability and mitigates tombstoning in reflow processes.
• Non-Automotive (PPAP No): Ideal for industrial, telecom, and consumer electronics where automotive certification is not required.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded soldering.

PFC-D1206-03-1100-1102-FD Applications

This resistor network excels in:

• Voltage Divider Circuits: The 110Ω/11kΩ pair is optimized for precision voltage scaling in sensor interfaces and ADC front-ends.
• Signal Conditioning: Low TCR (±25ppm/°C) ensures minimal drift in instrumentation and measurement systems.
• Power Management: Robust 100V rating supports buffering and load sharing in DC-DC converters.
• Industrial Controls: Stable performance in harsh environments (e.g., PLCs, motor drives) due to its wide temperature range.
• Consumer Electronics: Compact size and reel packaging suit high-volume production of audio equipment, displays, and IoT devices.

Conclusion of PFC-D1206-03-1100-1102-FD

The PFC-D1206-03-1100-1102-FD stands out for its precision, space efficiency, and reliability, making it a superior choice for designers needing stable resistor networks in non-automotive applications. Its thin-film construction, concave terminations, and dual-resistor configuration address common challenges in PCB layout and thermal management. While not RoHS-compliant, it remains a versatile solution for legacy systems and industrial electronics where lead-free compliance is not critical. For engineers prioritizing accuracy and durability in compact designs, this model offers a compelling balance of performance and cost-effectiveness.
