PFC-D1206-03-1000-1100-FD Description

The PFC-D1206-03-1000-1100-FD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 3-pin, 1206 concave SMD component features two resistors with values of 100Ω and 110Ω, offering tight 1% tolerance and a low ±25ppm/°C temperature coefficient for stable performance across a wide -55°C to +150°C range. 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 precision circuits. Packaged in tape and reel (T/R), it is optimized for automated assembly processes.

PFC-D1206-03-1000-1100-FD Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent stability compared to thick-film alternatives.
• Dual-Resistor Network: Integrates 100Ω and 110Ω resistors in a compact 1206 (3.2mm x 1.6mm x 0.61mm) footprint, saving PCB space.
• High-Temperature Performance: Operates reliably up to 150°C with derated power handling up to 70–150°C.
• Concave Termination: Ensures robust solder joint integrity and mechanical stability in high-vibration environments.
• Low TCR (±25ppm/°C): Minimizes resistance drift under thermal stress, critical for precision analog and signal conditioning circuits.
• Automation-Friendly: Supplied in tape and reel for efficient pick-and-place assembly.

PFC-D1206-03-1000-1100-FD Applications

• Voltage Dividers: Ideal for VOLT/D (voltage divider) circuits in sensor interfaces, ADC reference networks, and power monitoring systems.
• Precision Instrumentation: Used in medical devices, test equipment, and industrial controls where stability and accuracy are paramount.
• Consumer Electronics: Suitable for compact designs in audio equipment, wearables, and IoT devices requiring space-efficient resistor networks.
• Automotive & Aerospace (Non-Automotive Grade): Despite not being PPAP or automotive-qualified, it serves in non-safety-critical auxiliary systems with moderate environmental demands.

Conclusion of PFC-D1206-03-1000-1100-FD

The PFC-D1206-03-1000-1100-FD excels in applications demanding high precision, thermal stability, and space savings. Its thin-film construction, dual-resistor integration, and concave termination make it a superior choice over generic thick-film networks. While not RoHS-compliant, it remains a robust solution for industrial, consumer, and instrumentation designs where performance outweighs regulatory constraints. Engineers will appreciate its repeatable performance in voltage division, impedance matching, and signal conditioning scenarios.
