PFC-D1206-03-91R0-1802-FD Description

The PFC-D1206-03-91R0-1802-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 integrates two resistors with values of 91Ω and 18kΩ, offering a 1% tolerance and a low ±25ppm/°C temperature coefficient for stable performance across a wide operating range (-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 compact, high-density circuits. Packaged in tape and reel (T/R), it suits automated assembly processes.

PFC-D1206-03-91R0-1802-FD Features

• Precision Thin Film Technology: Delivers superior accuracy (±1%) and low TCR (±25ppm/°C) for stable resistance under thermal stress.
• Dual-Resistor Network: Combines 91Ω and 18kΩ in a single 1206 footprint, saving board space versus discrete resistors.
• High Power Density: 0.25W total dissipation (0.125W per resistor) at 70–150°C derated range, ideal for power-sensitive designs.
• Robust Construction: Concave termination style enhances solder joint reliability, while 100V rating ensures durability in high-voltage applications.
• Non-Automotive, Non-PPAP: Optimized for industrial/commercial use where PPAP compliance isn’t required.

PFC-D1206-03-91R0-1802-FD Applications

• Voltage Dividers (VOLT/D): Precision ratio matching in sensor interfaces or ADC reference circuits.
• Signal Conditioning: Biasing and attenuation in RF/analog systems (e.g., op-amp feedback networks).
• Power Management: Current limiting or load sharing in DC-DC converters.
• Consumer Electronics: Space-constrained PCBs in smart devices, where miniaturization and stability are critical.
• Industrial Controls: Stable performance in PLCs or measurement equipment exposed to temperature fluctuations.
