PFC-D1206-03-4702-3000-DD Description

The PFC-D1206-03-4702-3000-DD from TT Electronics/IRC is a high-precision thin-film resistor network designed for surface-mount applications. This 3-pin, 1206 concave SMD component features two resistors with values of 47KΩ and 300Ω, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±25ppm/°C for stable performance across a wide operating temperature range (70°C to 150°C). With a maximum voltage rating of 100V and a total power rating of 0.25W (1/4W), it is ideal for high-density PCB designs requiring reliable signal conditioning or voltage division. Packaged in tape and reel (T/R), it supports automated assembly processes.

PFC-D1206-03-4702-3000-DD Features

• Precision Thin Film Technology: Delivers superior accuracy (±0.5%) and low TCR (±25ppm/°C) for stable resistance under thermal stress.
• Dual-Resistor Network: Combines 47KΩ and 300Ω in a compact 1206 (3.2mm x 1.6mm x 0.61mm) footprint, saving board space.
• High Power Handling: 0.125W per resistor (0.25W total) with derating up to 150°C, ensuring reliability in demanding environments.
• Concave Termination: Enhances solder joint integrity and mitigates tombstoning during reflow.
• Automation-Ready Packaging: Supplied in tape and reel for efficient pick-and-place assembly.
• Non-Automotive/Non-PPAP: Suitable for industrial, telecom, and consumer electronics where PPAP compliance is not required.

PFC-D1206-03-4702-3000-DD Applications

• Voltage Dividers: Precision ratio matching for sensor interfaces or ADC reference circuits.
• Signal Conditioning: Stable attenuation in audio, instrumentation, or communication systems.
• Power Management: Current limiting or feedback networks in DC-DC converters.
• Industrial Controls: Robust performance in PLCs, motor drives, or test equipment.
• Consumer Electronics: Space-constrained designs like wearables or IoT devices.

Conclusion of PFC-D1206-03-4702-3000-DD

The PFC-D1206-03-4702-3000-DD excels in applications demanding precision, compactness, and thermal stability. Its thin-film construction, dual-resistor integration, and concave termination make it a standout choice over thicker-film or less stable alternatives. While not RoHS-compliant, it remains a cost-effective solution for non-regulated markets. Engineers will appreciate its balance of performance, size, and manufacturability, particularly in high-reliability industrial or telecom systems.
