What are the key features of WK73S2B15TTD6R49D?
- Wide-terminal construction in 1206 package (3.2 mm × 1.6 mm × 0.6 mm) enables superior solder joint reliability and thermal dissipation
- 6.49 Ω resistance value with tight ±0.1% tolerance supports precision current sensing and voltage-divider networks
- Surface-mount tape-and-reel (7-inch) packaging compatible with high-speed automated pick-and-place assembly lines
What is WK73S2B15TTD6R49D used for?
The WK73S2B15TTD6R49D is well-suited for precision current sensing in power management circuits, motor driver feedback networks, and industrial control boards where accurate 6.49 Ω low-value resistance is required. Its wide-terminal 1206 SMT footprint improves solder joint area and mechanical robustness, making it reliable in vibration-prone environments such as automotive and factory automation systems. The JESD-609 e3 lead-free compliant construction satisfies RoHS requirements for consumer electronics and green-manufacturing programs.

Frequently Asked Questions
What resistance value and tolerance does the WK73S2B15TTD6R49D offer for precision sensing circuits?
The WK73S2B15TTD6R49D provides a 6.49 Ω resistance value with a tight ±0.1% tolerance, making it suitable for high-accuracy current sensing and voltage divider applications where deviation greater than 6.5 mΩ would cause measurement error.
How does the wide-terminal construction of the WK73S2B15TTD6R49D improve board-level reliability?
The wide-terminal design extends the solder land area compared to standard chip resistors in the same 1206 package (3.2 mm × 1.6 mm), reducing solder fatigue under thermal cycling from -55°C to +155°C and improving mechanical pull strength on the PCB.
What packaging format does the WK73S2B15TTD6R49D use, and how does that affect procurement lead times?
The WK73S2B15TTD6R49D ships in 7-inch punched paper tape-and-reel packaging, which is compatible with standard automated assembly equipment. Reel quantities typically contain 5,000 units, simplifying high-volume procurement planning and reducing per-unit handling cost on production lines.
