YLRY-2010 SERIES
The YLRY-2010 series alloy chip resistors offer precise current sensing with low resistance (2–100mΩ) and stable ±50ppm TCR, suitable for automotive and industrial control systems. Available in 1W and 1.5W ratings with both standard and big terminal options.
Designed with electron-beam welded construction, these 2010-size resistors ensure high reliability and excellent thermal performance. They support tight tolerances from ±0.5% to ±5%, making them ideal for power management and sensing applications.
Featuring a big terminal version (YLRY10-K) for very low resistance (2–3mΩ), this series enhances current carrying capacity and solder joint reliability. Suitable for motor drives, battery monitoring, and compact power modules where space and performance are critical.
These resistors operate across a wide temperature range from -55°C to 170°C, meeting automotive-grade environmental requirements. Offered in tape-and-reel packaging, they support automated assembly for high-volume manufacturing.
With its compact 2010 footprint and robust performance, the YLRY series is ideal for modern electronic designs requiring reliable current detection in limited space, such as consumer electronics, IoT devices, and industrial automation systems.
