Introduction

The SIDELED™ SFH 4256B & SFH 4244B Infrared Emitters from ams OSRAM are advanced optoelectronic components designed for efficient and reliable infrared light emission. These side-emitting SMT (Surface-Mount Technology) LEDs are engineered to deliver high performance in a compact package, making them ideal for a wide range of modern electronic applications.

Part Description

The SFH 4256B and SFH 4244B are part of the SIDELED™ family, featuring integrated reflectors that enhance light output and uniformity. The SFH 4256B emits infrared light at a peak wavelength of 860nm, while the SFH 4244B operates at 950nm. Both models are designed for surface mounting, which simplifies integration into densely packed circuit boards. Their side-emitting design allows for more flexible placement and improved illumination in applications where space is limited. These emitters are AEC-Q102 qualified, ensuring high reliability for automotive and industrial environments. Key benefits include brighter images, increased lighting homogeneity, and reduced drive current, all contributing to lower power consumption and higher efficiency.
