Ultraminiature reed relays are some of the smallest in the industry at less than 8mm. Their small footprint make them ideal in high stacking matrices. Furthermore, these ultraminiature reed relays come in a variety of package designs and mounting options. Our CRR and CRF series reed relays are some of the smallest (SMD) surface mount reed relays in the industry, at only 3.4 mm high. So their highly suitable for very low profile environments and automatic pick and place. Additionally, these small reed relays classify as instrumentation grade.
