Littelfuse Single Pole Reed Relay SPST-NO, 5V dc, SIL Package

The Littelfuse Single Pole Reed Relay is a dependable switching component encased within a compact, single-in-line (SIL) epoxy-moulded package. Designed for precise control in low-power circuits, this normally open (SPST-NO) relay offers reliable performance and is protected by an integrated diode.

Its slim profile is a significant advantage, allowing for high-density PCB layouts and enabling mounting on centres as tight as 0.2 inches. This makes it an ideal choice for space-constrained applications where efficient use of board real estate is critical.
