Reed Relays offer reliable switching

Littelfuse has expanded its reed relay product portfolio extending voltage capabilities to include AC ratings supporting AC or DC loads up to 300 Vdc, and providing input/output isolation voltage 2500 VRMS.

These miniature reed relays are available in single In-line (SIL) and dual-in-line (DIL) packages.

The relays offer:
  • Capable of switching speeds up to 1 kHz and billions of operations.
  • Hermetically sealed switch contacts are unaffected by and have no effect on their external environment.
  • Lower power coil consumption than competing electromechanical devices.
  • Very low circuit board space requirement due to miniature DIL and SIL packages.
  • No leakage in the off state, making them an ideal choice for battery-powered devices.

Reed relays provide a longer life, smaller size, higher switching speeds, and lower power consumption than electromechanical relay switches and are used for switching of loads with up to 2500 V isolation between the low-voltage control signal and load circuit.

Reed relays come in a hermitically sealed miniature package and offer full galvanic (zero leakage current) load disconnect that provides the high reliability needed in harsh environment applications to switch AC/DC signals and loads.
