The MRPR-20 Reed Switch is a miniature, normally open switch with a 20.32mm long x 2.84mm diameter (0.800" x 0.112") glass envelope, capable of high voltage and power switching of 265Vac at 50VA. The MRPR-20 has high insulation resistance of 1010 ohms minimum and contact resistance less than 100 milli-ohms.

The multiport MC line protector is an integrated, multichip solution for protecting multiple twisted pair from overvoltage conditions. It is intended for applications sensitive to load values. Typically, high speed connections require lower capacitance. CO values for the MC devices are 40% lower than standard UC devices. Based on a six-pin surface mount SOIC package, it is equivalent to four discrete DO-214AA or two TO-220 packages, which makes it ideal for densely populated, highspeed line cards that cannot afford PCB inefficiencies or the use of series power resistors. Surge current ratings up to 500A are available. SIDACtor® devices are used to enable equipment to meet various regulatory requirements including GR 1089,ITU K.20, K.21, and K.45, IEC 60950, UL 60950, and TIA-968 (formerly known as FCC Part 68).Notes: All measurements are made at an ambient temperature of 25°C. Ipp applies to -40°C through +85°C temperature range. Ipp is a repetitive surge rating and is guaranteed for the life of the product. Listed SIDACtor® devices are bi-directional. All electrical parameters and surge ratings apply to forward and reverse polarities. Vdrm is measured at Idrm. Off-state capacitance is measured between pins 1-2 and 3-2 at 1MHz with a 2V bias and is a typical value.

Littelfuse MS Series external mount Microswitches offer permanent blown fuse indication to PSR Series High-Speed Square-Body Semiconductor Fuses. They have one normally open (N.O.) and one normally closed (N.C.) contact rated for 4A, 250Vac. These microswitches have a visual red flap or arm indicator that releases after fuse blown condition and can also be used for resetting the microswitch contacts.

The MSM replaces bi-metal type timing with reliable solid-state circuitry. There are no moving parts to arc or wear. It is a cost effective solution for OEM designers. It is available for printed circuit board mounting or surface mounting with a removable bracket and wire leads. The MSM offers immediate reset on removal of power. Operation (Delay-on-Make) The time delay begins upon application of input voltage. The output is de-energized before and during the time delay. At the end of the time delay, the output energizes and remains energized until input voltage is removed.Reset: Removing input voltage resets the time delay and output.
