Overview of the F250 Relay Nonlatch 2 PDT, 2 Amp Engineering Data Sheet

The datasheet presents detailed information on the non-latching, non-polarized, hermetically sealed F250 relay with 2 form C (2 PDT) contact arrangement, operating with direct current and designed to meet MIL-PRF-39016/6 performance standards. The document provides technical specifications, including contacts rated for 2 Amps at 28 Vdc and principal characteristics of the relay, which is suitable for various resistive, inductive, and lamp loads over extensive operation cycles.

Applicable Sockets and Dimensions

Compatible with the HRCW SQ9005 SF250R4 socket, the relay is encapsulated in a metallic can design for corrosion protection, indicating its robust construct. With dimensions listed as 20.6mm x 10.4mm x 10.5mm and a weight below 11 grams, the F250 relay is designed for compact and lightweight applications.

Technical Characteristics

The relay’s electrical performance is tabulated based on load type and operation cycles, which reflects the contact rating per pole for both 28Vdc and 115Vac at varying frequencies. According to the datasheet, the relay can handle resistive loads up to 2 Amps, 0.75 Amps for an inductive load, and 0.3 Amps for a lamp load.

Coil Characteristics

Coil specifications include data points for nominal operating voltages, coil resistance at +25°C, maximum operating voltage, pickup voltages at 25°C and 125°C, and minimum and maximum dropout voltages at various temperatures. This is vital for ensuring proper operation within different voltage and temperature extents.
