DM3AT-SF-PEJM5(40) Description

Short technical summary and product information.

The Hirose DM3AT-SF-PEJM5(40) is a microSD™ card connector and ejector from the DM3 series, designed for reliable card insertion and retention in space-constrained applications. It features a push-push (push in, push out) ejection mechanism that ejects the card 4.0 mm for easy removal, along with built-in card fall-out prevention. The connector has 10 positions (8 + 2 with card detection) and a normally open card detection switch.

 

Electrical ratings include a maximum current of 0.5 A per contact and a maximum voltage of 125 V AC. Dielectric withstanding voltage is 500 V AC for 1 minute. Mechanical durability is rated for a minimum of 10,000 insertion/removal cycles. The operating temperature range is -25°C to +85°C, with storage from -40°C to +85°C.

 

The connector is surface mounted at a right angle with a height above board of 1.68 mm. Gold contact finish ensures reliable electrical connections. It is RoHS3 compliant, REACH unaffected, and has a Moisture Sensitivity Level (MSL) of 1, allowing unlimited floor life.
