HFD4/3-SR Description

Short technical summary and product information.

The Hongfa HFD4/3-SR is a general-purpose relay categorized under Signal Relays, Up to 2 Amps. This component features a DPDT (Double Pole Double Throw) contact form and a non-latching coil type, operating with a 3V coil voltage. It is rated for a contact current of 2A and can switch up to 250VAC or 220VDC.

 

The relay is designed for surface-mount technology (SMT) applications, offering a compact solution for various electronic designs. Its telecom relay type designation suggests suitability for telecommunication equipment and related signal processing circuits.

 

This model is manufactured by Hongfa and is part of their General Purpose Relays product line. The SMT package facilitates automated assembly processes, making it efficient for high-volume production.

 

Key specifications include a 3V coil, DPDT contacts, 2A current rating, and a maximum switching voltage of 250VAC/220VDC. The non-latching coil ensures that the relay's state is determined by the presence or absence of coil voltage.
