Overview of HF353 by TE Connectivity
The HF353 signal relay is a Surface Mount Device (SMD) featuring a SPDT (Single Pole Double Throw) configuration, also known as 1 Form C. This type of relay is designed to switch between two circuits and is capable of handling up to 2A at 220VDC or 250VAC. It is part of the HF3 Series and offers a nominal coil voltage of 5VDC. The HF353 is characterized by a range of features that make it suitable for a variety of sophisticated switching applications: it has a coil resistance of 178 Ω, operates with a maximum coil voltage of 10.9 V, and requires a voltage of 3.75 V to operate successfully. Additionally, the contact surfaces are finished with gold, which provides reliable connectivity and durability.
This relay falls under the electronic parts subcategory of Other Relays. Importantly, the component is RoHS compliant, ensuring that it adheres to European standards restricting the use of hazardous substances in electronic and electrical equipment. Its design and construction comply with various international standards, including Reach, with a classification under ECCN EAR99 for export and an HTS code of 8536.49.00.50.
