HF33F-005-HSLTF Miniature Intermediate Power Relay 5VDC 5A PCB SPST-NO

The HF33F-005-HSLTF relay from Hongfa is a compact miniature intermediate power relay designed for low to medium load switching in PCB-based electronic and control systems. It features a Form 1A (SPST-NO) contact configuration, making it suitable for simple on/off switching in compact circuits where reliability and space efficiency are important.

This relay operates with a 5VDC coil rated at 55 , allowing direct compatibility with low-voltage control logic, microcontrollers, and embedded systems. Its coil design provides efficient actuation with moderate power consumption, ensuring stable switching performance in tightly integrated electronic designs.

With a maximum switching capacity of 5A at 250VAC, the HF33F-005-HSLTF is intended for light-duty power control applications such as small motors, signal switching, lighting circuits, control modules, and appliance logic interfaces. It is well-suited for designs where moderate current handling is required without the size and cost of larger power relays.

The relay features a plastic-sealed construction that helps protect internal components from dust and environmental contamination, improving long-term reliability. It also provides 8mm creepage distance and 1kV isolation voltage, supporting safe operation in low to medium voltage control systems.
