Additional Details

The HF3FD/012-HSTF relay utilizes a 12VDC coil voltage. Its contact arrangement is typically 1 Form C (SPDT - Single Pole Double Throw). Contact ratings often include a maximum switching voltage of around 30VDC and a maximum switching current of approximately 1A. The insulation resistance between the coil and contacts is generally very high, exceeding 10^9 ohms. The operating temperature range usually spans from -40°C to +85°C. The 'HSTF' suffix likely indicates specific material or performance characteristics related to high sensitivity or temperature stability. This relay is designed to provide consistent and reliable switching in a wide range of applications where low-level signal integrity is crucial and a 12VDC control voltage is available.
