FTR-K1CK005W is an electromagnetic power relay with a 5V DC coil, designed to be soldered directly onto a PCB. Its single changeover contact, or SPDT, switches between two circuits. It is suitable for control circuits in appliances, lighting and automation equipment.
The contact rating is 16A / 250VAC or 16A / 24VDC for resistive loads. When switching motors, transformers or other inductive loads, use the corresponding datasheet limits rather than the 16A nominal rating alone. Above 10A, heat transferred from the PCB to the relay must also be considered.
The coil is rated at 400mW, corresponding to approximately 80mA at 5V. This is a standalone relay, not a ready-made control module. The manufacturer datasheet provides the connection diagram and PCB hole layout.
