JZC-33F Subminiature Power Relay

The JZC-33F Subminiature Power Relay is a compact general-purpose PCB relay designed for switching electrical loads in electronic and industrial control applications. The series is available with different coil voltages and contact configurations, so the complete suffix should be checked before selecting a replacement.

For the standard coil version, available coil voltages include 3V, 5V, 6V, 9V, 12V, 18V, 24V, and 48V DC. The standard coil power is 0.45W, while sensitive versions use 0.2W and are available only with the SPST-NO configuration. For example, the standard 12V version has approximately 320Ω coil resistance, a 9V pickup voltage, and a 0.60V dropout voltage.

The JZC-33F offers 1 Form A (SPST-NO) and 1 Form C (SPDT) contact arrangements. Depending on the configuration, contact ratings can reach 5A at 250VAC/30VDC and 10A at 125VAC for the NO contact. The maximum switching voltage is specified up to 277VAC/30VDC, while the maximum switching current is up to 10A for the 1A/1C configurations.

The relay uses a PCB termination and has a compact standard PC-board layout. The relay body is approximately 20.5mm × 10.6mm × 15.3mm, with a weight of around 7g. Sealed versions are also available, with some variants specified as IP67.

The JZC-33F is suitable for industrial control panels, automation systems, power supplies, electronic equipment, PCB switching circuits, appliances, and general-purpose electrical control applications. It can also be used for replacement and repair work when the coil voltage, contact arrangement, contact rating, and pin layout match the original relay.
