Hirose DF33C Series Straight Through Hole PCB Header 4 Contacts 3.3 mm Pitch 2 Row Shrouded DF33C

Hirose DF33C Series Straight Through Hole PCB Header DF33C is a precision-engineered wire-to-board connector designed for reliable industrial and commercial electronic applications. Featuring 4 male brass contacts with tin plating, this 2 row, 3.3 mm pitch header is shrouded to provide robust protection and a secure mechanical lock.

The polyamide housing incorporates glass filled resin to minimize thermal shrinkage and eliminate solder joint cracking, ensuring long-term durability under demanding conditions. Its positive locking mechanism produces a tactile click, preventing accidental disconnection even under external mechanical shocks or vibration.

These headers support resin sealing up to 6.5 mm above the PCB surface, offering against ingress of dust and moisture. The internal partitions between contacts eliminate the possibility of short circuits by keeping each contact isolated. The connector is rated for a maximum current of 5A when paired with 20 AWG wire and withstands voltages up to 500V.

Operating temperature spans from -35°C to 85°C, making it suitable for varied ambient environments. Incorporating guide posts, it ensures accurate PCB placement and orientation during assembly. The connector also meets the 1.5 mm creepage distance requirements, complying with safety standards including the Electrical Appliance and Material Safety Act. While it does not carry other formal approvals, it is Glow Wire compliant.

Typical industrial use cases include compact internal power supplies, LED lighting installations, office and home appliances, medical equipment, robotics, industrial controllers, and smart metering solutions.
