Hirose DF33C Series Straight Through Hole PCB Header, 8 Contacts, 3.3 mm Pitch, 2 Row, Shrouded DF33C

Hirose DF33C Series is a compact and robust straight through hole PCB header connector featuring 8 male contacts spaced at a 3.3 mm pitch across 2 rows within a shrouded polyamide housing. This connector is designed primarily for wire-to-board applications requiring dependable power connections with a current rating of 5A, suited for 20 AWG wire.

The shrouded housing is constructed with a glass-filled resin to minimize thermal shrinkage and prevent solder joint cracking, enhancing assembly reliability. It features a strong positive locking mechanism that produces a tactile click upon full engagement to prevent accidental disconnect due to vibration or external shocks. Inside, the contacts are individually boxed with internal walls, preventing electrical short circuits and improving safety.

Guide posts on the connector facilitate accurate placement and orientation on the printed circuit board during manufacturing, streamlining assembly processes. This header supports resin sealing up to 6.5 mm above the PCB surface to provide resistance against dust and moisture, extending durability in harsh industrial environments.

Operational temperature ranges from -35°C to 85°C, adequately supporting applications in LED lighting, office equipment, medical devices, robotics, smart meters, and various home and industrial appliances. Contact material is brass with tin plating to ensure excellent conductivity and corrosion resistance. The connector’s design meets the required 1.5 mm creepage distances as stipulated by electrical safety regulations and is Glow Wire compliant for flame resistance.

This DF33C connector is a vital component for efficient, safe, and space-saving internal power supply connections, representing the advanced EnerBee brand’s philosophy of combining superior performance within compact form factors.
