The B3B-ZR-SM4-K-TF(LF)(SN) is a 3-position, 1.5mm pitch, SMT right angle header from JST's ZR series of wire-to-board connectors. These connectors are designed for high-density mounting and provide reliable connections in compact electronic devices. The TF(LF)(SN) suffix indicates that the part is lead-free and suitable for reflow soldering processes. The “-K” indicates it ships in embossed tape for automatic placement.

Applications

• Consumer Electronics: Used in digital cameras, audio players, and other portable devices for connecting internal components.
• Industrial Equipment: Suitable for connecting PCBs in industrial control systems and automation equipment where a right-angle connection is needed.
• Medical Devices: Employed in medical instruments where space is limited and reliable right angle connections are crucial.
• Automotive Electronics: Used in automotive control units and sensor connections requiring a right angle.
• Office Automation Equipment: Connecting various boards within printers and copiers.

Features

• Compact Design: 1.5mm pitch enables high-density mounting on PCBs, saving valuable board space.
• SMT Compatibility: Designed for surface mount technology (SMT), facilitating automated assembly processes.
• Right Angle Configuration: Right angle configuration allows for connections perpendicular to the board, offering design flexibility.
• Secure Locking Mechanism: Provides a reliable connection, preventing accidental disconnections due to vibration or shock.
• Lead-Free: Compliant with RoHS standards, ensuring environmental friendliness and adherence to global regulations.

Benefits

• Space Savings: The small footprint allows for more components to be placed on the PCB.
• Automated Assembly: SMT compatibility reduces manual labor and increases production efficiency.
• Reliable Connection: Secure locking mechanism ensures stable electrical performance.
• Environmental Compliance: Lead-free construction meets environmental regulations and promotes sustainability.
• Design Flexibility: Right angle configuration offers more options for board layout.

Additional Details

The connector is made of high-temperature resistant materials, allowing it to withstand reflow soldering temperatures. The housing material is typically a UL94V-0 rated plastic, providing flame retardancy. The B3B-ZR-SM4-K-TF(LF)(SN) is designed to mate with JST's ZR series crimp style socket contacts. It is commonly used with discrete wires in the 26-30 AWG range. The current rating is typically around 1.0A per contact, and the voltage rating is around 50V AC/DC. Packaging typically comes in tape and reel for automated pick-and-place assembly.
