The B11B-ZR-SM4-TFT(LF)(SN) is an 11-position crimp-style connector header manufactured by JST (Japan Solderless Terminal) Sales America Inc. It is part of the ZR series, specifically designed for surface mount (SMT) wire-to-board connections in compact electronic devices. The (LF)(SN) designation indicates that the connector is lead-free and has a tin plating finish.

Applications:

• Compact Electronic Devices: Used in small electronic devices requiring high-density wire-to-board connections.
• Industrial Control Equipment: Employed in control panels and machinery for signal and power connections.
• Consumer Electronics: Found in products like digital cameras, smartphones, and portable audio players.
• Medical Devices: Integrated into medical equipment where space is limited.
• Networking Equipment: Used in routers, switches, and other networking devices for signal transmission.

Features:

• 11 Positions: Accommodates eleven individual wires for connection.
• Crimp Style: Requires crimping tools to securely attach wires to the connector contacts.
• Surface Mount (SMT): Designed for mounting directly onto the surface of a printed circuit board (PCB).
• ZR Series: Part of JST's ZR series, known for its compact size and reliable performance.
• Lead-Free: Compliant with RoHS (Restriction of Hazardous Substances) directives.
• Tin Plating: Provides good solderability and corrosion resistance.

Benefits:

• High-Density Connection: Allows for a large number of connections in a small space.
• Reliable Connection: Ensures a secure and stable electrical connection between wires and the PCB.
• Compact Size: Saves valuable space on the PCB.
• Easy Assembly: Simplifies the manufacturing process through SMT assembly.
• RoHS Compliant: Meets environmental regulations for hazardous substances.

Additional Details:

The B11B-ZR-SM4-TFT(LF)(SN) is typically constructed from high-temperature resistant plastic materials suitable for reflow soldering processes, with tin-plated brass or copper alloy contacts. Key specifications include voltage and current ratings, wire gauge compatibility, and operating temperature range. Mating connectors and crimping tools are essential for proper assembly. Designers should consult the manufacturer's datasheet for detailed dimensions, PCB layout recommendations, and recommended crimping procedures to ensure a secure and reliable SMT connection.
