BL 20 SMD 18

Headers, Receptacles, Female Sockets Overview

The BL 20 SMD 18 is an 18-position surface-mount header connector manufactured by Fischer Elektronik. It features a 2.54 mm (0.100 inch) pin pitch and gold-plated contacts for reliable signal transmission. The connector utilizes a PA 4.6 GF insulating body, rated for a nominal voltage of 150 V DC and a test voltage of 1500 V. It supports a temperature range from -40°C to +163°C and withstands soldering heat at 260°C for 10 seconds. Designed for precision surface-mount applications, it accommodates specific pin diameters and offers options for automatic assembly.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the exact suffix configuration against the datasheet, as variations such as 'SM' or 'TR' indicate specific plating or tape-and-reel packaging options. Confirm that the required pin diameter falls within the supported range of 0.65 mm to ensure proper mechanical fit. Check RoHS compliance status if environmental regulations apply to your specific project requirements.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a rigid, surface-mounted header with gold contacts is required for high-reliability connections. Ensure the PCB layout accommodates the 2.54 mm pitch and the physical dimensions of the 18-position housing. Consider the operating temperature range up to 163°C and the thermal endurance during soldering processes to guarantee long-term performance stability in the target application environment.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the BL 20 SMD series of connectors from Fischer Elektronik, which specializes in precision-engineered components for surface-mount technology.
