JST SHD Series Straight Surface PCB Header, 20 Contacts, 1 mm Pitch, 2 Row, Shrouded BM20B-SRDS-G-TF(LF)(SN)

JST BM20B-SRDS-G-TF(LF)(SN) is a straight surface mount PCB header from the SHD series, featuring 20 contacts arranged in 2 rows with a precise 1 mm pitch. It is a shrouded, male connector designed for wire-to-board applications, delivering a reliable electrical interface in compact electronic assemblies.

The contacts are phosphor bronze plated with gold, providing superior conductivity and corrosion resistance, essential for maintaining signal integrity over time. The housing utilizes polyamide material, enabling operation within a broad temperature range from -25°C to 85°C, which suits varied industrial and commercial environments.

This product supports a voltage rating of 50 volts AC/DC and a current rating of 1 ampere, making it ideal for low-power electronic circuitry. The initial contact resistance is limited to 20 milliohms maximum, ensuring minimal contact loss and efficient power transmission.

The SHD series headers are designed with features like ribs and grooves that prevent incorrect insertion and help protect the connector during repeated mating cycles. The surface mount termination allows for automated PCB assembly, compatible with vacuum pick-and-place machines, thus enhancing manufacturing efficiency.

Manufactured in Korea, the BM20B-SRDS-G-TF(LF)(SN) complies with RoHS standards, assuring the use of environmentally safe materials. The header features a compact 1.0 mm pitch and a double-row configuration for high-density PCB layouts.

Contacts are made from phosphor bronze material plated with gold to provide excellent conductivity and corrosion resistance. The housing is constructed from durable polyamide, suitable for a wide operating temperature range from -25°C to 85°C.

Designed with a shrouded male contact system to prevent incorrect insertion and ensure secure mating. The surface mount type supports automated assembly and is compatible with vacuum pick-and-place equipment. Rated for a voltage of 50 V AC/DC and a current carrying capacity of 1 A, suitable for low voltage electronic applications.
