JST S2B-PH-K-S(LF)(SN)

Product FAQ

• 1. What are the primary electrical and mechanical specifications of the JST S2B-PH-K-S connector?
  The JST S2B-PH-K-S is a 2-position, 2.0mm pitch, through-hole shrouded header in the JST PH connector series. It features a PCB retention mechanism for secure board placement during assembly. The connector is rated for 2A AC/DC (AWG #24) and 100V AC/DC, with an operating temperature range of -25°C to +85°C (including temperature rise during current flow). It is designed for use with 0.8–1.6mm thick printed circuit boards and is RoHS compliant.
• 2. Which mating components are compatible with the JST S2B-PH-K-S?
  The S2B-PH-K-S is part of the JST PH connector series and mates with the PHR-2 housing and compatible PH-series crimp terminals, including SPH-002T-P0.5S, SPH-002T-P0.5L, and SPH-004T-P0.5S. Depending on the terminal used, the applicable wire size ranges from AWG #32 to #24.
• 3. How does the JST S2B-PH-K-S support reliable electrical performance?
  The S2B-PH-K-S is specified with an initial contact resistance of 10mΩ maximum, increasing to 20mΩ maximum after environmental testing. It also provides an insulation resistance of 1,000MΩ minimum and a withstanding voltage of 800V AC for one minute. These specifications support reliable operation when the connector is used within its rated electrical and environmental conditions.
• 4. What PCB considerations apply to the JST S2B-PH-K-S?
  The S2B-PH-K-S is a 2.0mm pitch through-hole shrouded header with a PCB retention mechanism. It is intended for use with 0.8–1.6mm thick printed circuit boards. JST notes that PCB hole dimensions may vary depending on the board material and manufacturing method, and the recommended dimensions in the datasheet should be used as a guideline.
• 5. Why is the JST S2B-PH-K-S commonly used for PCB connections?
  The S2B-PH-K-S is part of the JST PH connector series, which features a compact 2.0mm pitch, a fully shrouded header, and a PCB retention mechanism. According to JST, the series is designed for high-density connection of internal wires to printed circuit boards while providing a compact, highly reliable, and low-cost connector solution.
