JST B2B-PH-K-S(LF)(SN)

Product FAQ

• 1. What are the electrical ratings and physical dimensions of the JST B2B-PH-K-S(LF)(SN) connector?
  The JST B2B-PH-K-S(LF)(SN) is a 2-position, through-hole shrouded header in the JST PH Series with a 2.0 mm pitch. It is rated for 2 A AC/DC when used with AWG #24 wire and supports a maximum operating voltage of 100 V AC/DC. The connector measures approximately 4.5 mm in width and 8.0 mm in mounted height, making it suitable for high-density PCB connections. The wafer is manufactured from PA66 (UL94V-0) flame-retardant material and is supplied in accordance with JST's RoHS-compliant PH Series specifications.
• 2. What housings and crimp terminals are used with the B2B-PH-K-S(LF)(SN)?
  The B2B-PH-K-S(LF)(SN) is part of JST's PH connector system, which uses PHR-series receptacle housings (e.g., PHR-2 for a 2-position mate) together with PH Series crimp terminals. Compatible terminals include SPH-002T-P0.5S, which supports AWG #30 to AWG #24 wire, along with SPH-002T-P0.5L (AWG #28–24) and SPH-004T-P0.5S (AWG #32–28) for smaller wire gauges. Contact JST to confirm the exact housing/terminal pairing for your application.
• 3. What are the key electrical performance specifications of the JST PH Series connector?
  The JST PH Series connector has an initial contact resistance of 10 mΩ maximum, increasing to 20 mΩ maximum after environmental testing. It provides an insulation resistance of at least 1,000 MΩ and a withstanding voltage of 800 VAC for one minute. The specified operating temperature range is −25°C to +85°C, including temperature rise caused by current loading.
• 4. What PCB specifications are recommended for the B2B-PH-K-S(LF)(SN)?
  The B2B-PH-K-S(LF)(SN) is a through-hole connector with a 2.0 mm pin pitch. The JST PH Series specification recommends use with printed circuit board thicknesses from 0.8 mm to 1.6 mm. PCB hole dimensions should follow the dimensions shown in the JST drawing, with JST noting that hole size may vary depending on PCB material and manufacturing method.
• 5. What applications is the JST B2B-PH-K-S(LF)(SN) designed for?
  The JST B2B-PH-K-S(LF)(SN) is designed for high-density connection of internal wires to printed circuit boards. As part of the JST PH Series, it offers a compact 2.0 mm pitch, a low-profile design measuring approximately 8.0 mm in mounted height, and a fully shrouded header for reliable wire-to-board connections in space-constrained electronic equipment.
