Product details

1.00 mm pitch SMT header for SH/SR receptacles

The SM03B-SRSS-TB: This is a 3-position, single-row header from JST's SH/SR series, designed to mate with the SH/SR crimp-style receptacle housings. The 1.00 mm pitch sets the board footprint and the per-contact current ceiling — at 1 A the temperature rise stays within the UL94 V-0 nylon housing limit. The header is shrouded on all four walls, which protects the male pins during mating and prevents misalignment with the receptacle.

Tin-plated contacts and operating envelope

Tin plating is cost-effective for moderate mating cycles — expect several dozen matings before contact resistance begins to rise. For higher cycle counts, the gold-plated variants in the SH/SR family are a better fit. Rated at 1 A per contact and 50 V, this header suits low-power signal and sensor connections inside equipment enclosures.

Frequently asked questions

What is the pitch of JST SM03B-SRSS-TB?

The pitch is 1.00 mm (0.039 inches), measured centre-to-centre on the single row of pins.

Is JST SM03B-SRSS-TB compatible with JST SH series connectors?

Yes, this header is part of the SH/SR series and mates directly with JST SH-series receptacle housings and crimp terminals.
