Product details

Three-Position, One-Millimeter Pitch — Where This Header Fits

The SM03B-NSHSS-TB (LF)(SN): The right-angle SMT orientation keeps the mated wire parallel to the board surface — useful when z-height above the PCB is tight.

Board Layout and Termination Checklist

Right-angle orientation means the connector body overhangs the board edge by about 4.40 mm (the insulation height).

How the 3-Position Differs from the 4-Position Sibling

The only difference between SM03B-NSHSS-TB (LF)(SN) and SM04B-NSHSS-TB (LF)(SN) is the circuit count: 3 positions vs 4. Pitch, current rating, voltage, mounting orientation, shrouding, and latch type are identical. If your BOM calls for 4 positions, order the SM04B variant — no other spec changes.

Frequently asked questions

What is the mating connector for SM03B-NSHSS-TB (LF)(SN)?

The mating half is the JST NSH series crimp receptacle housing, which accepts the NSH crimp terminals. The header's latch holder engages the ramp on the receptacle housing for a positive lock. Confirm the housing part number includes the latch feature.
