Frequently Asked Questions
How many contacts does the TSM-124-03-FM-DH-P-TR provide and how are they arranged?
The TSM-124-03-FM-DH-P-TR provides 48 contacts arranged in a dual-row female socket configuration on a 0.100" (2.54 mm) pitch. This 24-per-row layout enables high pin-count board-to-board mating in a compact surface-mount footprint, suitable for industrial control, backplane, and embedded computing interconnect designs.
Why is the polarized housing important when the TSM-124-03-FM-DH-P-TR is used in a field-replaceable card application?
The polarized (P) housing on the TSM-124-03-FM-DH-P-TR incorporates a mechanical key that physically prevents reversed or misaligned mating of the 48-pin 0.100" (2.54 mm) dual-row socket. In field-replaceable card assemblies, this ensures technicians cannot reverse pin-1 orientation, protecting power rails, microcontroller I/O lines, and communication buses from damage during hot-swap or maintenance operations.
What current rating per contact should engineers use when routing power through the TSM-124-03-FM-DH-P-TR?
SAMTEC TSM-series contacts on 0.100" (2.54 mm) pitch are generally rated at up to 3 A per pin in free-air conditions at 25°C ambient. For a 48-pin TSM-124-03-FM-DH-P-TR carrying mixed signal and power, engineers should apply SAMTEC's thermal derating guidelines when enclosure temperatures exceed 25°C to keep contact and housing temperatures within safe limits.
Can the TSM-124-03-FM-DH-P-TR in tape-and-reel format be directly loaded into an IPC-compliant SMT production line?
Yes, the TR (tape-and-reel) suffix indicates the TSM-124-03-FM-DH-P-TR is packaged in industry-standard carrier tape compatible with IPC/JEDEC J-STD-033 compliant SMT pick-and-place equipment. This eliminates manual feeder loading, reduces placement cycle time, and supports lean production scheduling for runs involving hundreds or thousands of 48-pin connectors per shift.
