Frequently Asked Questions
What is the pin count and pitch of the TSM-121-02-H-DH-A-K-TR?
The TSM-121-02-H-DH-A-K-TR has 42 positions arranged in a dual-row layout on a 2.54 mm (0.100 inch) pitch, giving 21 pins per row. This standard pitch ensures compatibility with common through-hole and SMT footprints used in embedded computing and industrial designs.
What current and voltage ratings apply to the TSM-121-02-H-DH-A-K-TR contacts?
Each gold-plated contact in the TSM-121-02-H-DH-A-K-TR is rated at 3 A continuous current and 250 V AC working voltage. These ratings make the connector suitable for mixed signal-and-power applications on industrial control and communications boards without risk of thermal or dielectric stress.
How does the high-profile (H) variant of this SAMTEC TSM series connector differ from standard-profile versions?
The high-profile (H) variant provides a taller body height above the PCB, typically around 8.38 mm, compared to the low-profile version. This extra clearance allows stacked boards to maintain a defined air gap of at least 5 mm for thermal management and cable routing in 2-board sandwich assemblies.
