Frequently Asked Questions
What distinguishes the FM contact style of TSM-139-03-FM-DV-P-TR from the TM variant (TSM-139-03-TM-DV-P-TR)?
The FM designation in TSM-139-03-FM-DV-P-TR indicates a female socket contact style with recessed contacts, while TM denotes a through-mount or male-style termination. The FM female contact mates with a corresponding male pin header from SAMTEC's TSM or SHF series at 0.100 inch (2.54 mm) pitch, providing a secure mating interface for repeated insertion and removal cycles in modular 78-position dual-row designs.
How many pins per row does TSM-139-03-FM-DV-P-TR provide and what bus widths does it support?
TSM-139-03-FM-DV-P-TR has 78 total positions arranged across 2 rows, with 39 pins per row on a 0.100 inch (2.54 mm) pitch. This accommodates wide parallel data bus interfaces such as 32-bit or 36-bit buses with additional control signals, making it suitable for FPGA I/O expansion boards, industrial PLC modules, and backplane signal distribution in embedded computing systems.
What does the DV (dual-voltage) designation mean for power and signal routing in TSM-139-03-FM-DV-P-TR?
The DV designation in TSM-139-03-FM-DV-P-TR indicates the connector is optimized to carry both low-voltage signal lines and higher-voltage power rails within the same 78-position housing. This allows PCB designers to route 3.3 V and 5 V signals alongside 12 V or 24 V power pins on a single connector, reducing PCB real estate and connector count in industrial control and power distribution board designs.
Is TSM-139-03-FM-DV-P-TR suitable for high-volume automated SMT production and what does the TR suffix confirm?
Yes. The TR suffix confirms TSM-139-03-FM-DV-P-TR is supplied in tape-and-reel format with the surface-mount termination style required for automated pick-and-place equipment. The connector withstands reflow soldering at up to 260°C peak temperature per IPC J-STD-020, enabling integration into standard lead-free SMT assembly lines processing thousands of boards per shift.
What current per contact can TSM-139-03-FM-DV-P-TR carry for power distribution across its 78 positions?
SAMTEC TSM series connectors on 0.100 inch (2.54 mm) pitch typically support 1 A per contact at standard operating conditions up to 105°C ambient. Across 78 positions, designers can parallel multiple pins to deliver higher currents — for example, assigning 10 pins in parallel provides approximately 10 A capacity for a shared power rail, while the remaining 68 pins carry signal and return connections.
