Key Features
- 18 positions in dual-row 0.100" pitch layout enabling compact signal routing
- Flush-mount (FM) profile keeps connector body nearly level with the PCB surface for height-critical designs
- Kinked tails (K) improve solder joint stability during reflow across all 18 positions
- Tape-and-reel (TR) packaging for seamless integration into automated pick-and-place assembly lines
Applications
The TSM-109-04-FM-DH-A-K-TR is ideal for embedded systems, RF front-end boards, and sensor interface modules where board height clearance is critical and 18-position dual-row signal connectivity is required. Its flush-mount design allows mating connectors or overlying PCBs to sit extremely close to the board surface. The kinked tail SMT construction ensures mechanical stability through lead-free reflow soldering profiles.

Frequently Asked Questions
What is the function of the FM suffix in TSM-109-04-FM-DH-A-K-TR?
The FM suffix indicates a Flush-Mount housing style, where the connector body sits nearly at PCB surface level with a mounted height typically under 3 mm. This makes the 18-position TSM-109-04-FM-DH-A-K-TR suitable for ultra-low-profile designs such as wearable electronics, compact embedded modules, and multi-layer PCB stacks with minimal inter-board spacing.
How does the 0.100" pitch of TSM-109-04-FM-DH-A-K-TR compare to fine-pitch alternatives?
The 0.100" (2.54 mm) pitch is a standard grid spacing widely supported by PCB design tools and mating connectors, simplifying routing compared to 0.050" or 0.040" fine-pitch alternatives. For 18 positions in a dual-row layout, this pitch strikes a balance between signal density and ease of PCB layout, hand soldering, and visual inspection.
Which industrial applications commonly use the TSM-109-04-FM-DH-A-K-TR?
Common applications include industrial sensor interfaces, process control I/O boards, and motor driver gate signal distribution requiring 18-channel dual-row connectivity at 0.100" pitch. The connector handles signal voltages up to 125 V AC/DC and is compatible with operating temperatures from -55°C to +125°C, covering harsh factory automation environments.
Does the tape-and-reel packaging affect the minimum order quantity for TSM-109-04-FM-DH-A-K-TR?
Tape-and-reel (TR) packaged connectors are typically supplied in reels of 500 to 2,000 pieces depending on part size, with minimum order quantities often at 1 reel. For the 18-position TSM-109-04-FM-DH-A-K-TR, distributors commonly stock cut-tape quantities as low as 10 pieces for prototyping alongside full-reel quantities for production procurement.
