What are the key features of TSM-102-04-LM-DV-P?
- 4-position dual-row layout at 0.100" (2.54 mm) pitch offers universal compatibility with standard breadboard and perfboard footprints for rapid prototyping and production
- Surface-mount termination with low-profile mounting enables automated SMT reflow assembly and eliminates through-hole drilling requirements
- Dual-voltage (DV) contact rating supports mixed-signal PCB layouts combining both low-voltage digital and higher-voltage analog or power signals on a single 4-pin header
What is TSM-102-04-LM-DV-P used for?
The TSM-102-04-LM-DV-P is suitable for compact 4-pin SMT signal headers on embedded microcontroller boards, sensor breakout modules, and prototype development platforms where a standard 0.100" pitch dual-row connector is required. Its surface-mount form factor and low profile make it ideal for consumer electronics, IoT devices, and industrial control cards that undergo automated reflow soldering without requiring through-hole vias. The dual-voltage contact rating also accommodates 4-pin power and signal interfaces in mixed-voltage designs such as motor driver auxiliary connectors and relay control headers.

Frequently Asked Questions
What does the dual-row, 4-position configuration of TSM-102-04-LM-DV-P mean in terms of total pin count and footprint?
The TSM-102-04-LM-DV-P is a dual-row connector with 4 positions total, meaning 2 pins per row arranged in a 2x2 grid at 0.100" (2.54 mm) pitch. The overall footprint is approximately 5.08 mm x 2.54 mm, fitting the universal 0.100" grid used across standard breadboards, Arduino shields, and prototype PCBs. This compact 4-pin dual-row layout supports 4 independent signal or power lines within the smallest standard header footprint.
How does the TSM-102-04-LM-DV-P surface-mount design simplify PCB manufacturing compared to through-hole alternatives?
The TSM-102-04-LM-DV-P uses a surface-mount termination that eliminates the need to drill 4 through-holes in the PCB, reducing fabrication cost and time on multi-layer boards where via drilling constrains routing layers. The low-profile SMT mounting is compatible with standard solder paste and reflow oven processes, enabling the connector to be placed alongside 0402, 0603, and QFN components on the same assembly pass. This reduces assembly cost per board in production volumes of 100 or more units.
Which embedded or IoT development platforms most commonly use the 0.100" pitch 4-pin dual-row header format of TSM-102-04-LM-DV-P?
The 0.100" (2.54 mm) pitch 4-pin dual-row header format of the TSM-102-04-LM-DV-P is used extensively on Arduino Uno, STM32 Nucleo, and Raspberry Pi expansion headers, as well as on I2C and SPI breakout boards that use a 4-pin VCC/GND/SCL/SDA or VCC/GND/MOSI/MISO configuration. The 2x2 pin layout at 2.54 mm pitch is also the standard for JTAG debug connectors on many ARM Cortex-M development boards, making the TSM-102-04-LM-DV-P a versatile header choice for firmware development and production IoT hardware.
