1x1 vs. 2x1 Brick Form Factors: A Guide to Selecting Industrial DC-DC Converters for High-Density Designs

In the world of Industrial 4.0, the DC-DC converter is the heart of system stability. Whether you are designing for Industrial 5G, automated factory controllers, or harsh-environment power systems, the choice between the ultra-compact 1" x 1" and the standard 2" x 1" form factor is critical.

Beyond mere wattage, the Input Voltage Range and Thermal Resilience are the true differentiators for long-term reliability on the factory floor.

1. The Versatility of Wide Input: Solving Industrial Voltage Fluctuations

Industrial power rails are notoriously diverse and often accompanied by voltage spikes or dips.

• The 8:1 Strategic Edge (2x1 40W Series):

Our 2x1 40W module features a powerful 8:1 (9V-75V) input range. In an industrial context, this means a single module can handle 12V, 24V, and 48V systems simultaneously.

• The Benefit: It drastically simplifies procurement and inventory management (SKU reduction) and provides a robust buffer against transient voltage swings common in heavy-machinery environments.
• The 4:1 Efficiency Specialist (1x1 30W & 2x1 50W Series):

For systems with more defined power rails, the 4:1 input range offers optimized energy conversion. The 1x1 30W module, in particular, achieves high efficiency in a tiny footprint, minimizing heat generation—a vital feature for sealed, non-ventilated industrial enclosures.

3. Thermal Management in Harsh Environments

Industrial equipment often faces high ambient temperatures without the luxury of cooling fans. Our "Brick" series modules are engineered for these conditions:

1. Passive Cooling: The 2x1 50W (4:1) module provides a larger surface area for heat dissipation. This allows it to maintain full load in high-temperature factory settings without the risk of thermal shutdown.
2. Density Optimization: In space-constrained Industrial 5G modules or edge computing nodes, the 1x1 30W saves up to 50% of PCB real estate. This allows for more compact housing while maintaining industrial-grade isolation and noise immunity.

4. Precision Power for 5G & High-Frequency Signals

While these converters are built for general industrial use, they excel in Industrial 5G applications where signal integrity is paramount. We have optimized these modules with:

• Low Ripple & Noise: Crucial for preventing power-line interference with sensitive RF components.
• EMI Compliance: Designed to pass stringent industrial electromagnetic standards, ensuring stable 5G or Wi-Fi connectivity even near high-interference motor drives and inverters.

Conclusion: Which Module Fits Your Design?

• Choose the 2x1 40W (8:1) if you need Universal Compatibility. It is the ultimate "solve-all" for various industrial input voltages (12V/24V/48V).
• Choose the 1x1 30W (4:1) if you are focused on Miniaturization. It offers the best power-to-size ratio for compact industrial IoT devices.
• Choose the 2x1 50W (4:1) if you require Maximum Thermal Reliability. It provides the power and cooling headroom needed for high-load industrial 5G and networking nodes.
