Every milliohm you add to a high-current power path creates additional loss, but you still need enough sense voltage for reliable current feedback.

A low-ohmic metal alloy resistor gives designers options to manage that tradeoff while maintaining stable current sensing as operating temperatures change.

Meet the Bourns CRH2512 Series. Our new high power metal alloy resistor delivers low-ohmic current sensing in a compact 2512 surface mount package, ideal for industrial controllers, power supplies, digital meters, battery management systems, and other high-power applications.

To help designers manage current sensing and power loss, the CRH2512 Series offers:
• Resistance values from 0.5 mΩ to 30 mΩ
• Power rating up to 5W
• TCR of ±75 ppm/°C at 0.5 mΩ and ±50 ppm/°C from 1 mΩ to 30 mΩ
• ±1%, ±2% and ±5% tolerance options
• Operating temperature range of -55°C to +170°C

When selecting a shunt for an industrial controller, how do you balance sense voltage, I²R loss and temperature-driven measurement error?

B is for Bourns. B Inclusive.

Meet Ines Rodriguez, Product Compliance Engineer at Bourns de Mexico.

Ines started with Bourns in August 1996 as an operator on the production lines. Since then, she has worked in Quality, pursued her engineering education, and continued growing her career at Bourns.

Along the way, her journey has encouraged others to keep learning and building toward their own futures.

Today, Ines and her team help colleagues feel supported by answering questions, providing training, and guiding people toward the information they need.

For Ines, “B Inclusive” means helping others find their way forward.

How do you help others feel supported at work?

If your current measurements are drifting as a DC fast charger heats up, that error can carry through to charging control, power monitoring, and protection functions.

A four-terminal current sense resistor with tight tolerance and low TCR can help minimize measurement uncertainty and maintain stability as thermal conditions change.

The new Bourns SC2 Series Surface Mount Wirewound Resistor combines a four-terminal design with high-precision performance for current sensing and power applications, including DC fast chargers, battery formation and test equipment, pulse power systems, and industrial motor drives and inverters.

Key features include:
• Tolerances down to ±0.005%
• TCR down to ±5 ppm/°C
• Current capability up to 25 A
• -55°C to +275°C operating temperature range
• Superior surge-handling capability
• Optional non-inductive windings for high-frequency environments

How are you balancing current measurement accuracy, thermal drift, and shunt resistor power dissipation in next-gen DC fast charger designs?

As AI datacenter racks draw more power, the hot swap stage becomes a critical protection point in the rack power chain.

It limits inrush current during board insertion, but also needs protection from inductive kickback, upstream surge transients, and overvoltage events that can damage the controller or load.

In a new EETech article, Bourns’ Pedro Ramirez explains how coordinated component selection can help protect key hot swap functions, including:
• Inrush current sensing
• Overvoltage clamping for high-voltage rails
• Low-profile clamping options for tight layouts
• Bulk capacitor discharge

Read “Implementing Effective Hot Swap Protection for AI Datacenters” to learn how designers can support safer, more predictable hot swap operation in AI rack power designs: https://bourns.co/4jmkUbN

If you work on high-density rack designs, which hot swap protection strategies have been most effective in your experience?

The Bourns team is happy to introduce you to Deepak Sonawane, our new Sr. Software Developer/Architect for AI/RPA.

Deepak joins Bourns with extensive experience in AI, automation, and enterprise architecture, along with a passion for turning emerging technologies into scalable digital solutions.

“I’m excited to be part of a company with such a strong legacy of engineering excellence,” Deepak says. “I look forward to leveraging AI and automation to create impactful solutions and contribute to Bourns' continued innovation journey.”

Welcome to the Bourns team, Deepak! We’re excited to see the impact you will make.

As RF frequencies climb, inductor losses can make it harder to maintain the selectivity and tuning accuracy your circuit needs.

A high-Q air coil inductor with a high self-resonant frequency can help reduce losses and maintain predictable performance in high-frequency tuning and signal conditioning circuits.

Introducing the new ACXX57SQ Series Air Coil Inductors from Bourns. This series gives designers a surface mount solution for high-frequency television and radio receivers, radio transmitters, RF amplifiers, and tuning applications.

Key features include:
• Typical Q value of 140
• Minimum self-resonant frequencies from 0.72 GHz to 1.15 GHz
• 90 nH to 300 nH inductance range
• ±2% and ±5% tolerance options
• Maximum rated current from 3.7 A to 5.7 A
• Flat top and bottom surfaces for mechanical stability and automated pick-and-place assembly

When selecting inductors for RF tuning networks, how do you balance higher Q performance against footprint constraints and target operating frequency?

B is for Bourns. B Engaged.

As a Product Line Manager, Karla Lopez knows how important it is to B Engaged. In fact, she sees customer relationships and outcomes as a key element for staying invested in her work.

When asked what keeps her connected to the bigger picture, Karla said: “the customer and the positive impact we can bring to their operations. The goal is seeking to become a true partner invested in their success by adding our strengths to theirs!”

That philosophy is also baked into how she approaches challenges. For example, when a customer faced an assurance of supply concern, Karla and the team worked with stakeholders to better understand the issue.

Through dedicated technical discussions and asking the right questions, they identified an alternate material validation path that could help keep supply moving and prevent a shortage. That’s what it means to B Engaged!

How do you stay engaged with the bigger picture of your work?

You need reliable rotary position feedback, but integrating the sensor around a larger shaft can complicate your mechanical design.
