• A stress-reducing soft resin layer beneath the resistor that minimises solder crack formation during thermal cycling
• A smooth alumina substrate surface that ensures uniform resistive film thickness
• A long, fine serpentine resistance pattern that disperses current load concentration, providing industry-leading electrostatic discharge (ESD) resistance. The ERA-8PEB1004V demonstrates these capabilities with specifications suited to datacenter power monitoring: • A high limiting element voltage of 500 V at 1 MΩ for monitoring high-voltage power rails
• A 0.25 W power rating that ensures minimal power loss • A wide operating temperature range of -55°C to +155°C • A superior electrostatic discharge (ESD) resistance for reliable operation in high-power environments
Using Wi-Fi to monitor power efficiency DCIM faces growing complexity as AI workloads drive the deployment of more servers, storage systems and power supply units. While monitoring power consumption across these systems is crucial for optimising efficiency, traditional wired monitoring solutions add cost, complexity and cable- management challenges that only compound as facilities scale. Wireless monitoring offers an elegant solution to these
challenges. It enables real-time power management through voltage, current and temperature measurements without the overhead of additional cabling. This approach provides greater flexibility for scaling operations up or down without reconfiguring the physical connections. However, wireless modules for data centre applications must
address several stringent requirements: • Maintain reliable connectivity in environments with numerous obstacles and potential interference sources
• Minimise power consumption to maintain overall efficiency gains
• Fit within compact form factors to integrate with existing equipment
• Provide robust security features to protect sensitive data centre information

The Panasonic ENW-49A01A3EF PAN9320 Wi-Fi module
(Figure 5) addresses these challenges through its comprehensive feature set: • 2.4 GHz operation provides superior penetration through data centre obstacles while ensuring broad compatibility through support for 802.11b/g/n standards.
• Power efficiency is maintained through a minimum transmit (Tx) power consumption of 430 milliamperes (mA) for transmit (Tx) and 160 mA for receive (Rx) in 802.11b mode.
• A compact 29.0 mm × 13.5 mm × 2.66 mm surface-mount design simplifies integration.
• Built-in security features, such as TLS/SSL, HTTPS, and WPA2, protect sensitive information. T ese capabilities enable data centre operators to implement
comprehensive power monitoring while minimising the physical and operational overhead typically associated with such systems.
Conclusion The demands of AI workloads require a rethink of their power infrastructure, from individual component selection to facility- wide monitoring systems. Panasonic’s portfolio of hybrid capacitors, ultra-low ESR technology, precision resistors and wireless connectivity provides datacenter operators with the tools they need to build and maintain efficient, scalable power systems to support next-generation AI applications.
