In the evolving landscape of smart metering, where space efficiency and reliable performance are paramount, Hongda’s HDLB series multilayer chip large current beads stand out as ideal solutions. Designed to suppress noise while handling high currents in compact enclosures, these components redefine efficiency for smart metering applications.
Smart meters demand miniaturized components to fit densely packed PCBs without compromising functionality. The HDLB series offers a range of ultra-compact sizes, with standout options for space-constrained designs:
1005 [0402]: Dimensions as small as 1.00×0.50×0.50mm (L×W×T) – perfect for the tiniest meter modules, freeing up space for additional sensors.
1608 [0603]: 1.60×0.80×0.80mm – balances size and power, ideal for mid-range smart meters needing a compact footprint.
These sizes eliminate the trade-off between miniaturization and performance, ensuring seamless integration into slim, modern meter designs.
Beyond size, the HDLB series delivers critical performance metrics tailored to smart metering’s demands:
High Rated Current (Ir): Handles large currents (up to 6000mA) to support continuous data transmission and power management in meters.
Low DC Resistance (RDC): Minimizes power loss (as low as 0.025Ω), enhancing energy efficiency – a core requirement for metering accuracy.
Wide Temperature Range: Operates reliably from -55℃ to +125℃, withstanding harsh outdoor or industrial environments.
