Product Specifications
These specifications provide a useful starting point for evaluating the KGM05 Series in applications such as low-voltage power rail filtering, IC decoupling, compact PCB designs, and high-density modules. In practical applications, designers should also evaluate factors including DC bias characteristics, effective capacitance, ripple current, operating temperature, PCB layout, and reliability testing requirements to ensure the component is suitable for the target application.
Typical Applications
1. AI Servers and AI Accelerators
AI servers, GPU boards, AI accelerator cards, and high-speed networking equipment place increasingly demanding requirements on power integrity. During operation, high-performance processors experience rapid load transients, requiring sufficient local decoupling to minimize transient voltage drops and ripple noise on the power rails.
The KGM05 Series is well suited for low-voltage power rail filtering, local IC decoupling, and high-density PCB layouts, enabling designers to increase capacitance density within limited board space. For high-temperature operating environments, the X6S variant provides additional thermal margin for board-level designs.
2. Smartphones and Edge AI Devices
AI smartphones, wearables, true wireless earbuds (TWS), and AIoT devices are highly constrained by available board space. Cameras, RF antennas, batteries, sensors, speakers, microphones, wireless connectivity modules, and AI processors all compete for space on the PCB.
The 0402 47 μF high-capacitance MLCC helps reduce the number of capacitors connected in parallel, freeing valuable PCB space to support more compact, thinner, and highly integrated product designs.
3. 5G Communication Modules and Edge Computing Devices
5G communication modules, industrial gateways, edge computing devices, and intelligent controllers often integrate processors, RF circuits, power management, and interface protection circuitry onto compact PCBs. High-capacitance, miniaturized MLCCs are well suited for power output filtering, local decoupling, and module-level power stabilization, helping improve overall system reliability.
4. New Energy Vehicles and Industrial Electronics
Low-voltage control systems in new energy vehicles (NEVs), battery management systems (BMS), in-vehicle communication modules, industrial control boards, energy storage systems, and other high-temperature operating environments place increasingly demanding requirements on MLCC reliability and stability. The X6S variant of the KGM05 Series provides an additional option for filtering and decoupling applications in elevated-temperature environments.
5. High-Density Consumer Electronics and Portable Devices
In tablets, laptops, smart audio devices, portable energy storage systems, compact robots, and other high-density consumer electronics, engineers must balance limited PCB space with cost constraints. High-capacitance, miniaturized MLCCs help improve power stability without significantly increasing board area, while also reducing the number of capacitors required in parallel.
From a Customer’s Perspective: MLCC Selection is also BOM Risk Management
As the MLCC market becomes increasingly segmented, component selection can no longer be based solely on unit price. Instead, customers should evaluate MLCCs from both a system design and supply chain risk management perspective.
When selecting high-capacitance MLCCs, customers should consider the following:
Can the number of capacitors connected in parallel be reduced, therefore saving PCB space?
Will it improve power supply stability and reduce design validation and debugging risks?
Does it provide the temperature characteristics and reliability required for the target application?
How significantly does DC bias affect effective capacitance, and has sufficient design margin been incorporated?
Is the product available through authorized distribution channels with a reliable long-term supply?
Are qualified alternative part numbers and lifecycle management plans available?
Should critical components be secured before further price increases occur?
For customers developing AI servers, new energy vehicles (NEVs), industrial automation equipment, and high-end intelligent devices, MLCCs are no longer merely supporting components. They have become critical components that influence product development schedules, production stability, and supply chain resilience.
