As consumer electronics, automotive electronics, and communication equipment move towards miniaturisation and high power density, engineers face increasingly prominent challenges in achieving greater current capacity and lower power loss within limited PCB space. Traditional wire-wound inductors are relatively bulky and struggle to meet compact design requirements. Molded Inductors provide a flexible power inductor solution for this.
Scenario 1: DC-DC Converters – Balancing Low Profile and High Current
DC-DC converters are widely used in various electronic devices, responsible for converting input voltage into a stable output voltage. As devices become smaller, converter power density continues to increase, placing higher demands on the inductor's current carrying capability and package height.
Core Challenges
- Limited PCB space requires low-profile inductors (some applications require <2mm)
- High current demand – traditional inductors struggle to balance high current with low loss
- High-frequency switching generates EMI, requiring magnetically shielded designs
Suitability of Molded Inductors
- LPM series offers minimum heights as low as 1.0mm (LPM0110, LPM2510C, etc.), suitable for compact designs
- LPM1250C series supports currents up to 50A, meeting the needs of high-power DC-DC converters
- Magnetically shielded design reduces EMI interference, suitable for high-density PCB layouts
- Low DCR reduces conduction loss and improves conversion efficiency
Scenario 2: Automotive Electronic Systems – Wide-Temperature Operation and High Reliability
The operating environment for automotive electronic systems (such as ECUs, BMS, and infotainment systems) is harsh, with wide temperature variations and extremely high requirements for long-term component reliability.
Core Challenges
- Wide operating temperature range (-55°C to +125°C)
- Vibration and shock environments place high demands on mechanical strength
- Long-term operation imposes strict requirements on component lifespan and consistency
Suitability of Molded Inductors
- Operating temperature range of -55°C to +125°C, covering the harsh environments of automotive electronics
- Molded structure provides excellent mechanical strength, resistant to vibration and shock
- High-reliability design, suitable for long-term continuous operation
- RoHS compliant, meeting the environmental requirements of the automotive industry
Scenario 3: Communication Equipment and Network Systems – Low EMI and Stable Performance
Communication equipment and network systems have strict requirements for power supply stability and electromagnetic compatibility. EMI generated by power inductors can interfere with communication signals and affect data transmission quality.
Core Challenges
- EMI generated by power inductors can interfere with communication signals
- Communication equipment requires long-term stable operation
- High-density PCB layouts impose size constraints on inductors
Suitability of Molded Inductors
- Magnetically shielded design effectively suppresses EMI interference, safeguarding communication signal integrity
- LPM series compact size adapts to high-density communication equipment
- Wide operating temperature range ensures stable operation of outdoor communication equipment
- Low audible core noise, suitable for indoor communication equipment
Scenario 4: Computers and Peripherals – Compact Size and Low Noise
Computers and peripherals such as laptops, hard disk drives, and scanners have high requirements for inductor size and noise. Internal device space is compact, and users are sensitive to noise.
Core Challenges
- Compact internal space requires low-profile inductors
- Users are sensitive to noise, requiring low audible noise
- Battery-powered devices require high efficiency and low DCR
Suitability of Molded Inductors
- AISM series sizes range from 1008 (2.5×1.8×2.0mm) to 2220 (5.6×5.0×5.0mm) , adapting to different space requirements
- Low audible core noise improves user experience
- Low DCR design reduces power loss and extends battery life
- Molded structure provides excellent mechanical strength, adapting to the mobile environment of portable devices
