Additional Details

The KA4738-ALD series power inductors are available in various inductance values to suit different application requirements. The specific inductance value is denoted in the full part number. For example, a part number might be KA4738-ALD-XXXX, where XXXX represents the inductance value in microhenries (µH). Key electrical specifications include inductance, saturation current, DC resistance (DCR), and self-resonant frequency (SRF). These inductors are typically used in switching regulator circuits, where they store energy and smooth out voltage and current waveforms. The shielded construction is particularly important in applications where EMI must be minimized, such as automotive electronics and sensitive instrumentation. The operating temperature range is typically -40°C to +125°C. Coilcraft provides detailed datasheets with comprehensive performance characteristics and application notes to aid in the design process.
