News Release | New Product: Metal Composite Type ‘XRJ0420 Series’
February 11, 2026
Sagami Elec Co., Ltd. is pleased to announce the development of the metal composite power inductor ‘XRJ0420 Series’ (W4.1 mm × D4.1 mm × H2.0 mm), with sample now available.
This product expands our metal composite power inductor lineup XRJ Series with a compact 4mm size design. The XRJ0420 Series offers a wide inductance range from 0.56 μH to 4.7 μH, is AEC-Q200 compliant, and features reduced DCR with optimized allowable current balance for each inductance value. As a result, the series achieves higher rated current performance than conventional products, making it well suited for applications requiring increased current capacity.
In addition to a wide range of power module applications, the XRJ0420 Series is also ideal for audio-visual equipment and applications exposed to harsh temperature environments, benefiting from stable DC bias characteristics with minimal variation due to changes in ambient temperature.
