3R3 Flat Wire Surface Mount Inductor Wholesale
This high-current SMD power inductor features a manganese-zinc ferrite core and flat-wire windings, thereby achieving exceptional saturation current and temperature-rise current characteristics. In addition, this high-current SMD inductor features a three-pad terminal design, providing better mounting stability and vibration resistance on the circuit board. All raw materials comply with RoHS and REACH regulations, and the product has a humidity sensitivity rating of 1 (MSL). Its maximum operating temperature is +125°C. Thanks to these attributes, this high-current inductor serves as an ideal choice for harsh environments or various high-current power supply applications.
We offer custom-designed high-current flat-wire inductors. For inquiries, please contact us at info@smdinductor.com. Zhenhua Company provides inventory information, product quotations, and technical specifications for flat-wire inductors and offers wholesale pricing.
