Shielded Power Inductor– Low DCR Type

Accetek Electronics (Shenzhen) Co., Ltd.                        www.accetek.com                                         Ver.:1MA‐2013A

Accetek 

 Shielded Construction with very low DCR

 Heating Current rating up to 17.9 Amps

 Saturation Current rating up to 27.5 Amps

 Inductance up to 1mH for all case size (129&159 size up to 2.2mH)

 260°C reflow peak temperature qualified

 Operating Temperature range from -40°C to +125°C (Including Self-heating)

 High strength sealing epoxy with stable temperatures character to keep the parts strong at wide range temperatures:

(Typical Hardness: ShoreD86 @25°C, ShoreD70 @125°C)

 Available up to 159 size (15.5×15.5×11.0mm) to meet with higher current requirements

 Available for both Metal Base and Plastic Base from 73 to 129 size:

Plastic Base: Because of the one piece construction and better adhesion so they are more suitable for high vibration or shock applications

Metal Base: For general use and more competitive cost than Plastic base
