Series Datasheet

1MA Series
Shielded Power Inductor– Low DCR Type
Accetek A
FEATURES
Shielded Construction with very low DCR
Heating Current rating up to 17.9 Amps
Saturation Current rating up to 27.5 Amps (based on only 10% inductance drop)
Inductance up to 1mH for all case size (129 size up to 2.2mH)
260°C reflow peak temperature qualified
Operating Temperature range from -40°C to +125°C (Including Self-heating)
Protect tube inside to protect the enameled cooper wire
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 129 size (12.5×12.5×10.0mm) to meet with higher current requirements
 Available for both Metal Base and Plastic Base:
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
