SMD Power Inductors (TPULF7032/7045)
Unshielded SMD Power Inductors Cut Down On Resistance. DeMint produces a wide and varied range of surface mount inductors that are ideal for all portable applications. Other application areas include: telecommunications, consumer and industrial electronics. In order to handle high rated current, SMD inductors must have a low ohmic resistance and minimal losses at high frequencies. DeMint (TPULF7032/7045) surface mount unshielded series are designed for high-current with lowest DCR wire-wound inductors.
With a footprint of 7.4 x 7.4 mm, the (TPULF7032) version has an insertion height of 3.5 mm. Available inductance values for the new (TPULF7032) are from 1.00 uH to 100.00 uH with rated current up to 2.88A. With inductance values from 1.00 uH to 1000.00 uH, the (TPULF7045) has a rated current up to 2.8A. Thanks to its temperature stability, it can be used in ambient temperatures ranging from -40°C ~ +85°C.
The chip inductors are wound around a ferrite core and are particularly suitable for cost-critical mass applications thanks to their surface-mounting capability. These material saving power inductors are ideal for applications such as storage chokes in DC/DC convertors as well as in the EMC sector.
DeMint (TPULF7032/7045) series conform to the RoHS directive and Lead-free. Custom parts are available on request.
DeMint will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information.
