Introduction (TPUD4006/4008)
SMD unshielded wire-wound power inductors compact low profile to 0.8 mm. Token (TPUD) wire-wound inductor is designed for the smallest possible size and high performance with high energy storage and very low resistance. Those devices are ideal power inductors for notebook, DC-DC converter, digital camera and scanner, LCD Driver, and CD-Rom.
Utilize open Magnetic circuit construction and advance winding technology in manufacturing low profile (TPUD) series. The maximum height of TPUD4006/4008 is only 0.8/1.0 mm, TPUD4011/4013 1.2/1.45 mm, and TPUD5011/5013 1.2/1.5 mm.
The performance of the power components directly affects the overall efficiency of the supply in DC-DC converters and power supplies, so it is of vital importance. The TPUD5013 features low DC resistance, down to 0.081 ohm, and high rated current; up to 1.25 A is supported. Depending on version, the inductance values of these surface mount inductors range from 2.2 uH to 100 uH.
Token power unshielded inductors (TPUD) series conform to the RoHS directive and Lead-free. Custom parts are available for tighter tolerances on request. Application of specific designs also available including different inductance and frequency specifications adjusted to requirements. Please contact our sales for more information.
