Inductor: Development of SMD Power Inductor VLM13580-D1/DR
( TDK -EPC Corporation)
Increased temperature characteristics and increased current rating compared to previous products of the company
TDK Corp. subsidiary -EPC TDK Corporation (President: Jianhong the vessel, hereinafter referred to as TDK-EPC) developed for the automotive engine electronic control unit (ECU) power supply circuit of a choke coil of the DC-DC converter with SMD The type of power inductor VLM13580-D1/DR will be mass-produced in October 2011.
This product has been designed to improve the temperature range of -40 ° C to +125 ° C in the past, taking into account the harsh operating environment of the vehicle, so that it can be used in a wider temperature range of -40 ° C to +150 ° C. At the same time, the ferrite core with low loss and improved DC overlap characteristics is further used to further improve the efficiency. In terms of rated current, our previous product VLM10555T-2R5M8R0-2H is 15A (Max), and the new product launched this time has a rated current of 20A (Max). There are 8 series of products for each inductance value (D1: 6 types, DR: 2 types).
main application
Choke coil for DC/DC converters such as automotive engine electronic control units
main feature
The maximum operating temperature is +25 °C higher than our original products, and can be used within the temperature range of +150 °C.
High current, low impedance
RoHS compliant to meet lead-free solder packaging requirements
Main characteristics

*IDC 1: The current value of the DC value in the DC overlap characteristic is 30% lower than the initial value (Typical value)
*IDC 2: Current value (Typical value) at 20 degC when the coil temperature rises by DC current
Coaxial Power D-Sub Solder Cup
Coaxial Power D-Sub Solder Cup Contacts with Mixed or Full Layout
Transmit Radio Frequency Signals
The Coaxial D-Sub have like the Power D-Subr replaced the two rows in a Standard Density connector with a coaxial contact that take up about the same size as the two rows of signal contacts. The Coaxial D-Sub is exactly the same size as the Standard Density connector but instead of example 9 positions of signal pins it has 2 power contacts , or instead of 37 positions of signals it has 8 coaxial contacts.
The Impedance for the coaxial contacts are 50Ω or 75Ω
The Coaxial D-Sub with Mixed Layout mixes both coaxial contacts and signal contacts in the same connector. For example the same size as a 15 position Standard Density D-Sub you can have what we call a 7W2, which means there is 7 contacts where 2 of them are coaxial contacts, which means there are 5 signal contacts, so 5 signals and 2 coaxial. See the Layout in the Tech Specs on the bottom, there are a lot of combinations of the Mixed Layout alternative.
Antenk's Coaxial D-Sub connectors are available in 5 standard shell sizes with 23 multiple contact arrangements. These reliable, robust combination d-sub connectors allow a combination of signal and coaxial contacts in cable mount, vertical board mount & right angle board mount termination type variations.
