TDKA series of automotive power is developed (TSE: 6762)CircuitFilm metal powerInductor. New TFM201210almainductanceThe mounting area of ​​the device is reduced by about 22% compared to TDK's traditional product TFM201610Alma (2.0 mm (long) x1.6 mm (width) x1.0 mm (height)) and will be mass production in August 2021.

In order to achieve electrification of various automotive control functions,Autopilot, Information communication, etc., recent installation requirements of ECU * have increased. Small inductors for power circuits help save installationSubstrateSpace,ADThe rapid advancement of AS performance also increases the number of components commonly used in the system architecture.

This series of inductors have a compact 2.0 mm (long) x1.25 mm (wide) size, the inductor core material also uses TDK unique metal magnetic materials. The thin film inductor supports the wide working temperature range from -55 ° C to + 150 ° C, reaching the highest level of industry ***. In addition, it also has anti-mechanical stress (such as the resin electrode structure)vibrationRobust characteristics of impact).

The TFM series includes a series of products with a range of rated voltages of 40 V, allowing direct and 12 V on the side of the automotive power circuit.BatteryConnection.

Glossary

• * ECU: Electronic Control Unit
• ** ADAS: Advanced Driving Assistant System

main application

• Automotive camera module
• V2X communication module

Main features and advantages

• Compact size 2.0 mm (long) X1.25 mm (width) X1.0 mm (high) helps save space
• Support the operating temperature range between -55 ° C ~ + 150 ° C (including self-heating)
• For the mechanical stress caused by the resin electrode structure and thermal shock, enhance robustness

Key data

* Isat *: Based on inductance changes (30% lower than the initial L value)Current

* ITEMP **: Current based on temperature rise (self-heating temperature rise 40 ° C)

* Rated current: The current value should be an ISAT maximum or ITEMP maximum, which is subject to the smaller.
