Benefit of Samwha Ferrite Cores

Power Materials for LDCs and OBCs

1. PL-13 : Moderate Flux Density and Core losses

PL-13 material has a moderate saturation magnetic flux density and low core losses over the entire temperature range, making it an excellent choice for any type of electric vehicle. This material shows the best efficiency at frequencies below 200kHz.

2. PL-15 : Higher Flux density and lowest core losses at 100 degree Celsius

High Flux Density of PL-15 helps to achieve high output while reducing the volume of the core. By slowing down saturation even at high currents, it reduces the heat generated by transformers and inductors, allowing for more reliable designs.

3. PL-17YH : Extremely Low Losses at wide temperature range

Our power material, PL-17YH shows a stable overall performance without sudden energy loss at room temperature as well as at high temperatures of 140 degrees or higher. This enables maximum efficiency in a wide temperature range required by eco-friendly vehicles.

Low Frequency (LF) Antenna

1. SM-23T : Stable permeability regardless of temperature change

SM-23 material maintains certain characteristics from extreme sub-zero temperatures to desert regions where the hot sun shines. Due to this high reliability, it is widely applied to LF antennas.

2. SM-43T : Higher permeability and insensitive to temperature changes

SM-43T with permeability of 4300 can be a good choice if you need higher permeability than SM-23T, which shows 2300 of permeability. SM-43T also has very little change in both low and high temperature range, so it is also a proper material to LF antennas.

High Curie Temperature Materials

1. SM-70T : Higher Curie temperature, more than 180 degree Celsius

Filters used in electric vehicles must maintain electromagnetic properties even at high temperatures. Since SM-70T does not lose its unique characteristics even at 180 degrees Celsius, designers can use it with confidence.

2. SM-85T : Higher permeability with high Curie temperature

The higher the permeability, the wider the range of applications for designers. In addition, materials with high permeability show high impedance characteristics. This SM-85T material also maintains its properties up to 180 degrees Celsius.

3. SM-100T : Higher Curie temperature with permeability of 10000

Generally, the higher the Curie temperature, the lower the permeability. However, our SM-100T is a material that can withstand temperatures up to 145 degrees Celsius, making it a great option for designers.
