Vista, Calif. In response to increased frequency demands, ACME Electronics Corp. has developed a new low core loss power material for high frequency electronics applications that provides excellent electrical stability over a wide temperature range for telecom and automotive applications, according to the company.
This soft ferrite material, designated P46, exhibits similar saturation flux density and inductance to ACME's popular P4 material. This will enable an increase in power efficiency without requiring changes to the circuit design and PC-board layout or adding cost to existing circuit and board designs. Applications for the new P46 low core loss material include switch mode power supplies, dc/dc converters, power inductors and power chokes.
The P46 ferrite material exhibits an initial permeability of 3300 ±25% at 10 kHz, 0.1 mT (25°C). Saturation flux density is 200 mT at 25°C to 50 mT at 100°C. Core loss characteristics are 400 kW/m3 at 200 mT, 100 kH (from 25°C to 100°C). Operating frequency is 25 kHz to 500 kHz with a working temperature range of -20°C to 100°C. The P46 material is offered in a range of standard and custom shapes including popular low-profile geometries such as ER, ERI, PEI, PEE, and low-profile RM and POT/CUT cores.
Typical pricing is less than $0.110/set for the P46ER9.5/5 material and less than $0.175/set for P46ER13.
