Micrometals announces new additions to engineering kits in 200C Series materials -63 and -66. Kit-#63B and Kit-#66B offer a selection of larger toroids in four sizes from T130 to T250.

The -63 material mix is a 35 permeability material with excellent high-frequency characteristics which can be utilized to at least 10 megahertz. The -66 material mix is a 66 permeability material optimized for applications in the 100 kilohertz to 500 kilohertz range.

The 200C series of materials are designed for high-temperature applications, whether ambient or generated, and will not thermally age at temperatures up to 200 Celsius degrees. The cores are coated with a UL94V-0 rated material per Underwriter’s Laboratory file #E140098(S).

Each kit contains the following core sizes and quantities accompanied by the 200C Series catalog:

Each kit sells for $50 (US dollars). The precise ordering nomenclature is Kit-#63B for the selection in -63 material mix and Kit-#66B for the selection in -66 material mix. Please call today to get your design lab supplied with the latest in high-performance, high-temperature powder cores.

MICROMETALS INTRODUCES NEW 200°C-RATED, 85 PERMEABILITY LM085 MATERIAL GRADE (LM-zero-eight-five)

The LM085 grade of 200°C-rated materials is an 85 permeability material developed for high bias, low acoustic noise applications (low magnetostriction). LM085 exhibits excellent loss characteristics from 1 kilohertz to beyond 1 megahertz. LM085 demonstrates a limited rise of amplitude permeability as compared to our other higher-permeability materials, exhibiting 155% of its initial permeability at 2500 Gauss. This limited increase in permeability is applicable in the design of inductors exposed to widely varying AC flux, can tolerate limited inductance swing, and require a higher-permeability material.

For DC-biased applications, LM085 maintains 90% of its initial permeability at 14 Oersted. If considered for wideband applications, the permeability versus frequency characteristic varies by less than 10% from DC to 100 megahertz. Saturation flux density is beyond 14,000 Gauss. Temperature coefficient of permeability is -451 ppm/°C.

The LM085 material grade is immediately available in select toroidal sizes and can be sampled in specific shapes upon request. Please contact Micrometals, Inc., at (714) 970-9400 for more information or to arrange for samples to be sent for your evaluation. T94-LM085 core is currently priced at $0.376 each at 1000 pieces and lead time for production quantities is typically 8 weeks. Prices are subject to revision, please contact the Micrometals Sales Department for current pricing.
