API Delevan has introduced the HTPT66 series of high temperature power toroids. These toroids are intended for use in high operating temperature environments in switching power supplies, as output chokes, in EMI/RFI filtering, and DC/DC converters. They exhibit temperature stability, excellent saturation current characteristics, and are available in custom electrical contigurations. Standard inductances are 0.390µH to 100µH with current ratings as high as 18.3 Amperes direct current. The components operate within a temperture range of -55°C to +200°C, and available with either tin-lead or lead-free termination finish compliant with EU Directive 2002/95/EC and applicable amendments. Samples are available and production lead-time is stock to 4 weeks ARO.

API Delevan has introduced three new series of shielded surface mount power inductors: SP1812, SP1210 & SP1008. Recognizing the needs of design engineers, these power series are sized to industry standard packages for ease of circuit board layout. Inductance for series SP1008 range from 0.27µH to 100µH and max current ratings from 1.07A DC to 0.102A DC; series SP1210 range from 0.47µH to 390µH and max current ratings from 1.44A DC to 0.080A DC; series SP1812 range from 1.0µH to 390µH and max current ratings from 1.58A DC to 0.136A DC. All operate between 55°C and +125°C and are available with either traditional tin-lead or lead free, tin-silver-copper termination finishes.
