New surface-mount inductors target power applications

Gowanda Electronics has introduced the SMP2512 Series of surface-mount wirewound ferrite-core, moulded power inductors. The new series addresses a market need for a specific combination of size and performance in the power electronics industry, says the company. The SMP2512 Series is designed for use in power applications requiring a specific surface mount size - nominally 0.25 inch L x 0.10 inch W, and current rating performance 0.26 to 1.64A DC for an inductance range of 1 to 100uH. The power inductors are epoxy-encapsulated for environmental protection and superior strength to withstand all types of reflow soldering. The SMP2512 Series is aimed at DC-DC converters and switching regulated power supplies. Rugged construction enables the SMP2512 inductors to be used in these applications as well as in many other power supply applications where current handling capability and durability are important. Specific applications include microprocessor and distributed power applications - including power supplies, power regulators and DC to DC converters - especially in automotive electronics, industrial process control equipment, medical diagnostic equipment and test and measurement equipment. Other applications include use in bar code, instrumentation, laboratory analysis equipment and security systems. Technical specifications for products in Gowanda's SMP2512 inductor series include: Inductance from 1 to 100uH with 5%, 10% or 20% tolerance, DCR max from 0.15ohm to 6ohm, current ratings from 0.26 to 1.64A DC and saturation current from 0.195 to 1.23A DC. Operating temperature range is -55C to +125C. Both Pb and RoHS (lead-free) versions are available. Inductors are provided via tape and reel packaging for ease of use in surface-mount assembly operations, says the company.
