New surface-mount inductors target power applications

16-03-2015 | Gowanda | Passives

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.
