Chip inductors for power and RF applications

14-02-2022 | Gowanda | Passives

Gowanda Electronics has introduced its first ceramic core chip inductor series for power applications – SMP0603. This new power series is perfect for test and measurement, industrial control and automotive sectors. These high-performance chip inductors can also be employed in RF applications in commercial, medical and defence markets.

The series was created to address the power electronics market demand for ceramic chip inductors with high current handling. An inductor with a high current rating is crucial for DC-DC converters and switching power supplies used in test and measurement equipment, industrial control equipment, and automotive applications including EVs and charging stations. This high-performance series is also ideal for RF environments, as well as communication, guidance, security, radar and test and measurement applications.

The performance range delivered by the 37 discrete parts within the series includes inductance from 1.8nH to 27nH, DCR Ohms from 0.01 to 0.04 and Current Rating mA DC from 1750 to 3400. All of its chip inductors, including this new series, fulfil a TML outgassing requirement of 1% maximum when tested in accordance with ASTM E595. Standard terminations are gold-plated nickel and RoHS-compliant.

The inductors are created with a flat top cover for pick and place assembly, and they are appropriate for reflow soldering. The operating temperature range for this power series is -40C to +125C.

Unlike other chip manufacturers, these chip inductors use co-fired terminations and fully encapsulated designs to satisfy the market demand for chemical resistance, vibration/shear resistance, electrical and mechanical integrity, durability during handling/processing and implantable device components (human body).

This product line expansion uses the company’s similarly sized ceramic chip RF inductor series, which has been optimised for higher current handling to make the new series ideal for power applications.
