These series deliver nearly 2X or more improvement in SRF and Current Rating compared to traditional designs.

Gowanda, NY (USA) – Gowanda Electronics, a designer and manufacturer of precision electronic components for broadband radio frequency and power applications, announces the introduction of several High Performance RF Surface Mount Inductor Series. Recent advancements in the company’s design technology and manufacturing capability deliver significant improvement – nearly 2x or more – in SRF and Current Ratings for these new inductors as compared to traditional molded designs with equivalent inductance. The first six series – CC4H1008, CF4H1008, CC4H1210, CF4H1210, CC4H1812 and CF4H1812 – will be featured at the 2018 International Microwave Symposium (IMS2018) being held in Philadelphia, Pennsylvania from June 12 to 14. Visit Gowanda’s booth #1735 for more information.

These series were developed to address market needs and industry trends calling for ever-increasing performance from RF SMT inductor components. These CC4H (ceramic core) and CF4H (ferrite core) series were designed for use in radio frequency applications in commercial, medical and military markets. That includes use in communication, guidance, security, radar, and test & measurement applications.

The performance ranges provided by these six new wirewound series include inductance from 0.0082 µH to 1000 µH, Q min from 30 to 75, SRF MHz min from 2 to 4000, DCR ohms max from 0.060 to 30 and current rating mA DC from 96 to 2430. Series-specific data ranges are provided in the table below. Operating temperature range is -55°C to +125°C for all series. More technical information is available on each series at the company’s website.

Shielded Surface Mount RF Inductors with Higher Inductance

Gowanda expanded its SML32S “1210” Shielded Series, increasing the number of parts by 20% and raising the upper level of inductance to 470 uH.

Gowanda, NY (USA) – Gowanda Electronics, a designer and manufacturer of precision electronic components for radio frequency and power applications, announces the expansion of its SML32S series of wirewound, shielded, molded RF surface mount inductors in the “1210” style. This expansion increases the number of individual parts in the series by more than 20% and broadens the inductance range by adding values from 120 to 470 uH.

The expansion was done in order to address the market need for higher inductance shielded inductors in RF applications. Shielded inductors are used specifically in applications where the close proximity of circuit board components requires the inductor to be shielded to minimize interactions and ensure performance of the overall system. Such inductors are used for radio frequency applications in commercial, medical and military communities. That includes use in communication, guidance, security, radar, and test & evaluation applications.

The performance range provided by the expanded SML32S series includes inductance from 0.1 uH to 470 uH, DCR ohms max from 0.15 to 25 and current rating mA DC from 91 to 1175. There are two core types in the series (powdered iron or ferrite). The series operating temperature range is -55°C to +125°C. See table. Links to series information, series datasheet and other helpful information are provided below.

First in Industry – RF Surface Mount Inductors with Established Reliability

admin — Tue, 23 Jan 2018 18:34:19 +0000

Gowanda, NY (USA) – Gowanda Electronics, a designer and manufacturer of precision electronic components for radio frequency and power applications, announces the introduction of the industry’s first off-the-shelf Shielded RF Surface Mount (SMT) Inductors with Established Reliability (ER) rating. The first-ever shielded ER SMT series – Gowanda ER5025S – complements MIL-PRF-39010 Qualified Product List (QPL) axial-leaded (thru-hole) products and enables their conversion to SMT circuitry via this new MIL-PRF-39010 qualified SMT series. This series was developed by the company in response to a market need for shielded surface mount options to the traditional thru-hole designs. SMT components enable the use of more efficient assembly methods when compared to thru-hole methods. Gowanda was the first in the industry to offer an ER series in a surface mount configuration last year, Gowanda ER3013.

“This introduction of a shielded ER surface mount series is a result of Gowanda’s commitment to develop inductor designs that address the evolving needs of the design engineering community,” said Don McElheny, CEO of Gowanda Components Group. “We will continue to introduce more ER SMT series in the future”, he added.

The ER5025S series meets the military’s QPL requirements for Established Reliability to failure rate level M and addresses two MIL-PRF-39010 slash numbers (/17 and /18). This qualification required extensive testing for electrical, environmental, mechanical and thermal performance. Level M represents the first level of failure rating for off-the-shelf inductors for high-reliability applications. In its ongoing commitment to the military market, Gowanda intends to achieve higher level failure ratings (Level P, then Level R) as ongoing testing continues to accumulate the hours necessary to attain those ratings on this shielded ER SMT series.

Gowanda’s wirewound, molded, shielded ER5025S series is designed for RF applications in military, aerospace and space – including defense and NASA communities – for use in communication, guidance, security, radar, test & evaluation and special mission applications. This shielded series – with 3% max coupling – is used specifically in applications where the close proximity of circuit board components requires the inductor to be shielded to minimize interactions and ensure performance of the overall system.

The performance range provided by the ER5025S series includes inductance from 0.10 to 10,000 µH, Q min from 40 to 60, SRF MHz min from 1.0 to 450, DCR Ohms max from 0.025 to 139, and current rating mA DC from 30 to 2245. The MIL-PRF-39010 slash number determines specific performance, core type (phenolic, powdered iron or ferrite) and shielding type (iron sleeve or ferrite sleeve). Operating temperature range is -55°C to +105°C. See the performance data table and ER5025S datasheet link below for additional information.

Gowanda has been designing and manufacturing RF and power inductors – both thru-hole and SMT – for the military’s Qualified Products List for many years. That experience combined with several successful ER thru-hole qualifications set the stage for the development of the industry’s first ER SMT inductors last year, and now the industry’s first shielded ER SMT inductors. Gowanda’s new Hi-Rel QPL Brochure provides a helpful overview.
