4 February 2014, Gowanda, NY (USA) – Gowanda Electronics achieved QPL status on four series: MLRF10M, MLRF15M, MLRF18M and MLRF17S.  These Gowanda series meet the military’s Qualified Product List (QPL) requirement for military spec MIL-PRF-15305. They also expand the company’s QPL-approved product line and demonstrate Gowanda’s ongoing commitment to the development and introduction of QPL products that address the needs of the military and aerospace markets.

These new wirewound, molded, thru-hole, RF inductors are designed for radio frequency applications in military, aerospace and defense communities. This includes use in communication, guidance and security applications, as well as in radar, test & evaluation and special mission applications.  The shielded MLRF17S series 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.  Technical parameters of all four series are outlined below.

MLRF10M is approved for MIL-PRF-15305 Military Part Numbers MS75083 (Phenolic core), MS75084 (Iron core), and MS75085 (Ferrite core). Performance includes: Inductance from 0.10 to 1000 µH; Q Min from 25 to 55; SRF MHz Min from 3.40 to 680; DCR Ohms Max from 0.08 to 72 and Current Rating DC mA from 28 to 1350. Operating temperature range is -55°C to +125°C for MS75083; -55°C to +105°C for MS75084 and MS75085.

MLRF15M is approved for MIL-PRF-15305 Military Part Numbers MS18130 (Phenolic core), MS14046 (Iron core), and MS90538 (Iron core). Performance includes: Inductance from 0.15 to 240 µH; Q Min from 33 to 75; SRF MHz Min from 5.9 to 525; DCR Ohms Max from 0.03 to 7.80 and Current Rating DC mA from 101 to 2450. Operating temperature range is -55°C to +125°C for MS18130; -55°C to +105°C for MS14046 and MS90538.

MLRF18M is approved for MIL-PRF-15305 Military Part Numbers MS75008 (Phenolic core) and MS75101 (Iron core). Performance includes: Inductance from 0.15 to 27 µH; Q Min from 30 to 65; SRF MHz Min from 22 to 510; DCR Ohms Max from 0.03 to 2.75 and Current Rating DC mA from 205 to 3000. Operating temperature range is -55°C to +125°C for MS75008; -55°C to +105°C for MS75101.

MLRF17S is approved for MIL-PRF-15305 Military Part Numbers MS75087 (Phenolic core/Iron shield), MS75088 (Iron core/Iron shield) and MS75089 (Ferrite core/Ferrite shield). Performance includes: Inductance from 0.10 to 1000 µH; Q Min from 40 to 60; SRF MHz Min from 3.8 to 250; DCR Ohms Max from 0.025 to 17.5 and Current Rating DC mA from 70 to 1790. Operating temperature range is -55°C to +105°C for the series.

6 May 2012, Gowanda, NY (USA) – Gowanda Electronics announces the introduction of the world’s smallest non-magnetic molded RF inductor series, SMG1812.  This new surface mount wirewound series will be featured at MD&M-East, a medical device industry conference and trade show being held June 18-20, 2013 at the Pennsylvania Convention Center in Philidelphia, PA. Visit Gowanda Electronics at booth #2836.

The dimensions of the new SMG1812 are 4.8  mm (length) x 3.4 mm (width) x 3.5 mm (height).  The overall size is more than 40% smaller than Gowanda’s SMG3013 series (the industry’s smallest non-magnetic molded RF inductor series until now).  Gowanda’s development of smaller inductor designs is in response to the ongoing market trend for smaller devices and therefore smaller components.

Inductors (in their role as filters) block certain frequencies that otherwise would compromise the performance of equipment or devices.  Gowanda’s SMG1812 was designed specifically for applications that are magnetically sensitive and therefore require non-magnetic components.  Relevant applications include test equipment & devices and medical diagnostic equipment – specifically imaging equipment such as MRI (magnetic resonance imaging) and particular types of X-ray equipment.

Technical specifications of the SMG1812 series include Inductance from 0.010 to 0.082 μH, Q min from 35 to 40, SRF Min from 750 to 1000 MHz, DCR Max from 0.1 to 0.25 Ohms, and Current Rating DC from 700 to 1230 mA.  A RoHS-compliant (“lead-free”) version is available and is denoted SMG1812LF.

It is anticipated that this new series from Gowanda will be used not only in the medical industry but also in a wide variety of market applications and industries where magnetic materials and magnetic characteristics must be avoided.  These other applications could include use in telecommunications, security systems, instrumentation, laboratory analysis equipment, aviation equipment, navigation equipment and electronic test equipment.

The new SMG1812 series expands Gowanda’s non-magnetic “MG” inductor product line.  Inductors manufactured using traditional methods can exhibit magnetic characteristics that are undesireable in certain applications.  Gowanda’s SMG1812 components (and the other series in the MG product line) are manufactured using a proprietary company-developed methodology that assures the inductors have non-magnetic characteristics.

Other members of Gowanda’s RF inductor “MG” product line include additional surface mount versions and through-hole leaded designs.  Technical specifications for those products include: Inductance options from 0.01 to 4.7 μH, DCR Max from 0.08 to 2.6 Ohms, and Current Ratings DC from 260 to 3835 mA. RoHS-compliant versions are also available.  Surface Mount Designs: SMG3013, SMG5025; Thru-Hole Designs: 10MG, 15MG.
