Gowanda Electronics has introduced the world's smallest non-magnetic molded RF inductor series, SMG1812. This new surface mount wirewound series will be featured at a medical device industry conference and trade show.
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.
