Trimmer Capacitor Considerations in Practice

Posted by Rich Bestafka on Jun 3, 2020 7:45:00 AM

Trimmer capacitors are variable components used to calibrate RF circuits during manufacturing or servicing. These components allow for variable tuning--think oscillator frequency values or rise and fall times. Should values drift over the life of the device, trimmer capacitors can be recalibrated as needed. For sensitive applications like magnetic resonance imaging (MRI), these components help to optimize performance where any instability in time or temperature could impact the image output.

Medical Imaging Quality Starts by Selecting the Right Components

Posted by Peter Matthews on May 6, 2020 9:12:00 AM

Healthcare professionals and patients rely on magnetic resonance imaging (MRI) technology to examine soft tissues and organs in the body to detect a variety of issues, from degenerative diseases to tumors, in a non-invasive manner. To do this, the MRI machine uses a strong magnetic field and computer-generated radio waves to produce cross-sectional images. Thus, the quality of the MRI depends on the uniformity of the magnetic field – even the smallest trace of magnetism inside an MRI scanner can disrupt the field and degrade the quality of an MRI image.

Non-Magnetic Capacitors for Medical Imaging Applications

Posted by Peter Matthews on Sep 18, 2019 10:46:00 AM

Imaging systems account for a significant portion of the medical devices and electronics industry. There is an expanding range of imaging modalities, and one of the most common is magnetic resonance imaging (MRI). MRI equipment uses a strong magnetic field and computer-generated radio waves to create cross sectional images of the body; these images enable health care professionals to investigate and diagnose without the need for an invasive procedure.

Navigating Capacitor Screening Standards

Posted by Bob Nelson on Aug 14, 2019 9:25:00 AM

Compared to other applications, a medical implant is a rather benign environment for a capacitor; it’s temperature-controlled with a relatively low voltage. That being said, the success of a capacitor in a medical implant relies heavily on manufacturing components to avoid failures and the know-how to screen for any production discrepancies. As the reliability grade of a component progresses, more screening and testing is required to ensure that only the most robust parts make it to the finished product.

Capacitor Selection: Meeting the Demands of Medical Innovation

Posted by Peter Matthews on Apr 16, 2019 9:24:00 AM

As technology advances in the medical device space, electronics design is constantly adapting to meet industry needs. Since implantable medical devices must be embedded into the body, one of the main goals is to reduce physiological burden by minimizing the need for invasive surgeries. To achieve these goals, capacitors are just one of the many components that need to meet the demands of innovation, which today most commonly means the super-miniaturization of electronic circuits and advancements in capacitor materials and design.
