DMTL Increases Focus On Passive Components For High-Rel Military Applications
Leading passive components distributor DMTL is increasing its focus on components for military and aerospace applications and is working alongside a number of manufacturers currently building products for high reliability applications.
DMTL has been around for almost 25 years working alongside a number of industry leading component manufacturers helping customers to integrate the latest passive components into their designs. Today, these suppliers include AVX, Kyocera, Holystone, Viking Tech, Thinking Electronics and Coilmaster.

As a result, DMTL is now recognised by many as a leading supplier of circuit protection devices, frequency control components, resistors, capacitors and specialist connectors as well as a variety of ceramic devices and sensors and is able to supply a wide variety of components approved to relevant military standards.

“Designers of electronics-based systems for high reliability applications never compromise on their choice of components.” Says Pete Jones, DMTL’s Commercial Director. “As a result, component manufacturers and suppliers must meet an array of quality, reliability and performance standards which ensure that each and every part will function correctly in the harsh electrical and mechanical environments often encountered in military and aerospace applications.” Pete Jones adds. “Vibration, extremes of temperature and electromagnetic compatibility are just some of the conditions that must be overcome if a critical system is to perform.” He adds.

With a huge choice of electrical specification, format and size from which to choose, matching the passive component to an application is no easy task and it is a specialist distributor’s design and component integration expertise that customers look for. DMTL works with its customers from initial project concept to final production helping designers with their component selection and their purchasing teams with inventory management.

One of the manufacturers that DMTL turns to for MIL-spec product is the leading passive components manufacturer AVX which produces a wide variety of High-Rel ceramic and tantalum capacitors and is recognised by many in the industry as a driving force in high performance passive component development.

AVX has several purpose-built facilities that only manufactures passive devices for military and aerospace applications and has been responsible for many recent advances in capacitor performance and size reduction.

DMTL has worked alongside AVX for many years not only helping customers to design-in existing AVX products, but also assisting in the development of new components specifically for DMTL customers and their applications. AVX passive components can be found in many military applications including communications systems, fighter aircraft, UAVs and weapons.

Here are just two examples of how AVX is pushing the barriers in chip capacitor technology.

With the trend very much towards reducing size while maintaining or improving performance, AVX recently announced the world’s smallest military approved tantalum chip capacitors in capacitance/voltage combinations previously only available in much larger packages. Based on the revolutionary AVX TACmicrochip technology, these offer designers a significant opportunity to downsize circuits for military and aerospace applications.

As well as producing the smallest device, another recently introduced and military approved AVX product range offers the most flexible of surface mount form factors, offering nine case sizes. The molded construction is compatible with a wide range of surface mount assembly processes including wave or reflow solder, conductive epoxy or compression bonding techniques.

DMTL is currently helping a number of manufacturers of military and aerospace products with all manner of design initiatives. Many of these manufacturers are market leaders in a variety of sectors including communications and control systems, power supplies and medical systems where the same high performance and reliability issues are key.
