- - Written by Amy Brown on August 06, 2020 The armed forces prevent most misfires through proper training and adequate maintenance. However, some missile systems fail to operate properly despite the efforts. ![AircraftMissiles](https://blog.spectrumcontrol.com/hs-fs/hubfs/AircraftMissiles.jpg?width=331&name=AircraftMissiles.jpg) There have been several missile misfire cases that have made the news. Take the misfiring incident that destroyed the German frigate, for example. The missile was propelled from the launcher but didn’t blast off. It burned out in the launcher, causing severe damage. Also, the Harpoon missile misfire incident was caused by a technical fault since it occurred without activating the launch key. In a case where bombers attack aircraft, fighter aircraft need these weapons to function correctly to be able to fight back. There should be no room for errors! What Causes Missiles to Misfire? Advanced ignition systems have only the mechanical and electronic components required to flag the detonator to launch the blast. However, Hazards of Electromagnetic Radiation to Ordnance (HERO) can impede the function of these detonators. One of the effects of HERO is that it causes missiles to disable prematurely or malfunction, hence the need for APITech’s EMI filters. **EMI Filters Help Prevent Misfires** EMI filtering is essential for all types of missile aircraft as it helps missiles to function correctly with no disturbance. The design of the EMI filter depends on some factors, including the type of aircraft, aircraft design, application type, and materials used. [APITech’s EMI filters](https://www.apitech.com/products/emi-filters-components-magnetics/discrete-coaxial-filters/), when incorporated into the ignition systems, will prevent these missiles from misfiring or malfunctioning. ![missile ignition systems](https://blog.spectrumcontrol.com/hs-fs/hubfs/missile%20ignition%20systems.png?width=300&name=missile%20ignition%20systems.png) Our EMI filter assembly types include: 1. **Hermetically Sealed EMI Filters -** This features a hermetic glass seal with a high EMI performance, filtering from 10 kHz to over 10 GHz. It is also reliable in harsh environmental conditions. 1. **Resin Sealed EMI Filters -** Feature a rugged case which makes them highly reliable even in the toughest environmental conditions. 2. **Discordial Ceramic Capacitors -** This is a great alternative to ceramic tube designs. They offer great versatility in meeting various capacitance, voltage, and dimensional requirements. EMI filters are used by the military to prevent misfiring, malfunction, and control electromagnetic interference in missiles. APITech of a large selection of high-quality EMI filter assemblies with full EMC compliance.
