Bourns launches transformative EdgMOV varistor family to provide space-saving surge protection solution

Posted Date: 2024-01-20

Bourns® EdgMOV Varistors are available in a single form factor and multiple model options, allowing designers to reduce the size or increase the effectiveness of their surge protection solutions

2024Year1moon18day - Bourns, a leading global manufacturer of electronic components for power, protection and sensing solutions, introduces its advanced, space-saving EdgMOV varistor series, which delivers breakthrough surge performance in a space-saving design Protection performance. This revolutionary design allows designers to determine the size and level of surge protection in a given application.
The Bourns® EdgMOV Varistor Series offers multiple model options, allowing the choice of a higher surge rating but lower clamping voltage, or a protection solution with the same surge rating but a smaller diameter. EdgMOV varistors also provide additional flexibility, allowing designers to select higher MOV voltages while maintaining the same clamping voltage, helping to reduce the risk of failure due to MOV leakage current.

The EdgMOV varistor family is available in four model series sizes: 7 mm, 10 mm, 14 mm and 20 mm with current ratings of 1.5 kA, 3 kA, 5 kA and 8 kA respectively. EdgMOV chip varistors are designed to match common MOV packages and can be directly replaced without any PCB redesign. Bourns® EdgMOV varistors provide surge ratings comparable to the newer generations of larger conventional MOV components, e.g. the 10 mm Bourns® EdgMOV surge protector is rated for 3 kA nominal current (15 times operation), which is comparable to today's typical 14 mm standard MOVs (which are also typically rated at 3 kA). Conversely, if designers wish to improve the performance of the main protector without increasing size, they can select a similarly sized EdgMOV protector to replace the existing MOV, providing enhanced performance in the same package size. Another advantage is that the coating material used is rated for service temperatures up to 105°C, higher than the standard 85°C. UL requires components rated above 85 °C to undergo a 1,000-hour burn-in test to help extend the maximum equipment life for the end user.

The Bourns® EdgMOV chip varistor series is now available, and the entire series is RoHS* compliant and halogen-free**. For more detailed product information, please see:

*RoHS Directive 2015/863 of March 31, 2015 and its annexes.

**Bourns products qualify as "halogen-free" if (a) the bromine content is less than or equal to 900 ppm (b) the chlorine content is less than or equal to 900 ppm, and (c) the sum of bromine and chlorine content is less than or equal to 1500 ppm.
