KEMET OHD5R-90B

OHD thermal protectors were developed to address thermal issues and meet safety standards, which have become increasingly important for electronic devices in recent years. Their unique patented design utilizes a magnet and a temperature-sensitive soft ferromagnetic material called Thermorite. As temperature rises, the magnetic flux density of this material decreases, transitioning to a paramagnetic material at the Curie temperature.

• High switching reliability
• Fast response speed
• Long service life
• Excellent environmental durability
• Compatible with signal levels from ultra-low (0.1 mW or lower) to high power (6 W)
• Extremely simple circuit design
• Compact, lightweight, and easy to operate
• Dustproof, explosion-proof, and corrosion-resistant
• Wide operating temperature range from +30℃ to +130℃ in 5℃ increments
• UL, CSA, and TÜV certified
• RoHS/REACH compliant
• Thermorite rapidly changes its magnetic properties at the Curie temperature with fast response time
• Thermorite Curie temperature is composition-based and does not change over time
• Thermorite exhibits stability against moisture and harmful gases
• Reed switches consist of a pair of Fe-Ni alloy reeds sealed in a glass tube filled with inert gas, switching via the magnetic field of a permanent magnet or electromagnetic coil
• Reeds magnetized by the magnetic field make contact and conduct; they separate and open when the magnetic field is removed
• Glass-sealed reeds ensure high environmental resistance and long service life
