The 10WS Thermal Fuse Cement Resistor combines resistance and thermal fuse protection in a single cement resistor structure. It is designed for circuit board protection and electronic circuits where both resistance control and thermal protection are required.
For B2B applications in Japan and Korea, the product can be positioned as a thermal fuse resistor, fusible cement resistor, and circuit protection resistor. Its flameproof ceramic case provides the basic construction for applications requiring insulation and resistance to humidity, while the product specifications include testing for short-time overload, dielectric withstand voltage, load life, and moisture-proof load life.
The product documentation references IEC 60115-1 and JIS C 5201-1, making JIS C 5201-1 a relevant technical reference for Japanese-market product positioning.

The product is tested at AC 1000V for 1 minute under the dielectric withstand test, providing a specific reference for insulation performance.
The moisture-proof load life test is conducted at 40°C and 95% relative humidity for 500 hours. This provides a measurable environmental test condition for applications exposed to humidity.
The load life test uses rated power loading with 90 minutes ON and 30 minutes OFF at 70°C for 1000 hours, with the specified resistance change at R/R≤5%.
The short-time overload test is conducted at 10 times the rated wattage for 5 seconds. For the power film construction, the specified test condition is 5 times the rated wattage. This provides a measurable reference for short-duration overload capability.
The resistor can be used in circuit board protection positions where resistance and thermal fuse functions need to be combined. Its thermal fuse structure provides an additional protection function within the resistor component.
The product can be applied to protection sections of power-related circuits. Its documented anti-surge characteristics and short-time overload testing make it relevant to resistor applications where transient electrical conditions need to be considered.
The resistor can be used in protection sections of electronic control boards, particularly where a flameproof cement resistor construction and insulation characteristics are required.
