RX24-oxidized gold aluminum shell
 
I. Features
Good heat dissipation, suitable for heat sink installation
High insulation
Fully welded structure
Install on the substrate to apply heat absorption effect
Molded structure with environmental protection
There is no inductive winding to the lowest reactance component
Good reliability in operation
Comply with MIL-PRF-18546 application specification
III. Material description
Resistance wire: copper-nickel alloy or nickel-chromium alloy, depending on the resistance value
Core material: ceramic or steatite porcelain depends on the physical size
Sealing material: silicone molded plastic (silicone plastic additives are mainly composed of ultra-high molecular weight polysiloxane. Mainly used as a thermoplastic processing aid,
It overcomes the processing troubles and performance deficiencies of traditional silicone additives, and is safe to use, easy to mix, stable in performance, and easy to disperse in the resin.
● It can significantly improve the processing properties of injection molded products such as mold filling, internal lubricity and mold release;
● Reduce the torque of the screw, reduce energy consumption, improve production efficiency, reduce the scrap rate, and extend the service life of the equipment;
● Improve the scratch resistance of the product, reduce the friction coefficient of the product, and reduce the amount of wear;
● Improve flame retardancy, reduce smoke density, improve surface gloss (glass fiber reinforced plastic), and improve the mechanical properties of products (highly filled plastic);
● Has good stability and non-migration).
Housing: Anodized aluminum housing
Cap: stainless steel
Leading terminal: tinned copper or stainless steel rod with thread
IV. Special changes
The aluminum housing resistance can be changed as follows according to customer requirements:
Terminal shape and material
Resistance tolerance
Low TCR
Shell shape
Mounting hole thread
Preprocessing and other additional experiments
V. MIL specification application
Structural features: It is a combination of spring alloy resistors and rows of aluminum shells, after high-temperature anode treatment, and then filled with special non-combustible heat-resistant cement,
After being dried in the shade, it is made of fixed insulation by high temperature treatment. High heat dissipation aluminum alloy shell package; tight, firm and fully sealed filling material
Easy to dissipate heat; has strong weather resistance and vibration resistance; small size, high power, strong overload capacity; convenient and stable installation, beautiful appearance.
Application: Suitable for industrial machinery, load testing, power distribution, instrument equipment, automatic control devices... etc. (such as elevators, cranes,
Braking equipment such as port machinery, rolling mill, hoist, generator, frequency converter, etc.)
Operating environment: rated power temperature (+70℃); operating temperature range (-55℃～+375℃), suitable for use in high requirements and harsh environments.
Structural form: fixed housing installation, high temperature resistant wire leads
