ZITN LHVR series High-Temperature Linear Power Supply Module is a dual-output precision voltage regulator circuit specifically designed for high-temperature and wide-temperature environments. It maintains stable output unaffected by input voltage fluctuations, load current variations, or ambient temperature changes. Without external filtering capacitors, its output noise remains below 1mV, and it operates reliably long-term at a case temperature of 275°C.

Dual-Output High-Temperature Linear Power Supply Module: MCM Process
The dual-output high-temperature linear power supply module adopts gold wire bonding (with fewer solder joints and low desorption risk), an integrated structure of skeleton and circuit (matched coefficient of thermal expansion to prevent warping and deformation), and sintered-sealed flexible connectors (to eliminate failure risks). It features advantages including high thermal conductivity (enabling rapid heat dissipation of power devices), hermetic packaging (resisting marine salt spray corrosion), modular assembly (shortening on-site operation and maintenance time), and high security (difficult to replicate and crack), making it suitable for meeting high-reliability requirements in extreme environments.
