High Frequency Isolation Transformer with 150°C Continuous Operation, Class H (180°C) Insulation, and 3000VAC Isolation for Oil Gas Downhole Equipment

High Temperature 150°C Class H High Frequency Isolation Transformer 200W

Purpose-built for extreme environment power conversion, this high frequency isolation transformer delivers reliable 200W operation at ambient temperatures up to 150°C. Using high-temperature polyimide-enameled copper wire, high-Curie ferrite cores, and specialized epoxy potting compounds rated for continuous thermal exposure, it is the transformer of choice for downhole oil and gas instrumentation, aerospace power systems, and deep geothermal monitoring equipment.

Key Features

• 150°C Continuous Operation: Validated through extended thermal cycling tests, maintaining full electrical performance at sustained 150°C ambient with minimal parameter drift.
• Class H (180°C) Insulation System: All insulating materials rated for 180°C hot-spot temperature per IEC 60085, providing a 30°C thermal margin at maximum rated ambient.
• High-Curie Core Materials: Specially selected ferrite grades with Curie temperatures above 230°C, ensuring stable magnetic properties across the full operating range without saturation risk.
• Ruggedized Construction: High-Tg epoxy potting provides mechanical reinforcement against vibration (tested to 30G per MIL-STD-202) and seals against moisture ingress.
• Enhanced Isolation: 3000VAC primary-secondary isolation barrier for safety-critical applications.

Applications

• Oil & Gas Downhole Tool Power Supplies (MWD/LWD)
• Geothermal Well Monitoring Electronics
• Aerospace Engine Control Power Modules
• High-Temperature Industrial Process Sensors
• Automotive Under-Hood DC-DC Converters
• Military/Avionics Power Conditioning

Reliability by Design

Each high-temperature transformer undergoes a rigorous qualification program including 1000-hour thermal aging at 150°C, thermal shock cycling (-40°C to +180°C, 100 cycles), and dielectric strength re-testing after environmental stress. Custom qualification protocols available for your specific end-application standards.
