Features and Applications
Small size SOT227, light weight, 600W high power resistor install on air-cooled heat sink or water-coolingis necessary.
New ceramics substrate shown highest heat conduction play small size high power resistor.
Completely resin filled structure provides high insulation voltage between heat-sink / resistor and partial
discharge performance, long-life stable operation.
2.5kV insulation voltage is standard and 4.0kV insulation is available in option.
Various 6 types of circuit configuration gives ease customer’s applications.
Very low series inductance and parallel capacitance make wide frequency range operation.
Applications include snubber resistors, filter resistors, bleeder resistor, current detect for automotive
electronics and many types of power electronics as UPS, power supply, professional audio.
