    Mold Type Wirewound Resistors

    Thunder Precision Resistor Co., Ltd. has been making RXE series high precision wire wound resistors with both very low Ohm value and very high Ohm value as well as very low temperature coefficient.

    Thunder Precision Resistor Co., Ltd. can make wire wound resistance up to 38k with a small size 5W core.

    RXE series high precision wire wound resistors are of molding type with black encapsulation that is one kind of thermosetting plastics made by phenolic resin as adhesive with mineral filler and other additives. RXE series high precision wire wound resistors are highly isolated and could withstand over 1000V.

    The temperature of RXE series high precision wire wound resistors could be lower than ±10ppm/℃ and the tolerance could be high than ±0.05%.

    Thunder Precision Resistor Co., Ltd. makes RXE series high precision wire wound resistors to meet the requirements for current sensor and sample circuits in high precision instruments.
