precision Melf Resistors With High Stability

Thunder Precision Resistor Co., Ltd. designed and have been producing cylindrical surface mounted MELF resistors RJM73E0204 series mold type with high stability and reliability to match the performance of UXA0204 resistors made by Vishay.  

Melf resistors are so called as cylindrical SMT resistors and non-leaded SMT resistors. RJM73E0204 is one of the small sizes melf resistors that is the same size as 1206 type chip resistors.

RJM73E0204 series MELF resistors are the right crosses to Vishay's MELF resistors UXA0204.

Production in Thunder Precision Resistor Co., Ltd is strictly controlled and  follows and extensive set of instructions established in production procedure for reproducibility. A homogeneous film of metal alloy is deposited on a high grade ceramic rods  (93%~96% AL₂O₃) made by Ceramtec Germany and conditioned to achieve the desired temperature coefficient. Nickel plated steel termination caps are firmly pressed on the metalized rods while the rods are aluminum terminated for eliminate voltage noise and current noise.

A professional laser is pressed on the metalized rods to not only achieve the target value but also prefect electronics performance by smoothly cutting a helical groove in the resistance layer on the ceramic rods without damaging the ceramics. The resistance layers are covered by a protective coating and hard bakelite designed for electrical, mechanical and climatic protection.
