We introduced and developed MELF series cylindrical SMT resistors from 2000 under the requests of ENEL and some of our customers, there are several series of MELF resistors being widely adopted such as:
RJM series High precision MELF series are the right cross to Vishay’s MMA0204, MMB0207, SMM0204 , tolerance is up to ±0.05% and TCR is lower than ±5ppm/℃ ;
RGM series Ultra high working voltage MELF series was approved to be non inductance under working frequence 150MHz with resistance over 100M Ohm which is a great contribution to non-inductance components with ultra high resistance value! The maximum working voltage is up to 10,000V and the resistance value reaches 1G Ohm. RGM74S0411 series is exactly the same as our RG74 series which had been approved by TÜV RHEINLAND.;
RFM series non inductance MELF series has been approved with perfect non inductance performance over working frequency 17G Hz, much over the normal limit for non inductance resistors under 300M Hz.
