0207 / 0309
Derating Curve
High voltage MELF metal film precision resistor, ready for the size of 0207/0309 , 1%, 100/200ppm. 1K~100Mohm. Max Overload upto 2500V. The MELF is cylindrical in shape and with metal electrode Leadless face resistor. Land pattern sizes are the same as SMD chip resistors. High quality of MELF resistors offer excellent electrical and Environmental Stability, exceptional stability demonstrated over life, biased humidity, and short time overload testing.
Features
- For SMD enabled structure.
- It is epoxy resin coating material.
- Lowest TCR control to 25ppm, normal type is 5% 200ppm, 1% 100ppm, 0.5% 50ppm.
- High voltage applications for power capacitor, motor start-up protection, car & motorcycle engine ignition, etc. other surge energy request able to design for engineer design request.
