Anti-Surge Leadless 0204 0207 0309 SMD Fusible Wire Wound MELF Carbon Metal Film Resistors 0.125W 0.25W 0.5W 1W 2W

Anti-Surge Leadless 0204 0207 0309 SMD Fusible Wire Wound MELF Carbon Metal Film Resistors 0.125W 0.25W 0.5W 1W 2W

Metal Electrode Leadless Face (MELF) Resistors are round or cylindrical in shape. They are available in embossed plastic tape on 7" reels. The terminals on MELF resistors are force-fitted steel caps with Sn plated termination. Parts are also available in Zero-Ohm value. Land pattern sizes for MELF resistors are the same as SMD chip resistor.

Notes

* MELF is the acronym for Metal Electrode Leadless Face.
* 90/10 solder plated end caps.
* Suitable for reflow and wave soldering.
* Meets or exceeds EIAJ 8009, EIA PDP 100.
* Force fitted steel caps are tin plated. SnPb is available upon request based on availability.
* Tape type is plastic.
