Miniature electronic components, surface mountable, are used in ever-increasing numbers in many areas of electronics.
Key requirements are for small dimensions, high temperature ratings and fast solderability. Norwe is a leading supplier of SMD-coilformers and components in high quality thermoplasts and with terminals to suit particular production requirements. Two examples are Norwe types EE (fm) SMD coilformer, and the SMD (fw) surface mount potting boxes.
The EE (fm) coilformers and SMD (fw) potting boxes are made in gfr-Polyphenylene Sulfide PPS (ryg), UL 94 V-0, temperature class N, +220°C and are suitable for reflow soldering. Special materials (eg, radiation cross-linking) and designs are available on request.
The coilformers have 'gull-wing' terminals. To prevent melt-out, these should ideally be mechanically-fixed when soldering on the wires.
The potting boxes are for surface mounting, as is common f.e. with filter chokes and ISDN transformers. The terminal type fw ensures a defined distance between potting box and PCB. The binding-on/soldering section of the terminal is accessible from the outside, the feet are easily positioned and electrical tests are possible.
Norwe also offers accessories that include pick and place caps, potting boxes and clips. SMD coilformers are only available with full sets of terminals. If required otherwise however, the company can be contacted for advice.
