Subminiature Coaxial Switch 1.6 mm High, DC to 6 GHz
MS-156 Series sOverview
Developed for inspection of high frequency circuits used in portable terminals.Verification of the circuit performance is accomplished by simply inserting the external plug in the board mounted receptacle.This action re-directs the circuit from normal condition to the plug side. Removing the plug restores circuit to its normal condition.
Space-saving design Low profile -1.6 mm protrusion above the board. Lightweight -0.025 g. total weight.
sFeatures
1. Low insertion loss
0.1 dB typical at 6 GHz (not mated with the plug).
2. Space-saving design
2.7 mm x 2.7 mm occupied board space.

BPrecautions
1. Care should be taken to avoid accumulation of moisture inside the mounted receptacle after the washing process. 2. This product is intended to be used for circuit inspection only. Consult factory if any other application is considered. 3. The corresponding plug should be inserted in direction perpendicular to the switch mounting surface, within an angle of 2. The push-in force should be kept within 6-10 N. 4. Do not use hand soldering for mounting on the board. Doing so could result in solder and flux wicking to the contact portion. 5. When using a heat gun, hotplate, or similar methods, limit the temperature to 260c applied for 10 seconds max. 6. Consult Hirose if your application, installation methods or end-user environment are different than the recommended.
