Introduction

DC Blocks are often used in CATV or Satellite reception systems to block DC current and protect downstream equipment.

Important criteria to judge the quality of a DC Block are insertion loss, return loss and voltage withstanding.

A low insertion loss is important to ensure minimum attenuation of the signal caused by inserting the DC Block.  A high return loss ensures a good impedance match and keeps the signal free of unwanted reflection interference.  A high voltage withstanding is necessary to guarantee a better protection of the downstream equipment.

Soontai's newly developed DC Block embodies excellent performance in all three above mentioned criteria.  At the same time it is mini-size with dimensions of only 12.5 x 30 mm. The housing incorporates a hexagon-nut shape for easy installation with a spanner.

Our DC Block is also suitable for other electronic and testing equipment.
