SA Series Arrays

Surface Mount Filters

The SA Series of EMI filter arrays incorporate (4) three terminal chips in one compact footprint. These surface mount filter arrays are structured to minimize the residual inductance and ensure large insertion loss in the wide band.


  • Structure minimizes residual inductance with a high self resonant frequency, ensuring large insertion loss in a wide band
  • Common ground electrode built into the chip ensures complete grounding of all lines at the ground on both ends
  • Designed to control cross talk
  • Optimum constant can be selected from the capacity range of 22-22,000 pF to best suit the frequency
  • Solder plated nickel barrier terminations offer good solderability and resistance to soldering heat
  • Available lead free/RoHs compliant
  • Non-polar and surface mountable
  • Computer peripheral equipment
  • Telecommunications equipment
  • Power amplifiers
  • Power supplies
  • Temperature and motor controls

Storage Precautions

Deterioration of solderability can be caused by oxidization/ sulfurization due to the high temperature, high humidity or chlorine/sulfur gas. Parts should be used within 6 months if possible and stored below 40°C and below 70% RH in an atmosphere free of sulfur, chlorine or toxic gasses.

These EMI filters are made of ceramics. Please avoid dropping or other mechanical shock that could damage the parts.

The products kept in your storage for over 6 months should be used only after checking solderability.

Precautions for the safety use

The products are designed and manufactured for the use in ordinary electronic products. There is a possibility to cause performance deterioration or failure depends on the way of using. In case of the product breaking down in short mode, capacitor itself generate heat due to excessive current, and the circuit board may be damaged by a fire. Therefore, please talk to us in the case of these products are used in the applications/products which require high quality and reliability, where product defects or its misconduct might may directly or indirectly threaten human life or hurt human body, may damage properties etc., or may cause a social problem, please consult sales offices well in advance.
