Surface Mount EMI Filter Array

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 wideband.

  • 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
  • An 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 another 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 safety use

The products are designed and manufactured for use in ordinary electronic products. There is a possibility to cause performance deterioration or failure depends on the way of using. In the case of the product breaking down in a short mode, the capacitor itself generates 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.

  • aerospace equipment
  • submarine equipment (submarine repeater, work equipment which used in the sea, etc.)
  • an atomic power control system
  • vehicle instrument including its accessories
  • fuel control equipment
  • other transportation equipment (vehicles, airplanes, trains, vessels, and traffic rights, etc.)
  • safety equipment
  • medical equipment (life-support equipment etc.)
  • power generation control equipment
  • disaster prevention and security equipment
  • for military and the Defense Agency applications
  • information processing equipment(communications infrastructure etc.)
  • other-equipment required the same quality and reliability as above equipment

In the case of circuit design using these products, the safety for end-users should be confirmed if the products have any problem. And the safety of products must be kept and the sufficient fail-safe design (secure the protection circuit) must be taken into consideration very well in order not to be unsafe as a system when the products are in defects by single trouble.
