Ceramic Capacitors

At the heart of any EMI Filter is a Ceramic Capacitor. Our extensive range includes Discoidal Feed-Through Caps, Tubes (F/T and Pi configurations), SMPS caps and Planar caps from leading manufacturer API Technologies. These filters are ideal for EMI/RFI suppression across a range of applications such as Military, Avionics, Industrial, and Medical.

Switch Mode Power Supply

High speed Switch Mode Power Supply (SMPS) Ceramic Capacitors have the following characteristics when compared to other capacitive elements:

  • Lower Equivalent Series Resistance (ESR)
  • Lower Equivalent Series Inductance (ESL)
  • Lower ripple voltage and less self heating

Planar Array Ceramic Capacitors

There is a wide range of Planar Array Ceramic Capacitors for EMI filtering. Built using over 25 years expertise in multi-layer ceramic capacitor manufacturing, planar capacitors offer many advantages over stand-alone chip, discoidal or tubular capacitors: low profile, compact, quick assembly time. Designs can incorporate multiple capacitance values, feed-thru holes and ground holes. With a combination of versatility and function, planar ceramic capacitors are quickly becoming the new standard in filtered connectors used in EMI suppression applications.

Features:

  • Unparalleled electrical performance & reliability
  • Fast prototyping & short product lead times
  • 100% electrical & dimensional testing of critical parameters
  • Custom packaging to suit end user needs

Discoidal Ceramic Capacitors

Discoidal feed-through ceramic capacitors are the building blocks of the EMI filter industry. Discoidal capacitors provide great versatility in meeting varied voltage, capacitance and dimensional requirements. Our non-polar, multi-layer capacitors are small, reliable and high in dielectric strength. Operational temperatures of –55°C to +125°C are achieved with no voltage de-rating.

Features:

  • Excellent high frequency performance
  • Low profile design
  • Rugged construction
  • Low impedance, many paths to ground
  • Low inductance, non-polar
  • AC applications up to 240V
  • DC applications up to 500V
  • -55°C to +125°C operation

Tubular Ceramic Capacitor

There is a wide variety of tubular ceramic capacitors, which are small in size, lightweight, non-polar and offer high dielectric strength. Operating temperatures of –55°C to +125°C are achieved with no voltage de-rating. All ceramic capacitors are fired to produce true monolithic structures, which are impervious to moisture and contamination.

Features:

  • Ideal for multi-pin connector applications
  • High ratio of capacitance to volume
  • Low inductance, non-polar
  • Impervious to moisture and contamination
  • -55°C to +125°C operation
