Low Leakage Aluminum Electrolytic Capacitors- Wednesday, December 2, 2015

Low Leakage polarized electrolytic capacitors have been popular as a cost effective alternative to Tantalum capacitors.

With operating temperature ranges up to +125C in some versions they are versatile in design applications.

Low Leakage capacitors are often found in critical timing circuits where reliability is essential.

As an added benefit many Low Leakage Capacitors are also "Long Life" products with 2000 hrs at 85C at rated voltage a common attribute.

While Radial & Axial remain the most popular configurations we do stock & offer Low Leakage caps in Snap-in & Screw Terminals styles.

Some of the common Low Leakage series we get requests for include:

NICHICON TKB (axial) UKB, UKL(radial)
PANASONIC ECEAxxZxxx (radial)

We stock an extensive inventory of Low Leakage Capacitors.
Also, we have the ability to cross manufacturers (& supply tech data) for virtually any capacitor manufacturer.

Power Connectors / Cinch-Jones Plugs & Sockets - Monday, June 1, 2015

Power connectors are reliable with the ability to support high current and when  mating and unmating are required, all at an affordable price.  They are manufactured by Cinch. They were also made by Vernitron Beau who was acquired by Molex. 

  • Applications include:
  • Data Processing Controls
  • Medical Equipment
  • Industrial Controls
  • Communication Equipment.
  • Amusement and vending machines

These connectors are offered in two series 300 and 2400 with a variety of cable and panel mounting options.


  • 300 series:
      • Current rated at 10 amps                                                        
      • Voltage: 250VAC
      • Sizes 2 to 33 contacts
      • Polarized to prevent incorrect insertion
      • Used in light and medium applications
      • Beau equivalent series is 3300
      • Part # example:  Cinch P-308-CCT = Beau P-3308-CCT


  • 2400 Series:

KEMET Ceramic P/N Suffixes - Marking & Packaging - Wednesday, June 18, 2014

KEMET ceramic chips are available marked or unmarked (preferred) in several packaging styles. These ordering details are included as suffixes to the KEMET 14 digit part number, and will be used during the order entry process by KEMET sales personnel and distributors. (Notice that ordering a KEMET part number without a suffix will result in shipment of unmarked chips loose packed in a bag - so be sure to use a suffix if other packaging is needed.)

To speed up the ordering process, we use "shortcut" suffixes for the most common ordering modes. The most popular shortcut ordering suffix is "TU", which indicates unmarked chips, in labelled 7" tape & reel packaging. Alternatively, ordering suffix "TM" indicates marked chips, in labelled 7" reels. However, remember that marked chips are less likely to be in stock, and will have a cost premium associated with marking. Details on marking appear in our catalog, available on the website. Note that all 0402 chips and all Y5V chips are not available marked.

DESCRIPTION Unmarked Marking Required (Marking not available for any 0402 case size or commercial C0G and Y5V dielectric surface mount chip capacitors)

MKC/PS Capacitors- Thursday, May 8, 2014

MKC/PS Capacitors

Film capacitors are an important component in many of the circuits designed today. Engineers realize that the qualities and cost in using this style of capacitor are essential in producing the best product at the right price. However what happens when the material they would like to use has been discontinued by the manufacturer?  They can scramble around and try to find an alternative or they can contact Standard Radio. We have one of the industries largest selections of film capacitors in stock. Our product knowledge and tremendous inventory has made us a leader in supplying capacitors for over 60 years.

When they were still being made, polycarbonate and polystyrene capacitors were very popular in designs that needed stability and where a capacitor that was small in size was required. Both of these materials are no longer being made by the manufacturers and as a result capacitor manufacturers cannot make product using polycarbonate and polystyrene as the dielectric. Polypropylene and other materials have been offered as replacements but these are not exact replacements. Standard Radio has film capacitors in stock that use polycarbonate and polystyrene as the dielectric in brands such as ASC, Bishop Electronics Corp, CDE, Electronic Concepts, Electrocube, Philips, Sprague and many more of the industries preferred manufacturers.

Some of the qualities that are offered in a capacitor using polycarbonate and polystyrene as their dielectric are:

Excellent capacitance stability

Tight tolerances

High insulation resistance

Low dissipation 

Typical Applications:

Critical Timing Circuits           Feedback Circuits

Fixed Tuning Circuits             Power Supply Filtering

Gyro Circuits                          Integrating Circuits

Coupling & Decoupling          Pulse Forming Networks

Standard Radio has Polycarbonate and polystyrene capacitors in stock in DC voltages that range from 35VDC up to 630VDC. We have stock in both commercial grade and military grade polycarbonate capacitors. We have axial lead styles and radial leads styles both box type and molded in stock. We have included a suggested manufacturer cross reference list for these types of capacitors in an effort to help find alternates to these discontinued styles of capacitors.

Standard Radio has been a leader in supplying capacitors of every style for over 60 years. We offer our customers excellent customer service and provide them with product knowledge that is priceless. Contact us with any of your capacitor requirements and let us show why we are called the “King of Capacitors”.
