Nichicon New Pencil Shaped Aluminum Capacitors

Monday, July 11th, 2011

Nichicon’s new pencil shaped aluminum capacitors are available in two series:
CS and PZ. They are designed to provide large capacitance, voltage and ripple current for low profile applications where traditional sized capacitors would be too big. A lower height is achieved by laying the capacitor on its side for mounting. Normally a power supply needs a capacitor with high voltage, capacitance and ripple current on the input side. In the case of a large power supply, usually a bulky can type capacitor is used. In the case of a small power supply, typically a radial type is used by mounting it vertically or horizontally. In recent years, the flat screen market has exploded and makers have requested a lower height capacitor to achieve a slimmer product. The usual response has been to make a bigger diameter and lower height part.

However, there was a tradeoff with voltage, capacitance and ripple current so this was not an optimum solution until the pencil capacitor was designed. With the smaller diameter, longer length and laying horizontal on the circuit board, this provided what the designers were demanding.

Key advantages to the pencil shaped capacitors:

Advantage #1: Lower Height Product
By laying the capacitor on its side, a lower height is achieved making it
attractive for low profile applications. Diameters range from 9 to 12.5mm.

Advantage #2: Larger Capacitance by Going Parallel
Multiple capacitors can be put in parallel to achieve much higher capacitances
and ripple currents but without increasing in height.

Advantage #3:  High Capacitance in Small Size
With a low height dimension, large capacitance is available up to 270
microfarads.

Advantage #4: Low Cost per Capacitance
When compared to other capacitors like ceramic, film and tantalum,
aluminum is the lowest cost per microfarad.

Advantage # 5: High Voltage
The pencil caps are available in voltages from 200 thru 450 Volt.

Carling: PC-Series Ground Fault Circuit Protection

Monday, July 11th, 2011

Carling Technologies Inc is pleased to announce the addition of the 1-50 Amp PC-Series circuit breaker to its ground fault circuit breaker product portfolio.
The PC-Series is suitable for:

  • AC branch ground fault protection – a single circuit solution
  • AC main ground fault protection for a boat’s entire AC electrical system
  • Portable generator ground fault protection

Key Benefits of the PC-Series:

  • Increases safety around boats and marinas
  • Protects against electrical shock hazards in areas near water
  • Protects against defects in the wires & conductors
  • Reduces fire and shock hazards from defects in permanently installed appliances such as water heaters, battery chargers, lighting fixtures, etc.
  • Detects lower level ground faults which do not trip ordinary circuit breakers, but can lead to fires, and shock hazards for boating occupants

Innovative Features:

These precision mechanisms are temperature stable and are not adversely affected by temperature changes in their operating environment. As such, derating considerations due to temperature variations are not normally required, and heat-induced nuisance tripping is avoided.

  • Overload, short circuit and ground fault protection in a single package
  • Handle style actuators and rocker style “acuguard”
  • Wiping Contacts – Mechanical linkage with two-step actuation – cleans contacts, provides high, positive contact pressure & longer contact life
  • A trip-free mechanism, a safety feature, makes it impossible to manually hold the contacts closed during overload or fault conditions.
  • A common trip linkage between all poles, another safety feature, ensures that an overload in one pole will trip all adjacent poles.
  • Front panel mounting
  • Integral push-to-test button
  • Two integrated LED indicators distinguish if a breaker is closed with Line Voltage present, or has opened due to leakage current, or has opened due to over current, or is closed with no Line Voltage present.
