The current part numbering system was introduced in 2004.
This is reference information for previous parts numbering system.
The terminals of aluminum electrolytic capacitors serve to draw out the electrodes.
The plating material for the terminals is tin (Sn) or tin-bismuth (Sn-Bi).
The time required for charging or discharging can be calculated by calculating the time constant. The time constant τ is expressed as τ = RC in an RC circuit.
Aluminum electrolytic capacitor specifications for temperature cycling are designed to be in compliance with JIS C5101-4.
SPICE model data is included as standard in LTspice. Please use in accordance with the procedures provided on this page.
When processing terminals for the purpose of mounting, make sure to fasten the lead line and make sure that no internal stress is imparted on capacitor.
We recommend using forming products for which terminal processing has already been conducted during the capacitor manufacturing process.
The rubber seal of radial lead-type aluminum electrolytic capacitors has concave and convex sections known as an air vent structure. During flow mounting, this structure helps prevent improper soldering due to thermal expansion of air existing between the rubber and substrate surface.
Aluminum electrolytic capacitors are components that are subject to wear. Product failure is judged based on service life , which is calculated using judgment criteria for electrical properties.
The measurement method and frequency of radial lead-type capacitors is standardized in accordance with JEITA RC-2003, and the value at a frequency of 40MHz is set as the ESL.
When measuring the ambient temperature of aluminum electrolytic capacitors, it is necessary to ascertain heat convection, heat radiation, heat conduction as accurately as possible.
Here, we introduce measurement methods using a dummy capacitor.
