Terminology and General Information - DISC CAPACITORS Due to ageing it is necessary to quote an age for reference measuerements which can be related to the capacitance with the fixed tolerance. As defined in CECC 30700 this age is 1000 h. If the age of the capacitor is known, the capacitance for t = 1000 h can be calculated using known ageing constant : k = 100 (C1- C2)/[C1* log t1/t2] => C2 = C1* [ 1- k/(100*log(t1/t2))], where k is ageing constant in %, t1, t2 are measurement time points and C1, C2 capacitance values at time t1 and t2 respectively. It is important to de-age the capacitors...

Safety ceramic disc KZ capacitors are intended for galvanic separation of mains and conductive parts that might be touched, i.e. antenna inputs in radio and TV sets. They are ideal for line by-pass, antenna coupling and across-theline applications, especially for the circuits exposed to danger of electric shock. These capacitors meet safety rules applicable to electronic apparatus and associated fittings for domestic or similar general use, connected to mains according to EN 132 400. KZ capacitors offered by KEKO VARICON cover capacitance range from 330 pF to 4700 pF, operating at AC rated...

HIGH VOLTAGE CERAMIC DISC CAPACITORS High voltage ceramic Type 2 disc capacitors cover cpacitance range from 330 pF to 10 nF operating at voltages from 1 to 6 These capacitors utilize high dielectric constant (K> 8000) ferroelectric formulations based on barium titanate. They exhibit markedly nonlinear temperature characteristics, significant dependence on voltage and frequency and predictable decay of capacitance with time. Such capacitors are suited for by-pass, coupling and filtering applications, where Q, high insulation resistance and stability of capacitance characteristics are not of...

VARICON Assembly Recommendations for TH Components Very often before soldering of through-hole component its leads are being bent. It is important not to damage the component during lead bending. Typical damage produced during bending are cracks in epoxy pants, which can lead to increased humidity sensitivity of component and consequentially to its shorter life time. In order to avoid epoxy pants damage it is necessary to : -fix the most sensitive point (epoxy pants) of component body -bend wire at least 2 mm below the end of epoxy pants Another potential damage of the component which can...
