Noise and Corrosion

Noise and Corrosion

R 1.9 NOISE R 1.9.1 Definition Noise manifests itself as a spontaneously fluctuating voltage whose instantaneous amplitude is randomly distributed. The instantaneous value is both unpredictable and of minor interest except in certain critical applications. Instead, one measures...

Pulse Load, Power and Voltage Derating

Pulse Load, Power and Voltage Derating

R1.7 PULSE LOADS In many applications the resistor will be subjected to pulse loads. We make distinctions between periodical/repetitive loads and pulse trains; on one hand, where the pulse is repeated at a certain frequency, and on the...

Resistivity, Thermal Resistance and Temperature Coefficient

Resistivity, Thermal Resistance and Temperature Coefficient

R1.1 RESISTIVITY (ρ) The resistivity, ρ, is a material constant. The higher the resistivity in the resistor material, the higher its resistance. The connection can be described as .............................. HereR = resistancel = conductor lengthA = conductor area....

Ripple Current and Power Load

Ripple Current and Power Load

C 1.5. Ripple Current and Power Load Capacitors are naturally limited by its capability to handle/dissipate ripple current and pulse energy load. The limitation may be significantly different by each capacitor technology but also within a specific product...
