In Part 2 of this series we indicated that a key element in a successful static control program was the identification of those items (components, assemblies and finished products) that are sensitive to ESD and the level of their sensitivity. Damage to an ESDS device by the ESD event is determined by the device''s ability to dissipate the energy of …

Learn more WhatsAppWhen the capacitor values are different, the smaller value capacitor will charge itself to a higher voltage than the larger value capacitor, and in our example above this was 6.9 and 3.1 volts respectively. Since Kirchhoff''s voltage law applies to this and every series ...
Learn more WhatsAppIf a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse …

Learn more WhatsAppApplying a voltage to such a capacitor with incorrect polarity causes a reversal of the electrochemical process used to create the capacitor''s dielectric layer. This process of electrochemically destroying the dielectric layer results in higher-than-specified leakage currents, which are exacerbated as the thinning dielectric layer begins to break …

Learn more WhatsApp4 · Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a …
Learn more WhatsAppAs the human body was originally the most common and damaging source of electrostatic discharge, the most common measurement of ESD sensitivity is by Human Body Model (HBM) electrostatic discharge. In this test a charged 100pF capacitor is discharged into the device via a 1500 W resistor.
Learn more WhatsAppEven when used within the capacitor''s maximum operating temperature, these capacitors may require a reduced voltage to maintain reliability. However, KEMET ceramic capacitors are designed and qualified to operate at full-rated temperature and voltage.

Learn more WhatsAppA simple technique to deal with ESD can be achieved by mounting multilayer ceramic capacitors (MLCC) at the PCB I/O connector pins that is the ESD entry point.EMC engineers recommend using 0603 MLCC''s placed at close proximity to each connector pin, mandating low-inductance mounting strategy associated with the PCB traces and vias.
Learn more WhatsAppThe ESD sensitivity of a device is usually specified in terms of the highest ESD test voltage that it passes and the lowest ESD test voltage that it fails per ESD model. Thus, ESD sensitivity is often expressed as a range of ESD voltage that a device can safely be subjected to for each of the ESD models.
