Description
Technical field
The present invention relates to a kind of electronic devices and components, particularly relate to a kind of super capacitance/voltage-resistor resistor, belong to piezoresistor manufacturing technology field.
Background technology
Varistor, owing to having nonlinear characteristic and the energy absorption capability of excellence, is therefore applied on electric power, electronic circuit widely.Along with high and new technology development, equipment is short, little, light, thin, functionalization, digitized, intellectuality, low consumed development trend, and the antistatic of equipment, anti-interference protection will seem more and more important.Ultralow pressure varistor, as ultralow pressure Anti-surging power protection device, is widely used in the fields such as mobile phone, USB interface, computer, LCD, automotive electronics, IC chip.The SMD varistor of ultralow pressure relies on Japan, Germany, Korea S's import substantially at present, and owing to its internal structure is mainly thick film lamination, volume is little, but this device the most generally exists a defect, i.e. through-current capacity is little.When circuit running into big electric current and passing through, it is susceptible to punch-through.Therefore, in direct current ultralow pressure circuit, it is also possible to its security performance is improved.
Summary of the invention
It is an object of the invention to for ultralow pressure SMD varistor through-current capacity little; when circuit running into big electric current and passing through; it is susceptible to the deficiency of punch-through; a kind of super capacitance/voltage-resistor resistor is provided; there is super large capacitor and the quick dual-use function of voltage; it is mainly used in direct current ultralow pressure equipment and can effectively get rid of noise jamming, pre-antistatic, the normal work of protection load equipment.
For achieving the above object, present invention provide the technical scheme that a kind of super capacitance/voltage-resistor resistor, including shell, shell carries out the left electrode sealing fixing base and drawing through base jack by fluid sealant, right electrode, be coated and fixed varistor thin film chip in the enclosure, described varistor thin film chip is that internal layer scribbles silver electrode formation internal layer silver end face, outer layer scribbles silver electrode and forms the varistor thin film of outer layer silver end face, and insulating paper an equal amount of with varistor thin film is attached on outer layer silver end face tightly, the cylindrical tube being wound into, described left electrode, right electrode respectively with internal layer silver end face, outer layer silver end face tight contacts between, and respectively through left base jack and right base jack, draw outside base.
Taking the present invention of above-mentioned measure, main mounting bridge to be connected on direct current ultralow pressure device power supply (DPS) line both positive and negative polarity, wherein an electrode connects direct-flow positive pole, and another electrode connects negative pole, and element does not has polarity, and two electrodes arbitrarily connect regardless of both positive and negative polarity.When the DC voltage generation surge on power line, when circuit voltage flies up, the resistance value of super capacitance/voltage-resistor resistor can decline suddenly, and unnecessary voltage flows through negative pole by energy through varistor and releases away so that DC source keeps pressure constant state.When circuit voltage declines suddenly, the voltage of circuit, owing to self having bigger electric capacity, is supplemented by super capacitance/voltage-resistor resistor so that DC source keeps pressure constant state.When circuit has noise jamming and static interference, owing to the super capacitance/voltage-resistor resistor of bridge joint has bigger electric capacity, can effectively absorb clutter and electrostatic so that equipment DC source remains pressure constant state.
The invention have the advantages that
1. the present invention has super large capacitor and the quick dual-use function of voltage; through-current capacity is big; noise jamming and static interference can be effectively got rid of so that equipment DC source remains pressure constant state, thus effectively the normal of protection load equipment works in ultralow pressure DC equipment.
2. the present invention life-span is long, and product safety performance is high.
3. present configuration is simple, easy to process, and production efficiency is high, is suitable for mass industrialized production.
