features and advantages ? connector and filter as all in one solution ? filtering for high frequencies up to 10ghz ? keying of the connector insures that the cables and the connector are mated correctly ? reverse polarity protection ? high currents up to 250a applications high frequency applications in an enclosure, where a connector and a filter is required. computer systems, 48vdc systems (widely used in telecom), 18v battery back-up power plants where power needs to be readily available, large enterprise servers migrating towards 48vdc. in all of these applications, on site installation is often a second thought and overlooked when budgeting for the total installed cost. the connector has been designed to reduce the total costs of ownership and maxi- mize the modularity of rack design or fast connectable applications. the acara connectors are manufactured to accommodate very high current connections up to 250a and for high frequency filtering up to 10ghz. the acara connector keeps inventory levels down and cuts cost. keying of the connector ensures that the cables and the connector are mated correctly. the capacitor has a very low internal series inductance. this provides a sup- pression performance over a much wider frequency rang than a conventional two-wire capacitor of equivalent value. concept due to the leads a normal capacitor has a self-inductance. these leads operate like small series inductances. figure 2. typical frequency response of a conventional 1f capacitor with 20mm leads compared to the ideal theoretical response. figure 1. typical frequency response of a 1f feedthrough capacitor compared to the ideal theoretical response. the acara connector has a current-carrying conductor passing through the center of the capacitor. this co-axial conductor is one terminal of the capacitor. the other terminal is the metal outer casing of the capacitor, which was specifically designe d for being attached to a grounded metal bulkhead. this design is common to all acara filters and ensures that any radio frequency currents carried on the central conductor are shunted to earth by the capacitor. because of the extremely low series inductance resulting from this type of construction, the self-resonant frequency of an acar a capacitor will be very high. a typical frequency response is shown in figure 1. as frequency increases, the impedance of the feedthrough capacitor decreases continuously to provide excellent performance to beyond 10ghz. some small resonances can be expected in the performance characteristics of acara capacitors as shown in figure 1. these are usually attributable to distributed inductance within the capacitor and can cause its high frequency response to vary slightly from the theoretical. with the acara filtered connectors you will have the best performance. high frequency (line) will be filtered to the ground. applications like computer systems will therefore be protected. the combination of connector and filter results in an effective solution to simplify the contacting concept.
connector afc100, 2 awg wire afc250, 2 awg wire the success of acara depends on a very low contact resistance, and this design provides a very high quality material and a clever metallization process so there is no risk of overheating effects. the hot-pluggable connector has a very low arcing between the male and female connector. acara is designed for 500 connect/disconnect cycles and 250 cycles under nominal load according ul1977 and en 60984 giving optimum performance and flexibility. servers, base stations, and telecom equip- ment can easily be connected and disconnected. the material used in the contact and the mechanical construction of acara are important to reach the service conditions of the customer application. the diagrams above show a typical temperature rise of a 100a and 250a connector. the contact resistance of the connector is most important. for example with 100a nominal load, the temperature rise of the contact is only approximately 17c. the patented acara connector family offers fast easy connecting and a long lifetime with hundreds of connect/disconnect cycles. to achieve this high conductivity copper is used which gives a low temperature rise. the copper material has good spring properties at contact interface and with good formability for crimping to finely stranded copper conductors. the spring system provides high mechanical shock/vibration stability with no contact bounce. typical insertion loss 100nf 220nf 470nf 600nf 1000nf 2100nf afc100, 2 awg wire afc250, 2 awg wire
