Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new Hi-Rel series of TANTAMOUNT? surface-mount solid tantalum molded chip capacitors for military and aerospace applications.
Available with high-reliability screening and surgeA transient variation in the current and/or potential at a point in the circuit. current testing options in accordance with MIL-PRF-55365, the Vishay Sprague T42 series combines a built-in fuse for fail-safe operation with high capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. and voltage ratings and low ESRLow Equivalent Series ResistanceLow Equivalent Series ResistanceLow Equivalent Series Resistance down to 80 milliohms at +25 degrees C and 100 kHz.
The capacitors released today are ideal for filtering, decouplingA decoupling capacitor is a capacitor used to decouple one part of an electrical network (circuit) from another. Noise caused by other circuit elements is shunted through the capacitor, reducing the effect they have on the rest of the circuit, and energy storage applications in weapons and radar systems, avionics, and space-based electronics. To protect against catastrophic failures in these safetyClass X capacitors are used in "across-the-line" applications where their failure would not lead to electric shock. Class X safety caps are used between the "live" wires carrying the incoming AC current. In this position, a capacitor failure should not cause any electrical shock hazards, rather, a capacitor failure "between-the-lines" would usually cause a fuse or circuit breaker to open.-critical applications, the devices' built-in fuse guarantees protection at 5 A for 10 ms and is optimized to ensure activation while avoiding false triggering. The T42 employs a multi-anodeAn electrodeA solid electric conductor through which an electric current enters or leaves in a medium through which current enters any nonmetallic conductor. "mirror" structure that reduces ESRLow Equivalent Series Resistance by at least 50 %. Each internal anodeAn electrodeA solid electric conductor through which an electric current enters or leaves in a medium through which current enters any nonmetallic conductor. within the device has a dedicated fuse, allowing unaffected anodes to maintain capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. in the unlikely event of a failure. Depending on the application, this fault-tolerant design allows for a degraded mode of operation rather than a complete loss of functionality.
Offered in the M2 case code, T42 series capacitors utilize Vishay's patented leadframeless multi-array packaging (MAP) technology for increased volumetric efficiency. Built on a glass-reinforced resin base, the device eliminates the problematic J-lead construction and associated current-loops, thereby reducing ESLLow equivalent series inductance. by two thirds that of traditional capacitors. The result is high capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. from 10 to 470 microfarads, with tolerances of 10 % and 20 %, and voltage ratings from 16 VDC to 75 VDC. With higher capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. than traditional devices, the capacitors reduce the overall component count and simplify designs.
The T42 series offers an operating temperature range of -55 degrees C to +85 degrees C, +125 degrees C with voltage derating, and maximum ripple currentThis applies to a DC application with a superimposed AC voltage. The ripple current rating is the maximum AC current the capacitor can handle. from 0.7 A to 1.8 A. RoHS-compliant, the devices are available with 100 % tin or tin/lead terminations.
