Tantalum chip caps with built-in fuse
4 June 2014
Passive Components
Vishay has introduced a new Hi-Rel series of TANTAMOUNT surface-mount solid tantalum moulded chip capacitors for military and aerospace applications. Available with high-reliability screening and surge 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 capacitance and voltage ratings, and low ESR down to 80 m at +25°C and 100 kHz.
The capacitors are ideal for filtering, decoupling and energy storage applications in weapons and radar systems, avionics and space-based electronics. To protect against catastrophic failures in these safety-critical applications, the devices’ built-in fuse guarantees protection at 5 A for 10 ms and is optimised to ensure activation while avoiding false triggering.
The T42 employs a multi-anode ‘mirror’ structure that reduces ESR by at least 50%. Each internal anode within the device has a dedicated fuse, allowing unaffected anodes to maintain capacitance 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 eliminate the problematic J-lead construction and associated current loops, thereby reducing ESL by two thirds that of traditional capacitors. The result is high capacitance from 10 μF to 470 μF, with tolerances of ±10% and ±20%, and voltage ratings from 16 V to 75 V d.c.
The T42 series offers an operating temperature range of -55°C to +85°C, +125°C with voltage derating, and maximum ripple current from 0,7 to 1,8 A. RoHS-compliant, the devices are available with 100% tin or tin/lead terminations.
