Capacitors that rapidly store and release electric energy are key components in modern electronics and power systems. However, the most commonly used ones have low energy densities compared to other storage systems like batteries or fuel cells, which in turn cannot discharge and recharge rapidly without sustaining damage.

Solenoid and relay conjure visions of an ancient electromechanical world now replaced by all-electronic devices, smart motors, and more. That almost makes sense, as these two components in various forms have been with us for over 150 years. But don’t be fooled: Both are still indispensable devices … and remain viable choices for the conversion of electrical energy to mechanical motion (in the case of solenoids) or where a signal must control the on-off path of one or more other signals (in the case of relays).

The drive to use COTS (Commercial Off-The-Shelf) components in the space industry is growing since these parts allow to obtain higher performance at the system level, which is difficult to obtain using currently available space components. However, the use of COTS components has an inherent risk because of the lack of confidence in the traceability and the long-term performance of these parts as well as the new concerns affecting mostly this type of products (RoHS, counterfeit parts, long-term reliability, etc.).

The PolySwitch zeptoSMDC series provides overcurrent and overvoltage protection on the signal lines for both the lithium-ion battery pack ICs and fuel gauge. Resettable PPTCs do not require replacement after a fault event; they allow the circuit to return to the normal operating condition after the power has been removed and/or the overcurrent condition is eliminated.
