Tantalum capacitors are a type of capacitor that utilizes tantalum, a metallic element, as the primary component of its construction. They are notable for their high capacitance and low ESR (equivalent series resistance). The M39003/01-8277H are a series of surface mount tantalum capacitors that are designed to meet the stringent environmental standards required for military and aerospace applications. The M39003/01-8277H is a high-reliability, high-temperature capacitor that is designed for use in high temperature, high humidity, and high shock/vibration applications.

The M39003/01-8277H is constructed of immobilized, non-conductive resin with a special hard plastic coating that is highly resistant to humidity, temperature extremes, and vibration. The dielectric layer is then encased in a hermetic seal that is resistant to temperature, vibration, and moisture. This makes the M39003/01-8277H able to withstand temperature cycling in excess of 200°C, vibration up to 20g\'s, and shock up to 600g\'s.

The M39003/01-8277H is also rated for a voltage of up to 100 volts, a capacitance of up to 1000 uf with a maximum capacitance tolerance of 20%. They are also rated for a service temperature range of -55°C to +105°C. Additionally, they come in a variety of sizes for both through-hole and surface mount applications ranging from 3mm x 4.3mm to 5.8mm x 10.9mm.

The M39003/01-8277H uses a "sponge" capacitance element that is constructed of spirolink piezoelectric material with a polymeric binder that is immobilized in the non-conductive epoxy resin with a hard plastic coating. The spirolink element is constructed of sheets of piezoelectric material that are stacked and interlocked together to form a solid mass. The metal layers are formed as the spirolink material is inserted into the epoxy resin and then the spirolink material is plated with an electro-conductive metal. This increases the surface area for more efficient charge and discharge of electricity.

The base layers of the M39003/01-8277H are formed with aluminum and a ferroelectric ceramic material. The aluminum is plated with an insulating layer of RTV silicone and then the ferroelectric ceramic material is added. The ceramic material is used to reduce the self-induced noise generated by the capacitor. The cores are then attached to the substrate using surface mount technology.

The M39003/01-8277H utilizes a unique electro-conductive epoxy attachment technology to ensure that the capacitor has a stable and reliable electrical connection to the circuit board. This attachment technology also isolates the elective circuits from any moisture or chemicals that may be present in the environment. The M39003/01-8277H can withstand humidity levels of up to 100%, as well as temperatures up to 105°C.

The M39003/01-8277H is a high-reliability, high-temperature surface mount tantalum capacitor that is designed for use in severe environmental conditions. It utilizes an immobilized, non-conductive construction and a hermetic seal for a robust design that can withstand extreme conditions. It also utilizes a unique electro-conductive epoxy attachment technology that ensures a reliable electrical connection between the capacitor and the circuit board. With its high capacitance, low ESR, and wide temperature and humidity range, the M39003/01-8277H is an ideal choice for military and aerospace applications.
