Feed-through capacitors are a type of device that is commonly used to ensure that electrical signals are safely conducted from a source to its destination or load. The SCI-9900-153 is a high-frequency feed-through capacitor designed to provide electromagnetic interference (EMI) shielding and signal integrity for frequencies from 10 kHz to 18 GHz. The device is composed of three components: a dielectric, a resistor and a capacitor. The dielectric is the insulation material that separates the conductors; the resistor is used for voltage regulation; and the capacitor is used to store energy.

SCI-9900-153 capacitors are designed with high-frequency performance, wide frequency range, low temperature coefficient, large capacitance, and high voltage operation. The capacitance can reach up to 1500 pF with an operating temperature range of -55°C to +125°C. This makes the SCI-9900-153 ideal for a variety of applications, including automotive electronics, telecommunications, medical equipment, avionics, computers, and more.

The SCI-9900-153 is an axial ceramic-encapsulated terminal capacitor, offering very high Q performance in a very small form factor. The device features a self-sealing feed-through capacitor, which is fastened securely to the PCB with an integrated flange and nut design. This feature allows the capacitor to be securely fastened to multiple PCBs, mounting holes, and other surfaces. The self-sealing design also prevents any water and moisture from leaking onto the board, protecting the chip from electrical failure.

The SCI-9900-153 feed-through capacitor also offers the advantage of high-level EMI shielding with low-level internal capacitance and resistance. This helps reduce the amount of both radiated and conducted EMI that can occur when transmitting signals. This in turn reduces the amount of noise that could interfere with the performance of the system by limiting the amount of unwanted high-frequency and transient signals that can occur.

The SCI-9900-153 operates on the principle of a tuned electrical circuit. A tuned circuit is a system that combines two or more elements in which the electrical response of the circuit is equal to the sum of the responses of the individual elements. This means that the SCI-9900-153 is capable of rejecting frequencies which are outside of the desired bandwidth. The amount of attenuation that the capacitor provides depends on the frequency, the size of the capacitor, and the number of capacitors used in the system.

In terms of its application field, the SCI-9900-153 feed-through capacitor offers an effective solution for a diverse range of high-frequency applications. The device is particularly well-suited for EMI shielding, power supply filtering, and RF signal conditioning as it offers several advantages such as high performance, low temperature coefficient, and low attenuation. The device is also suitable for applications such as medical instrumentation, military equipment, and commercial electronic equipment that require a high-frequency response and low power dissipation.

The SCI-9900-153 feed-through capacitor is a compact, robust, and reliable device. Its wide frequency range, low temperature coefficients, and high capacitance make it ideal for a variety of applications. With its integrated flange design, the capacitor is easy to install and is well-suited for situations that require high voltage operation and EMI shielding. As such, the SCI-9900-153 is a great choice for high-frequency applications.
