Tantalum wire is necessary in the production of both molded and coated chip capacitors because it acts as the lead wire from the anode to the lead frame. Cathode Application – Gas versus Dipping. A gas infusion process for the application of conductive polymers into the porous structure of tantalum anodes generates a higher margin than the alternative monomer

Lab Notes on Capacitors

Even short lengths of wire have considerable inductance, so mount the HF decoupling capacitors as close as possible to the IC, and ensure that leads consist of short, wide PC tracks. Ideally, HF decoupling capacitors should be surface-mount parts to eliminate lead inductance, but wire-ended capacitors are ok, providing the device leads are no

6 FAQs about [The role of the lead wires of the chip capacitor]

Why do capacitors have crimped leads?

This will isolate the capacitor from forces that it would otherwise experience during vibration, board flexing/bending, thermal expansion/contraction, etc. By providing the crimped leads at the factory, the board house does not require a machine to add those in-house.

What is a lead in a circuit?

The leads are often metal connections that run from the rest of the circuit to the materials that each component is made of. This design results in a very small capacitance between the ends of the leads where they connect to the device and very small inductances and resistances along each lead.

What is a 3 terminal chip-type capacitor?

Figure 5 shows the structural concept of a 3 terminal chip-type capacitor. A ground terminal is attached to each side of the chip, the dielectric is placed between the plates, and feed through electrodes and ground electrodes are alternately stacked up to create a feed through capacitor-like structure.

Why does a lead affect a radio frequency circuit?

Because the impedance of each component is a function of the frequency of the signals being passed through the device and the inductance and capacitance of the device, the leads can cause substantial variation in the properties of components in radio frequency circuits.

How do feedthrough capacitors work?

Feedthrough capacitors are used by making a mounting hole in the shielding case and soldering the ground electrode directly to the shielding case (plate). Since this type of capacitor has no residual inductance on the ground terminal side as well as on the signal terminal side, it can provide nearly ideal insertion loss characteristics.
