Film capacitors, also known as plastic film capacitors specially made using a plastic film as the dielectric, are used in many types of electronic circuits for blocking, coupling, bypassing, and filtering. The ECH-S1H474JZ is an especially popular axial-leaded, polymer-housed film capacitor from JinLong Electronics. It is designed specifically for bonding applications, offering a wide range of features that make it better than other capacitors in the same field.

Application Field

The ECH-S1H474JZ is used in many electronic circuits such as those dealing with amplifier peaking, filtering, bypassing, and blocking. It is useful for applications requiring an insulated construction, including medical equipment, automotive control systems, and power supplies. It is also well suited to noise suppression applications as it can be easily mounted into PCBs. For this reason, it is sometimes referred to as a “super capacitor”.

The ECH-S1H474JZ works best in capacitor-related applications that require high-frequency performance and small size. It is also designed to easily withstand voltage transients caused by lightning strike, and a host of other environmental stress factors. As a result, it is an ideal choice for installation in harsh environments that could be destructive to normal capacitors.

Working Principle

The ECH-S1H474JZ film capacitor is typically constructed using a metalized polyester film, a metallized polyethylene naphthalate film, a wound foil, a polypropylene electrolytic film, and metal electrodes. Each of these components play a role in the capacitor\'s particular characteristics, such as dielectric strength and temperature stability.

The metal electrodes create a barrier between the dielectric film and the metal electrodes, allowing for a charge to build up and discharge over time between them. This charge differential is what gives capacitors their characteristic property to reduce AC current. The ECH-S1H474JZ capacitor relies on the charge build up across the dielectric to produce a capacitance or voltage differential between the two metal electrodes.

The ECH-S1H474JZ capacitor is designed to never become overcharged, as a built-in resistor within the construction prevents it from doing so. The temperature stability of this device is also remarkable due to its patented design and the enclosure that helps to protect it from environmental influence. Its long-term stability ensures that it will still offer reliable performance for years on end, whatever the conditions.

Conclusion

The ECH-S1H474JZ film capacitor is designed to provide reliable performance in a wide variety of applications. Its construction ensures that it is ideal for use in high-frequency circuits, while the built-in resistor ensures that it cannot become overcharged. Its unique construction also provides excellent performance in temperature-dependent and hostile environment applications, making it an ideal choice for those more challenging applications.
