Fixed inductors are essential components in many circuit designs involving power, signal, and data applications. The RCR664DNP-221K, a component of the RC line of fixed inductors from Panasonic, is a reliable and powerful inductor for a range of applications, and is manufactured with state-of-the-art technology to ensure excellent performance.

The RCR664DNP-221K is a non-shielded power inductor characterized by low resistance and high Q characteristics. It is a non-polarized type so it can easily be connected in either direction without a marked direction of polarity. Its high impedance-frequency characteristics are suitable for DC/DC converters and power supplies. The inductor offers an inductance of 2.2 uH with a DC resistance of 0.064 ohm at a rated current of 2.2 amps. It is capable of withstanding a large surge current of up to 265.0 amps, and its magnetic bias range of 1400mA to 1650mA is ideal for applications requiring high current rating.

The structure of the RCR664DNP-221K consists of two terminals and a bobbin case. The terminals are made of tin plated copper to provide easy electrical connectivity. The bobbin case is composed of a ceramic core and multi-layered, ceramic flux suppressers, in order to minimize flux leakage levels. The inductor is also encapsulated in a heat-resistant and flame-retardant resin for improve insulation layers and higher temperature stability.

The RCR664DNP-221K has a wide application field, including DC/DC converters, power supplies, adaptors, lighting circuits, and other various power applications. In terms of its working principle, as electric current flows through the inductor, it generates a magnetic field that creates a reverse voltage back to the inductor itself; this is called self-inductance. This self-induced voltage will oppose any change in current, thus enabling an inductor to limit or regulate the magnitude of a current change.

Additionally, the RCR664DNP-221K can be used in power filter applications, where different types of inductors are used together to reduce power noise. It can also be used in many inductor-capacitor filter circuits, which are used for noise suppression and frequency optimization. These circuits consist of parallel and/or series combinations of capacitors and inductors to reject and differentiate signals.

The RCR664DNP-221K is suitable for any application requiring reliable low DC resistance and high current capacity. With its impressive features and broad application field, the RCR664DNP-221K is an ideal inductor for application in any circuit design involving power, signal, and data applications.
