Fixed inductors are small, passive electronic components composed of simple coils of wire. Fixed inductors are also sometimes known as chokes. These components can function as both inductors and transformers. They are used in a wide variety of applications, including power electronics, radio frequency (RF) circuits, and filters. The ER1641-272JP is a type of fixed inductor, and it has some unique features and specifications that make it suitable for certain applications.

The ER1641-272JP is an AEC-Q200 qualified, high-temperature coil form fixed inductor. It is designed to be used in automotive applications, because the high temperature tolerance ensures that it can withstand extended exposure to heat. The inductor features a ferrite dioxide core which is resistance to saturation. This increases stability, accuracy, and overall performance. It also helps reduce the loud buzzing noises often associated with inductors.

The ER1641-272JP is particularly suitable for use in high-temperature environments, such as those found in hybrid and electric vehicles. It can operate at temperatures up to -55°C to +155°C. The inductor is also resistant to moisture, dust, and other environmental elements. It features RoHS compliant lead-free termination, making it a safe choice for automotive and other applications.

In terms of electrical characteristics, the ER1641-272JP is a low-profile, shielded wire-wound inductor. It has an inductance value of 0.27mH and a DC resistance of 0.886 Ohm. The inductor can handle peak currents of up to 2.0 Amps. It is also rated for a high frequency of 9.7 kHz, meaning it can have a faster response time.

The ER1641-272JP also has a very low self-resonance frequency. This means that the inductor can maintain a consistent inductance even when exposed to rapidly changing current or voltage levels. This makes it suitable for use in high speed switching circuits. Additionally, this low-profile, shielded inductor has excellent noise suppression, making it ideal for applications where noise reduction is necessary.

To sum up, the ER1641-272JP is a high-temperature coil form fixed inductor that is well-suited for use in automotive applications. It is AEC-Q200 compliant and offers excellent electrical and environmental performance. It has a robust ferrite-dioxide core that makes it resistant to saturation, and its low self-resonance frequency provides consistent inductance values in high speed switching circuits. Additionally, its excellent noise suppression makes it a good choice for applications where noise reduction is important.
