Q1: What are the key features of the SRP5015TA‑4R7M?
The SRP5015TA‑4R7M is a shielded, wire‑wound power inductor with a carbonyl powder core, rated for 4.7 µH inductance. It can handle an RMS current of 2.7 A and has a saturation current of up to 4 A. Its DC resistance is low—118 mΩ typical—which helps minimize power loss, and it is built to automotive-grade standards (AEC-Q200), making it very robust under harsh conditions. It supports a wide operating temperature range (−40 °C to +150 °C) and its shielded construction helps reduce electromagnetic interference.
Q2: What is the SRP5015TA‑4R7M commonly used for?
This inductor is especially useful in power supply circuits, such as DC‑DC converters and regulators, where stable inductance and high current capacity are essential. Thanks to its high saturation current and strong thermal performance, it’s also well-suited for automotive systems (e.g., driver-assistance electronics), telecommunications, and other power‑management applications.
Q3: Are there alternative parts to the SRP5015TA‑4R7M?
Yes, there are several other options to consider depending on your design requirements:
1.Other inductors in the same SRP5015TA series, like the SRP5015TA-5R6M (5.6 µH) or SRP5015TA-3R3M (3.3 µH), provide similar performance but scaled inductance and current ratings.
2.If you need a non-shielded inductor or different core material, power inductors from other Bourns families (or from other manufacturers like TDK or Murata) might also work—but you’ll need to check that their current rating, saturation, and size match your application.
