WTH0415T

Product Introduction

Sunlord WTH0415T is a wire-wound molded SMD power inductor from the WT series in Metric 0415. Its closed-magnetic-circuit construction keeps flux leakage and EMI low, while very low DC resistance and low AC loss (switching frequencies up to 5 MHz) give excellent saturation behaviour with no thermal aging and high reliability. Operating from -55~+155°C with inductance 0.33~1.0 μH — saturation current up to 13.0 and temperature-rise current up to 13.9 — it is built for the DC-DC power modules in smartphones, tablets, 5G modules, servers and base stations.

Core Advantages

• Wire Wound Molded: Sunlord WT-series molded construction — closed magnetic circuit for low flux leakage and EMI; stable at switching frequencies up to 5 MHz.
• Low DCR, high current: DCR from 4.8~12.5 mΩ; saturation current up to 13.0 — excellent saturation behaviour with no thermal aging.
• Full range: Metric 0415, inductance 0.33~1.0 μH, operating temperature -55~+155°C.
• Supply: YQM ELECTRONICS holds Sunlord stock with fast samples, datasheets and FAE support for volume programs.

Applications

FAQ

Q: Is the WTH0415T suitable for high-frequency DC-DC designs?

A: Yes — the molded construction keeps AC losses low and supports switching frequencies up to 5 MHz, ideal for compact high-frequency DC-DC converters.

Q: Does the closed magnetic circuit help with EMI?

A: Yes — the closed magnetic circuit greatly reduces flux leakage and EMI, which makes the WT series a good fit for densely packed boards.

Q: Are samples and datasheets available?

A: Yes — YQM ELECTRONICS stocks Sunlord WTH0415T with fast samples, datasheets and FAE support for volume programs.
