IWTX47R0EBEB240JR1 概述
A wireless charging transmitter coil is the resonant magnetic element on the primary (TX) side of an inductively-coupled power transfer link. The coil, together with a matching network capacitor, forms an LC tank that resonates at the Qi-specified 110-205 kHz band (low-power Qi) or at higher bands used by fast-charging proprietary protocols. The shield below the coil contains the magnetic flux and steers it toward the receiver coil while limiting stray field emissions. TX coils are larger and rated for higher current than RX coils because the transmitter actively drives the resonant current, while the receiver only captures it.
Key features of this part include the 24µH inductance at 200 kHz, 5% inductance tolerance for predictable resonant tuning, 20A current rating which keeps I²R losses under 1W at full drive, and 75mΩ maximum DCR which limits conduction loss and thermal rise. The integrated shielding reduces the bill of materials versus a separate ferrite sheet and improves coupling alignment tolerance with the receiver pad.
The IWTX47R0EBEB240JR1 is built on a single-layer double-sided PCB-style flat winding with an attached ferrite base. The flat, low-profile construction (~3.5 mm height typical) is optimized for placement under enclosures and integrates directly onto a transmitter PCB or a charging pad surface. Termination is by flying lead for soldering to the host PCB.
Typical applications include Qi-compliant wireless charging transmitters, charging pads for smartphones, smartwatches, and earbuds, industrial inductive power modules, medical device battery chargers, and automotive in-cabin charging cradles. The 24µH inductance makes it well-suited to low-power (5W) Qi BPP and mid-power (up to 15W) Qi EPP transmitter topologies paired with a half-bridge or full-bridge inverter.
When designing with this part, ensure the resonant capacitor is selected to place the LC tank at the protocol target frequency and that thermal management accounts for sustained 20A drive current in enclosed housings. Always validate coupling coefficient with the chosen receiver coil over the full range of device placement positions.

典型应用
IWTX47R0EBEB240JR1 适用于 6 应用s: Qi BPP 5W Wireless Charging Pad, Qi EPP 15W Fast Wireless Charger, Smartwatch and Wearable Charging Cradle, Medical Device Battery Charger, Automotive In-Cabin Phone Charging Tray, Industrial Inductive Power Module.
Qi BPP 5W Wireless Charging Pad
The IWTX47R0EBEB240JR1's 24 µH nominal inductance and 20 A current rating make it well-suited for Qi Baseline Power Profile (BPP) 5W single-coil transmitter designs operating in the 110-205 kHz Qi band. The integrated ferrite shield contains stray magnetic field on the underside of the pad, allowing the TX module to be placed directly on a desktop or nightstand without additional EMI shielding. The 75 mΩ maximum DCR keeps I²R conduction loss under 1 W at the typical 8 A RMS BPP drive current, so the pad surface stays within touch-safe temperatures during continuous overnight charging of smartphones and earbuds. Used together with a half-bridge inverter IC such as the BQ50002A or a discrete GaN driver, this coil forms the resonant tank whose Q-factor dominates overall system efficiency (typically 70-80% for BPP).
推荐
Qi EPP 15W Fast Wireless Charger
In Qi Extended Power Profile (EPP) 15W transmitters the IWTX47R0EBEB240JR1 supplies the resonant inductance for a full-bridge inverter that delivers up to 15W to EPP-certified receivers such as recent smartphones. The 20A continuous current rating provides comfortable headroom above the ~10 A RMS drive level required at EPP power levels, while the 75 mΩ DCR limits copper losses to roughly 0.75 W per phase. The integrated ferrite shield is essential in EPP designs because higher operating flux density produces stronger stray fields; without proper shielding the pad can interfere with nearby electronics and fail Qi magnetic-field emission limits. Pair this coil with an EPP controller such as the BQ500215 and adjust the resonant capacitor to place the LC tank at the Qi center frequency.
推荐
Smartwatch and Wearable Charging Cradle
Compact wearable chargers benefit from the IWTX47R0EBEB240JR1's flat 2-layer winding and integrated ferrite shield, which together keep the TX module height under 4 mm while still delivering up to 5W through a small receiver coil in the watch body. The 24 µH inductance is well-matched to low-power Qi topologies targeting smartwatch-class receivers (typically 2.5W-5W), and the 75 mΩ DCR ensures the cradle does not overheat in enclosed nightstand environments. The flying-lead termination simplifies routing to a small PCB tucked into the cradle base, and the integrated shield eliminates a separate ferrite sheet — important for very compact wearable designs.
推荐
Medical Device Battery Charger
For inductive charging cradles used with medical devices such as hearing aids, sleep apnea masks, or handheld diagnostic tools, the IWTX47R0EBEB240JR1 provides the TX-side inductance with the predictable ±5% tolerance needed for FDA-traceable design verification. The 24 µH value supports low-power Qi-compatible receivers in the 1W-5W range typical of medical-grade inductive charging, while the integrated ferrite shield limits stray magnetic field to within IEC 60601-1 EMI margins. The 20A current rating gives substantial derating margin for medical-grade designs that often require 50% or more current derating over industrial designs.
推荐
Automotive In-Cabin Phone Charging Tray
The IWTX47R0EBEB240JR1 can serve as the transmitter coil inside an automotive center-console phone-charging tray, delivering 5W-15W to Qi-compliant phones. The integrated ferrite shield confines the magnetic field within the tray volume so it does not interfere with the infotainment bus, CAN, or sensitive analog sensors, and the 75 mΩ DCR keeps the TX pad temperature within the touch-safe limits required for cabin-mounted surfaces (typically < 55 °C). For full automotive-grade compliance, the design should be qualified to AEC-Q100/-Q200 depending on the inverter topology — the coil itself is a passive element and does not require a per-component automotive qualification letter.
推荐
Industrial Inductive Power Module
In industrial environments where connectors are unreliable due to dust, vibration, or wash-down conditions, the IWTX47R0EBEB240JR1 enables contactless power delivery to sensors, HMIs, and small actuators. The 20A continuous current rating and 24 µH inductance pair with a half-bridge inverter to deliver 5W-15W across a 5-10 mm air gap, while the integrated ferrite shield maintains coupling efficiency even when the receiver is mounted on a non-metallic or lightly-metallic surface. Industrial applications often use a custom resonant frequency rather than Qi; the 24 µH value is a flexible starting point for designing around 100-300 kHz proprietary inductive links.

关键差异点
- Integrated ferrite shield eliminates separate ferrite sheet BOM （对比 Generic TX coil without integrated shield)
- 20A current rating supports EPP 15W Qi fast charging （对比 Lower-current 5-10A TX coils)
- Low 75 mΩ DCR minimizes conduction loss at Qi frequency （对比 Generic 100-150 mΩ TX coils)
设计说明
Place the IWTX47R0EBEB240JR1 flat on the TX PCB with the integrated ferrite shield facing down toward the receiver pad. Maintain at least 3 mm clearance from any ferromagnetic components or chassis metal to prevent flux leakage and eddy-current heating. The two flying leads should be routed symmetrically to the resonant capacitor and inverter switching node to minimize parasitic loop inductance, which can detune the resonant tank and reduce efficiency by 5-10%.
Estimated: at the rated 20 A continuous current with 75 mΩ DCR, copper conduction loss is approximately 30 W (P = I² × R = 400 × 0.075). Sustained operation requires active cooling or pulsed drive with adequate off-time. Mount the coil on a thermally conductive PCB pad (≥ 4 oz copper) and ensure the housing provides natural-convection airflow around the coil. For continuous BPP 5W drive at typical 6 A, losses are around 2.7 W — manageable without active cooling.
Do not assume the 24 µH inductance is flat across frequency — actual inductance rolls off above the self-resonant frequency (SRF) and shifts with DC bias current. Always tune the resonant capacitor using an LCR meter at the actual operating drive level. Additionally, never block the ferrite shield with metallic tape or labels — even a thin foil layer can dramatically reduce coupling and trigger Qi foreign-object detection (FOD) shutdown.
合规信息
RoHS and REACH compliance per Vishay product documentation 34600. Coil is a passive inductive component — AEC-Q100/-Q200 qualification is not directly applicable at the component level; system-level automotive qualification is governed by the inverter IC and PCB design.
