IWAS3222CZEB190JR1 概要
A wireless charging receiver coil is an inductive component used to capture energy transferred from a transmitting coil through electromagnetic induction. In the power path, the receiver coil converts magnetic flux into an electrical signal that is then rectified, filtered, and regulated by the receiving electronics. The coil therefore sits at the interface between the wireless power field and the device's power-management circuit.
The IWAS3222CZEB190JR1 combines 19.6 uH inductance with a 2.4 A current rating, making its electrical scale suitable for receiver-side power-transfer designs where the associated rectifier, capacitor, and regulator must be matched to the coil's inductance and resistance. The distributor listing also identifies a resistance value of 357 mOhm, while the manufacturer page identifies the product as a shielded wireless charging receiver coil.
Its specialized shield coating is intended to improve environmental protection and moisture resistance, particularly in humid operating environments. This makes the component relevant to portable electronics, wireless power accessories, and other systems requiring a robust receiver coil, although final suitability must be validated against the complete transmitter, receiver, thermal, mechanical, and electrical design.
The most important design consideration is system-level matching. The coil inductance, DC resistance, current capability, shield geometry, and operating temperature must be evaluated together with the transmitter characteristics and downstream regulator requirements. The manufacturer states that customers must validate that the product is suitable for a particular application because parameters and performance can vary by application and over time.
This page consolidates the verified distributor specifications, manufacturer environmental claims, source links, and application guidance for engineers evaluating IWAS3222CZEB190JR1. It also distinguishes verified data from information that is not present in the supplied sources, avoiding assumptions about package dimensions, exact pricing, or lifecycle status.

主な用途
IWAS3222CZEB190JR1 の用途: 6 件s: Wireless Charging Receiver Power Path, Portable Wireless Charging Accessories, Wireless Powering for Battery Devices, Wireless Powering in Humid Environments, High-Current Wireless Power Receiver Design, Consumer Wireless Charging Platform.
Wireless Charging Receiver Power Path
The IWAS3222CZEB190JR1 is intended for the receiver side of a wireless power-transfer system, where it captures magnetic energy from a transmitting coil and supplies the subsequent rectifier and regulator stage. Its 19.6 uH nominal inductance and distributor-reported 2.4 A rating provide the primary component parameters for initial system matching. The design must still verify coupling, resonant behavior, shield orientation, and downstream power-conversion requirements rather than treating the coil as a standalone power supply.
おすすめ
Portable Wireless Charging Accessories
The IWAS3222CZEB190JR1 can be evaluated for portable devices that receive power over an inductive wireless link, including accessories where cable-free convenience is important. Its specified operating range of -40 °C to +105 °C and moisture resistance up to 90% RH provide useful environmental context for enclosure and integration planning. The product must be validated in the final mechanical stack because foreign objects, alignment, body proximity, and enclosure materials can materially change coupling and heating.
おすすめ
Wireless Powering for Battery Devices
In a battery-powered product, the IWAS3222CZEB190JR1 serves as the inductive receiver element that transfers energy toward the battery-charging circuitry. The 19.6 uH inductance, 357 mOhm distributor-reported DC resistance, and 2.4 A current rating help define the initial electrical design envelope. Actual charging current and efficiency depend on transmitter power, alignment, rectifier loss, thermal conditions, and battery-charging limits, so the coil should not be treated as an independent current regulator.
おすすめ
Wireless Powering in Humid Environments
The IWAS3222CZEB190JR1's specialized shield coating is specifically described by Vishay as offering environmental protection and moisture resistance in high-humidity conditions up to 90% RH. This makes it a candidate for wireless charging assemblies used in humid or variable-environment equipment where the coil must remain mechanically and electrically stable. The claim should be incorporated into product validation alongside condensation, cleaning chemicals, sealing, corrosion, and the operating-temperature requirements of the complete transmitter-receiver system.
おすすめ
High-Current Wireless Power Receiver Design
The IWAS3222CZEB190JR1 is suitable for early evaluation in receiver architectures where the wireless power path may require a relatively high current capability. Its distributor-reported 2.4 A rating is an important starting constraint for inductor selection, copper-loss analysis, and thermal design. Designers should not equate the distributor rating directly with continuous delivered output current; the rectifier, PCB traces, thermal environment, transmitter power, and required efficiency determine the practical operating point.
おすすめ
Consumer Wireless Charging Platform
For a consumer wireless charging platform, the IWAS3222CZEB190JR1 can serve as a receiver coil candidate when the mechanical outline and electrical tuning match the selected transmitter. The part's one-coil, one-layer description, 19.6 uH nominal inductance, and shielded construction help define the baseline architecture. Product validation should include foreign-object detection, alignment tolerance, temperature rise, enclosure color and material, user exposure, and the required charging power across the usable placement area.

設計ノート
Do not select or replace the coil using nominal inductance alone. Confirm the mechanical outline, shield geometry, terminal arrangement, tuned frequency, DC resistance, current rating, and operating-temperature limits. A coil with the same 19.6 uH nominal value can behave differently when installed near metal, ferrite, a battery, an enclosure, or a foreign object, so system-level validation is mandatory.
Use the 2.4 A distributor-reported rating as a component-selection constraint, not as a guaranteed continuous output-current specification. The actual current is set by the transmitter, coupling, rectifier, regulator, and thermal design. Validate winding temperature, PCB copper loss, magnetic-field alignment, and startup behavior at the maximum intended charging power.
Place the receiver coil and its rectifier input stage according to the manufacturer's recommended topology, keeping high-current loop area small and routing sensitive feedback separately. Preserve the intended coil orientation and mechanical clearance because shield and neighboring conductors can alter coupling and resonant behavior. Confirm the final layout in the product enclosure rather than on an isolated bench setup.
Check coil temperature rise at the highest expected charging current and ambient temperature. The verified operating range reaches +105 °C, but that limit is not a thermal design target and does not describe acceptable internal temperature rise. Measure the assembled coil, rectifier, and regulator during worst-case loading, including repeated fast charging and nearby heat sources.
Wireless power performance is sensitive to alignment, foreign objects, conductive enclosures, ferrite placement, and shield interaction. Define test cases for nominal alignment, edge placement, object detection, temperature extremes, and high-humidity exposure. The stated 90% RH shield-coating capability does not validate the full charger unless the mechanical enclosure and electrical contacts are also qualified.
