Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

Is BWCM0018101022NJL8 suitable for matching a 50 ohm RF line in a compact front-end or filter network?
BWCM0018101022NJL8 can be used in RF matching networks, but its 22 nH value, unshielded construction, and parasitic capacitance must be accounted for in the final impedance model. In a 50 ohm design, BWCM0018101022NJL8 is usually validated with S-parameter or bench tuning rather than selected by inductance alone, because layout and nearby conductors can shift the effective response.
Can BWCM0018101022NJL8 be used as a replacement for another 22 nH chip inductor from a different manufacturer?
BWCM0018101022NJL8 is not a drop-in replacement by inductance value alone. For replacement work, compare DCR, Q at the intended frequency, self-resonant frequency, package footprint, and current handling. BWCM0018101022NJL8 uses a nonstandard 1.80 mm x 1.00 mm body, so footprint compatibility and RF behavior both need verification before migration.
What layout precautions should I take when using BWCM0018101022NJL8 in a high-frequency RF design?
BWCM0018101022NJL8 is unshielded, so magnetic field coupling to adjacent traces, ground returns, and nearby inductors can affect performance. Keep the current loop small, place the part close to the network it serves, and avoid routing sensitive traces parallel to it. Ground structure and pad geometry can materially change the usable inductance at RF.
Is BWCM0018101022NJL8 appropriate for DC-DC converter output filtering or power path filtering?
BWCM0018101022NJL8 can work in some low-power filtering roles, but it is primarily an RF inductor, not a general power inductor. Its 1.3 A current rating and 86 mOhm max DCR may be acceptable for light filtering, but saturation behavior is not specified, so designs with large ripple current or fast transients need validation under worst-case load and temperature.
How does BWCM0018101022NJL8 behave at temperatures near the top of its rating range?
BWCM0018101022NJL8 is rated for -40°C to 125°C, which supports industrial environments, but higher temperature generally increases copper loss and can shift effective RF performance slightly through resistance change. For long-term use near the upper limit, verify dissipation, self-heating, and the surrounding board temperature profile rather than relying only on nominal room-temperature measurements.
Can BWCM0018101022NJL8 be used for impedance matching in antenna or transceiver circuits?
BWCM0018101022NJL8 is a plausible choice for small-signal RF matching, especially where 22 nH is close to the target value and the network is tuned in-circuit. Because it is unshielded and has a 3.45 GHz self-resonant frequency, the practical tuning range is bounded by the intended operating band and the parasitics of the PCB and adjacent components.
What should I check before substituting BWCM0018101022NJL8 into an existing PCB footprint?
For BWCM0018101022NJL8, confirm the land pattern matches the 1.80 mm x 1.00 mm package and that solder mask, pad length, and stencil volume are appropriate for this small nonstandard case. Even when the part physically fits, pad inductance and trace geometry can change RF response enough to require retuning.
Is BWCM0018101022NJL8 a good option when I need stable performance across production lots?
BWCM0018101022NJL8 has a ±5% inductance tolerance, which is reasonable for many RF applications, but production stability still depends on layout consistency, assembly quality, and measurement conditions. If the circuit is narrowband, confirm tuning margin across lot variation and at operating temperature, since the final response is often dominated by the complete network rather than the nominal part value.
How should I evaluate BWCM0018101022NJL8 if I am replacing a similar part from Coilcraft, Murata, or TDK?
BWCM0018101022NJL8 should be compared against the exact competitor part’s frequency curve, Q, DCR, SRF, and package geometry. Equivalent inductance does not guarantee equivalent RF loss or resonance behavior. For a replacement decision, measure insertion loss or matching performance in the actual circuit, because BWCM0018101022NJL8 may tune differently even when the nominal value matches.
Does BWCM0018101022NJL8 require any special handling or storage controls before assembly?
BWCM0018101022NJL8 is MSL 1 and RoHS3 compliant, so it does not impose special moisture-bake handling under normal conditions. Standard SMT storage and assembly controls are usually sufficient, but normal ESD and contamination controls still apply for RF assemblies where surface cleanliness affects repeatability.
When would BWCM0018101022NJL8 not be the right choice for a design?
BWCM0018101022NJL8 is a poor fit when the circuit needs magnetic shielding, high energy storage, or a clearly specified saturation current. It is also less attractive when the layout cannot tolerate RF coupling from an unshielded inductor or when the design needs a standard power-inductor footprint with more conservative power-handling data.
Can BWCM0018101022NJL8 be used in long-life industrial equipment with continuous operation?
BWCM0018101022NJL8 can be used in continuous-duty equipment if the applied current, ambient temperature, and board heat rise stay within limits. For long-life use, the main checks are thermal margin, solder joint reliability, vibration environment, and whether the RF performance remains acceptable as the surrounding assembly ages or is reworked.
